+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.
+ *
+ * `ngApp` is the easiest, and most common way to bootstrap an application.
+ *
+
+
+
+ I can add: {{a}} + {{b}} = {{ a+b }}

+ * Using `ngStrictDi`, you would see something like this:
+ *
+
+
+
+
+ I can add: {{a}} + {{b}} = {{ a+b }}
+
+
This renders because the controller does not fail to

+/**
+ * @ngdoc function
+ * @name angular.element
+ * @module ng
+ * @kind function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ *
+ * If jQuery is available, `angular.element` is an alias for the
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
+ *
+ * jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most
+ * commonly needed functionality with the goal of having a very small footprint.
+ *
+ * To use `jQuery`, simply ensure it is loaded before the `angular.js` file.
+ *
+ * **Note:** all element references in Angular are always wrapped with jQuery or
+ * jqLite; they are never raw DOM references.
+ *
+ * ## Angular's jqLite
+ * jqLite provides only the following jQuery methods:
+ *
+ * - [`addClass()`](http://api.jquery.com/addClass/)
+ * - [`after()`](http://api.jquery.com/after/)
+ * - [`append()`](http://api.jquery.com/append/)
+ * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
+ * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+ * - [`clone()`](http://api.jquery.com/clone/)
+ * - [`contents()`](http://api.jquery.com/contents/)
+ * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`. As a setter, does not convert numbers to strings or append 'px'.
+ * - [`data()`](http://api.jquery.com/data/)
+ * - [`detach()`](http://api.jquery.com/detach/)
+ * - [`empty()`](http://api.jquery.com/empty/)
+ * - [`eq()`](http://api.jquery.com/eq/)
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
+ * - [`html()`](http://api.jquery.com/html/)
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+ * - [`prepend()`](http://api.jquery.com/prepend/)
+ * - [`prop()`](http://api.jquery.com/prop/)
+ * - [`ready()`](http://api.jquery.com/ready/)
+ * - [`remove()`](http://api.jquery.com/remove/)
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
+ * - [`removeClass()`](http://api.jquery.com/removeClass/)
+ * - [`removeData()`](http://api.jquery.com/removeData/)
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+ * - [`text()`](http://api.jquery.com/text/)
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/)
+ * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
+ * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces
+ * - [`val()`](http://api.jquery.com/val/)
+ * - [`wrap()`](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
+ * element before it is removed.
+ *
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ * retrieves controller associated with the `ngController` directive. If `name` is provided as
+ * camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ * `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
+ * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
+ * be enabled.
+ * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
+ * current element. This getter should be used only on elements that contain a directive which starts a new isolate
+ * scope. Calling `scope()` on this element always returns the original non-isolate scope.
+ * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ * parent element is reached.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

+ *
+ * // use the injector to kick off your application

+ *
+ * In the following example a new block of HTML containing a `ng-controller`

+ * ```js
+ * // inferred (only works if code not minified/obfuscated)

+ *
+ * If a function has an `$inject` property and its value is an array of strings, then the strings
+ * represent names of services to be injected into the function.
+ * ```js
+ * // Given
+ * var MyController = function(obfuscatedScope, obfuscatedRoute) {
+ * // ...
+ * }
+ * // Define function dependencies
+ * MyController['$inject'] = ['$scope', '$route'];
+ *
+ * // Then
+ * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * ```
+ *
+ * # The array notation
+ *
+ * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+ * is very inconvenient. In these situations using the array notation to specify the dependencies in
+ * a way that survives minification is a better choice:
+ *
+ * ```js
+ * // We wish to write this (not minification / obfuscation safe)
+ * injector.invoke(function($compile, $rootScope) {
+ * // ...
+ * });
+ *
+ * // We are forced to write break inlining
+ * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+ * // ...
+ * };
+ * tmpFn.$inject = ['$compile', '$rootScope'];
+ * injector.invoke(tmpFn);
+ *
+ * // To better support inline function the inline annotation is supported
+ * injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+ * // ...
+ * }]);
+ *
+ * // Therefore
+ * expect(injector.annotate(
+ * ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
+ * ).toEqual(['$compile', '$rootScope']);
+ * ```
+ *
+ * @param {Function|Array.} fn Function for which dependent service names need to
+ * be retrieved as described above.
+ *
+ * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
+ *
+ * @returns {Array.} The names of the services which the function requires.

+ *
+ * @description
+ *
+ * The {@link auto.$provide $provide} service has a number of methods for registering components
+ * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
+ * {@link angular.Module}.
+ *
+ * An Angular **service** is a singleton object created by a **service factory**. These **service
+ * factories** are functions which, in turn, are created by a **service provider**.
+ * The **service providers** are constructor functions. When instantiated they must contain a
+ * property called `$get`, which holds the **service factory** function.
+ *
+ * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
+ * correct **service provider**, instantiating it and then calling its `$get` **service factory**
+ * function to get the instance of the **service**.
+ *
+ * Often services have no configuration options and there is no need to add methods to the service
+ * provider. The provider will be no more than a constructor function with a `$get` property. For
+ * these cases the {@link auto.$provide $provide} service has additional helper methods to register
+ * services without specifying a provider.
+ *
+ * * {@link auto.$provide#provider provider(provider)} - registers a **service provider** with the
+ * {@link auto.$injector $injector}
+ * * {@link auto.$provide#constant constant(obj)} - registers a value/object that can be accessed by
+ * providers and services.
+ * * {@link auto.$provide#value value(obj)} - registers a value/object that can only be accessed by
+ * services, not providers.
+ * * {@link auto.$provide#factory factory(fn)} - registers a service **factory function**, `fn`,
+ * that will be wrapped in a **service provider** object, whose `$get` property will contain the
+ * given factory function.
+ * * {@link auto.$provide#service service(class)} - registers a **constructor function**, `class`
+ * that will be wrapped in a **service provider** object, whose `$get` property will instantiate
+ * a new object using the given constructor function.
+ *
+ * See the individual methods for more information and examples.

+/**
+ * @ngdoc method
+ * @name $provide#provider
+ * @description
+ *
+ * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
+ * are constructor functions, whose instances are responsible for "providing" a factory for a
+ * service.
+ *
+ * Service provider names start with the name of the service they provide followed by `Provider`.
+ * For example, the {@link ng.$log $log} service has a provider called
+ * {@link ng.$logProvider $logProvider}.
+ *
+ * Service provider objects can have additional methods which allow configuration of the provider
+ * and its service. Importantly, you can configure what kind of service is created by the `$get`
+ * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+ * method {@link ng.$logProvider#debugEnabled debugEnabled}
+ * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+ * console or not.
+ *
+ * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+ 'Provider'` key.
+ * @param {(Object|function())} provider If the provider is:
+ *
+ * - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+ * {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
+ * - `Constructor`: a new instance of the provider will be created using
+ * {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
+ *
+ * @returns {Object} registered provider instance
+
+ * @example
+ *
+ * The following example shows how to create a simple event tracking service and register it using
+ * {@link auto.$provide#provider $provide.provider()}.
+ *
+ * ```js
+ * // Define the eventTracker provider
+ * function EventTrackerProvider() {
+ * var trackingUrl = '/track';
+ *
+ * // A provider method for configuring where the tracked events should been saved
+ * this.setTrackingUrl = function(url) {

+ * // The service factory function
+ * this.$get = ['$http', function($http) {

+ * // Call this to save the tracked events to the trackingUrl
+ * save: function() {

+ * Compiles an HTML string or DOM into a template and produces a template function, which
+ * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
+ *
+ * The compilation is a process of walking the DOM tree and matching DOM elements to
+ * {@link ng.$compileProvider#directive directives}.
+ *
+ *
+ * **Note:** This document is an in-depth reference of all directive options.
+ * For a gentle introduction to directives with examples of common use cases,
+ * see the {@link guide/directive directive guide}.
+ *
+ *
+ * ## Comprehensive Directive API
+ *
+ * There are many different options for a directive.
+ *
+ * The difference resides in the return value of the factory function.
+ * You can either return a "Directive Definition Object" (see below) that defines the directive properties,
+ * or just the `postLink` function (all other properties will have the default values).
+ *
+ *
+ * **Best Practice:** It's recommended to use the "directive definition object" form.
+ *
+ *
+ * Here's an example directive declared with a Directive Definition Object:
+ *
+ * ```js
+ * var myModule = angular.module(...);
+ *
+ * myModule.directive('directiveName', function factory(injectables) {
+ * var directiveDefinitionObject = {
+ * priority: 0,
+ * template: '
', // or // function(tElement, tAttrs) { ... },
+ * // or
+ * // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
+ * transclude: false,
+ * restrict: 'A',
+ * templateNamespace: 'html',
+ * scope: false,
+ * controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
+ * controllerAs: 'stringIdentifier',
+ * bindToController: false,
+ * require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
+ * compile: function compile(tElement, tAttrs, transclude) {
+ * return {
+ * pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ * post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ * }
+ * // or
+ * // return function postLink( ... ) { ... }
+ * },
+ * // or
+ * // link: {
+ * // pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ * // post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ * // }
+ * // or
+ * // link: function postLink( ... ) { ... }
+ * };
+ * return directiveDefinitionObject;
+ * });
+ * ```
+ *
+ *
+ * **Note:** Any unspecified options will use the default value. You can see the default values below.
+ *
+ *
+ * Therefore the above can be simplified as:
+ *
+ * ```js
+ * var myModule = angular.module(...);
+ *
+ * myModule.directive('directiveName', function factory(injectables) {
+ * var directiveDefinitionObject = {
+ * link: function postLink(scope, iElement, iAttrs) { ... }
+ * };
+ * return directiveDefinitionObject;
+ * // or
+ * // return function postLink(scope, iElement, iAttrs) { ... }
+ * });
+ * ```
+ *
+ *
+ *
+ * ### Directive Definition Object
+ *
+ * The directive definition object provides instructions to the {@link ng.$compile
+ * compiler}. The attributes are:
+ *
+ * #### `multiElement`
+ * When this property is set to true, the HTML compiler will collect DOM nodes between
+ * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
+ * together as the directive elements. It is recommended that this feature be used on directives
+ * which are not strictly behavioural (such as {@link ngClick}), and which
+ * do not manipulate or replace child nodes (such as {@link ngInclude}).
+ *
+ * #### `priority`
+ * When there are multiple directives defined on a single DOM element, sometimes it
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+ * are also run in priority order, but post-link functions are run in reverse order. The order
+ * of directives with the same priority is undefined. The default priority is `0`.
+ *
+ * #### `terminal`
+ * If set to true then the current `priority` will be the last set of directives
+ * which will execute (any directives at the current priority will still execute
+ * as the order of execution on same `priority` is undefined). Note that expressions
+ * and other directives used in the directive's template will also be excluded from execution.
+ *
+ * #### `scope`
+ * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the
+ * same element request a new scope, only one new scope is created. The new scope rule does not
+ * apply for the root of the template since the root of the template always gets a new scope.
+ *
+ * **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from
+ * normal scope in that it does not prototypically inherit from the parent scope. This is useful
+ * when creating reusable components, which should not accidentally read or modify data in the
+ * parent scope.
+ *
+ * The 'isolate' scope takes an object hash which defines a set of local scope properties
+ * derived from the parent scope. These local properties are useful for aliasing values for
+ * templates. Locals definition is a hash of local scope property to its source:
+ *
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+ * always a string since DOM attributes are strings. If no `attr` name is specified then the
+ * attribute name is assumed to be the same as the local name.
+ * Given `` and widget definition
+ * of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
+ * the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
+ * `localName` property on the widget scope. The `name` is read from the parent scope (not
+ * component scope).
+ *
+ * * `=` or `=attr` - set up bi-directional binding between a local scope property and the
+ * parent scope property of name defined via the value of the `attr` attribute. If no `attr`
+ * name is specified then the attribute name is assumed to be the same as the local name.
+ * Given `` and widget definition of
+ * `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the
+ * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
+ * in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent
+ * scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
+ * can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If
+ * you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use
+ * `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional).
+ *
+ * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
+ * If no `attr` name is specified then the attribute name is assumed to be the same as the
+ * local name. Given `` and widget definition of
+ * `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to
+ * a function wrapper for the `count = count + value` expression. Often it's desirable to
+ * pass data from the isolated scope via an expression to the parent scope, this can be
+ * done by passing a map of local variable names and values into the expression wrapper fn.
+ * For example, if the expression is `increment(amount)` then we can specify the amount value
+ * by calling the `localFn` as `localFn({amount: 22})`.
+ *
+ *
+ * #### `bindToController`
+ * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController: true` will
+ * allow a component to have its properties bound to the controller, rather than to scope. When the controller
+ * is instantiated, the initial values of the isolate scope bindings are already available.
+ *
+ * #### `controller`
+ * Controller constructor function. The controller is instantiated before the
+ * pre-linking phase and it is shared with other directives (see
+ * `require` attribute). This allows the directives to communicate with each other and augment
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+ *
+ * * `$scope` - Current scope associated with the element
+ * * `$element` - Current element
+ * * `$attrs` - Current attributes object for the element
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
+ * `function([scope], cloneLinkingFn, futureParentElement)`.
+ * * `scope`: optional argument to override the scope.
+ * * `cloneLinkingFn`: optional argument to create clones of the original transcluded content.
+ * * `futureParentElement`:
+ * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
+ * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
+ * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
+ * and when the `cloneLinkinFn` is passed,
+ * as those elements need to created and cloned in a special way when they are defined outside their
+ * usual containers (e.g. like ``).
+ * * See also the `directive.templateNamespace` property.
+ *
+ *
+ * #### `require`
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
+ * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the
+ * injected argument will be an array in corresponding order. If no such directive can be
+ * found, or if the directive does not have a controller, then an error is raised (unless no link function
+ * is specified, in which case error checking is skipped). The name can be prefixed with:
+ *
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+ * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
+ * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+ * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
+ * `null` to the `link` fn if not found.
+ * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
+ * `null` to the `link` fn if not found.
+ *
+ *
+ * #### `controllerAs`
+ * Identifier name for a reference to the controller in the directive's scope.
+ * This allows the controller to be referenced from the directive template. The directive
+ * needs to define a scope for this configuration to be used. Useful in the case when
+ * directive is used as component.
+ *
+ *
+ * #### `restrict`
+ * String of subset of `EACM` which restricts the directive to a specific directive
+ * declaration style. If omitted, the defaults (elements and attributes) are used.
+ *
+ * * `E` - Element name (default): `
`
+ * * `C` - Class: `
`
+ * * `M` - Comment: ``
+ *
+ *
+ * #### `templateNamespace`
+ * String representing the document type used by the markup in the template.
+ * AngularJS needs this information as those elements need to be created and cloned
+ * in a special way when they are defined outside their usual containers like `` and ``.
+ *
+ * * `html` - All root nodes in the template are HTML. Root nodes may also be
+ * top-level elements such as `` or ``.
+ * * `svg` - The root nodes in the template are SVG elements (excluding ``).
+ * * `math` - The root nodes in the template are MathML elements (excluding ``).
+ *
+ * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
+ *
+ * #### `template`
+ * HTML markup that may:
+ * * Replace the contents of the directive's element (default).
+ * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
+ * * Wrap the contents of the directive's element (if `transclude` is true).
+ *
+ * Value may be:
+ *
+ * * A string. For example `{{delete_str}}
`.
+ * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
+ * function api below) and returns a string value.
+ *
+ *
+ * #### `templateUrl`
+ * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
+ *
+ * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
+ * for later when the template has been resolved. In the meantime it will continue to compile and link
+ * sibling and parent elements as though this element had not contained any directives.
+ *
+ * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
+ * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
+ * case when only one deeply nested directive has `templateUrl`.
+ *
+ * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
+ *
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+ * a string value representing the url. In either case, the template URL is passed through {@link
+ * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+ *
+ *
+ * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
+ * specify what the template should replace. Defaults to `false`.
+ *
+ * * `true` - the template will replace the directive's element.
+ * * `false` - the template will replace the contents of the directive's element.
+ *
+ * The replacement process migrates all of the attributes / classes from the old element to the new
+ * one. See the {@link guide/directive#template-expanding-directive
+ * Directives Guide} for an example.
+ *
+ * There are very few scenarios where element replacement is required for the application function,
+ * the main one being reusable custom components that are used within SVG contexts
+ * (because SVG doesn't work with custom elements in the DOM tree).
+ *
+ * #### `transclude`
+ * Extract the contents of the element where the directive appears and make it available to the directive.
+ * The contents are compiled and provided to the directive as a **transclusion function**. See the
+ * {@link $compile#transclusion Transclusion} section below.
+ *
+ * There are two kinds of transclusion depending upon whether you want to transclude just the contents of the
+ * directive's element or the entire element:
+ *
+ * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
+ * * `'element'` - transclude the whole of the directive's element including any directives on this
+ * element that defined at a lower priority than this directive. When used, the `template`
+ * property is ignored.
+ *
+ *
+ * #### `compile`
+ *
+ * ```js
+ * function compile(tElement, tAttrs, transclude) { ... }
+ * ```
+ *
+ * The compile function deals with transforming the template DOM. Since most directives do not do
+ * template transformation, it is not used often. The compile function takes the following arguments:
+ *
+ * * `tElement` - template element - The element where the directive has been declared. It is
+ * safe to do template transformation on the element and child elements only.
+ *
+ * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+ * between all directive compile functions.
+ *
+ * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+ *
+ *
+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ *
+
+ *
+ * **Note:** The compile function cannot handle directives that recursively use themselves in their
+ * own templates or compile functions. Compiling these directives results in an infinite loop and a
+ * stack overflow errors.
+ *
+ * This can be avoided by manually using $compile in the postLink function to imperatively compile
+ * a directive's template instead of relying on automatic template compilation via `template` or
+ * `templateUrl` declaration or manual compilation inside the compile function.
+ *
+ *
+ *
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ * e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ * to the link function instead.
+ *
+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ * `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ * control when a linking function should be called during the linking phase. See info about
+ * pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * ```js
+ * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * ```
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+ * directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+ *
+ * * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ * manipulate the children of the element only in `postLink` function since the children have
+ * already been linked.
+ *
+ * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ * between all directive linking functions.
+ *
+ * * `controller` - the directive's required controller instance(s) - Instances are shared
+ * among all directives, which allows the directives to use the controllers as a communication
+ * channel. The exact value depends on the directive's `require` property:
+ * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+ * * `string`: the controller instance
+ * * `array`: array of controller instances
+ *
+ * If a required controller cannot be found, and it is optional, the instance is `null`,
+ * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+ *
+ * Note that you can also require the directive's own controller - it will be made available like
+ * any other controller.
+ *
+ * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ * This is the same as the `$transclude`
+ * parameter of directive controllers, see there for details.
+ * `function([scope], cloneLinkingFn, futureParentElement)`.
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked.
+ *
+ * Note that child elements that contain `templateUrl` directives will not have been compiled
+ * and linked since they are waiting for their template to load asynchronously and their own
+ * compilation and linking has been suspended until that occurs.
+ *
+ * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+ * for their async templates to be resolved.
+ *
+ *
+ * ### Transclusion
+ *
+ * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
+ * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+ * scope from where they were taken.
+ *
+ * Transclusion is used (often with {@link ngTransclude}) to insert the
+ * original contents of a directive's element into a specified place in the template of the directive.
+ * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+ * content has access to the properties on the scope from which it was taken, even if the directive
+ * has isolated scope.
+ * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+ *
+ * This makes it possible for the widget to have private state for its template, while the transcluded
+ * content has access to its originating scope.
+ *
+ *
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+ * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+ * Testing Transclusion Directives}.
+ *
+ *
+ * #### Transclusion Functions
+ *
+ * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+ * function** to the directive's `link` function and `controller`. This transclusion function is a special
+ * **linking function** that will return the compiled contents linked to a new transclusion scope.
+ *
+ *
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+ * ngTransclude will deal with it for us.
+ *
+ *
+ * If you want to manually control the insertion and removal of the transcluded content in your directive
+ * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+ * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+ *
+ * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+ * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+ * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
+ *
+ *
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function
+ * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+ *
+ *
+ * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+ * attach function**:
+ *
+ * ```js
+ * var transcludedContent, transclusionScope;
+ *
+ * $transclude(function(clone, scope) {
+ * element.append(clone);
+ * transcludedContent = clone;
+ * transclusionScope = scope;
+ * });
+ * ```
+ *
+ * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+ * associated transclusion scope:
+ *
+ * ```js
+ * transcludedContent.remove();
+ * transclusionScope.$destroy();
+ * ```
+ *
+ *
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+ * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+ * then you are also responsible for calling `$destroy` on the transclusion scope.
+ *
+ *
+ * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+ * automatically destroy their transluded clones as necessary so you do not need to worry about this if
+ * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+ *
+ *
+ * #### Transclusion Scopes
+ *
+ * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+ * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+ * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+ * was taken.
+ *
+ * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+ * like this:
+ *
+ * ```html
+ *
+ * ```
+ *
+ * The `$parent` scope hierarchy will look like this:
+ *
+ * ```
+ * - $rootScope
+ * - isolate
+ * - transclusion
+ * ```
+ *
+ * but the scopes will inherit prototypically from different scopes to their `$parent`.
+ *
+ * ```
+ * - $rootScope
+ * - transclusion
+ * - isolate
+ * ```
+ *
+ *
+ * ### Attributes
+ *
+ * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+ * `link()` or `compile()` functions. It has a variety of uses.
+ *
+ * accessing *Normalized attribute names:*
+ * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.
+ * the attributes object allows for normalized access to
+ * the attributes.
+ *
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
+ * object which allows the directives to use the attributes object as inter directive
+ * communication.
+ *
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+ * allowing other directives to read the interpolated value.
+ *
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+ * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+ * the only way to easily get the actual value because during the linking phase the interpolation
+ * hasn't been evaluated yet and so the value is at this time set to `undefined`.
+ *
+ * ```js
+ * function linkingFn(scope, elm, attrs, ctrl) {
+ * // get the attribute value
+ * console.log(attrs.ngModel);
+ *
+ * // change the attribute
+ * attrs.$set('ngModel', 'new value');
+ *
+ * // observe changes to interpolated attribute
+ * attrs.$observe('ngModel', function(value) {
+ * console.log('ngModel has changed value to ' + value);
+ * });
+ * }
+ * ```
+ *
+ * ## Example
+ *
+ *
+ * **Note**: Typically directives are registered with `module.directive`. The example below is
+ * to illustrate how `$compile` works.
+ *
+ *
+
+
+
+
+
+
+ it('should auto compile', function() {
+ var textarea = $('textarea');
+ var output = $('div[compile]');
+ // The initial state reads 'Hello Angular'.
+ expect(output.getText()).toBe('Hello Angular');
+ textarea.clear();
+ textarea.sendKeys('{{name}}!');
+ expect(output.getText()).toBe('Angular!');
+ });
+
+
+
+ *
+ *
+ * @param {string|DOMElement} element Element or HTML string to compile into a template function.
+ * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
+ *
+ *
+ * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
+ * e.g. will not use the right outer scope. Please pass the transclude function as a
+ * `parentBoundTranscludeFn` to the link function instead.
+ *
+ *
+ * @param {number} maxPriority only apply directives lower than given priority (Only effects the
+ * root element(s), not their children)
+ * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ * `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ * called as: {{total}}
')(scope);
+ * ```
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ * example would not point to the clone, but rather to the original template that was cloned. In
+ * this case, you can access the clone via the cloneAttachFn:
+ * ```js
+ * var templateElement = angular.element('{{total}}
'),
+ * scope = ....;
+ *
+ * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ * //attach the clone to DOM document at the right place
+ * });
+ *
+ * //now we have reference to the cloned DOM via `clonedElement`
+ * ```
+ *
+ *
+ * For information on how the compiler works, see the
+ * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

+ *
+ * @description
+ * The `$http` service is a core Angular service that facilitates communication with the remote
+ * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
+ * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
+ *
+ * For unit testing applications that use `$http` service, see
+ * {@link ngMock.$httpBackend $httpBackend mock}.
+ *
+ * For a higher level of abstraction, please check out the {@link ngResource.$resource
+ * $resource} service.
+ *
+ * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+ * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+ * it is important to familiarize yourself with these APIs and the guarantees they provide.
+ *
+ *
+ * ## General usage
+ * The `$http` service is a function which takes a single argument — a configuration object —
+ * that is used to generate an HTTP request and returns a {@link ng.$q promise}.
+ *
+ * ```js
+ * // Simple GET request example :
+ * $http.get('/someUrl').
+ * then(function(response) {
+ * // this callback will be called asynchronously
+ * // when the response is available
+ * }, function(response) {
+ * // called asynchronously if an error occurs
+ * // or server returns response with an error status.
+ * });
+ * ```
+ *
+ * ```js
+ * // Simple POST request example (passing data) :
+ * $http.post('/someUrl', {msg:'hello word!'}).
+ * then(function(response) {
+ * // this callback will be called asynchronously
+ * // when the response is available
+ * }, function(response) {
+ * // called asynchronously if an error occurs
+ * // or server returns response with an error status.
+ * });
+ * ```
+ *
+ * The response object has these properties:
+ *
+ * - **data** – `{string|Object}` – The response body transformed with the transform
+ * functions.
+ * - **status** – `{number}` – HTTP status code of the response.
+ * - **headers** – `{function([headerName])}` – Header getter function.
+ * - **config** – `{Object}` – The configuration object that was used to generate the request.
+ * - **statusText** – `{string}` – HTTP status text of the response.
+ *
+ * A response status code between 200 and 299 is considered a success status and
+ * will result in the success callback being called. Note that if the response is a redirect,
+ * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
+ * called for such responses.
+ *
+ * ## Writing Unit Tests that use $http
+ * When unit testing (using {@link ngMock ngMock}), it is necessary to call
+ * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
+ * request using trained responses.
+ *
+ * ```
+ * $httpBackend.expectGET(...);
+ * $http.get(...);
+ * $httpBackend.flush();
+ * ```
+ *
+ * ## Shortcut methods
+ *
+ * Shortcut methods are also available. All shortcut methods require passing in the URL, and
+ * request data must be passed in for POST/PUT requests.
+ *
+ * ```js
+ * $http.get('/someUrl').then(successCallback);
+ * $http.post('/someUrl', data).then(successCallback);
+ * ```
+ *
+ * Complete list of shortcut methods:
+ *
+ * - {@link ng.$http#get $http.get}
+ * - {@link ng.$http#head $http.head}
+ * - {@link ng.$http#post $http.post}
+ * - {@link ng.$http#put $http.put}
+ * - {@link ng.$http#delete $http.delete}
+ * - {@link ng.$http#jsonp $http.jsonp}
+ * - {@link ng.$http#patch $http.patch}
+ *
+ *
+ * ## Deprecation Notice
+ *
+ * The `$http` legacy promise methods `success` and `error` have been deprecated.
+ * Use the standard `then` method instead.
+ * If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
+ * `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
+ *
+ *
+ * ## Setting HTTP Headers
+ *
+ * The $http service will automatically add certain HTTP headers to all requests. These defaults
+ * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+ * object, which currently contains this default configuration:
+ *
+ * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+ * - `Accept: application/json, text/plain, * / *`
+ * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+ * - `Content-Type: application/json`
+ * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+ * - `Content-Type: application/json`
+ *
+ * To add or overwrite these defaults, simply add or remove a property from these configuration
+ * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+ * with the lowercased HTTP method name as the key, e.g.
+ * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
+ *
+ * The defaults can also be set at runtime via the `$http.defaults` object in the same
+ * fashion. For example:
+ *
+ * ```
+ * module.run(function($http) {
+ * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'
+ * });
+ * ```
+ *
+ * In addition, you can supply a `headers` property in the config object passed when
+ * calling `$http(config)`, which overrides the defaults without changing them globally.
+ *
+ * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
+ * Use the `headers` property, setting the desired header to `undefined`. For example:
+ *
+ * ```js
+ * var req = {
+ * method: 'POST',
+ * url: 'http://example.com',
+ * headers: {
+ * 'Content-Type': undefined
+ * },
+ * data: { test: 'test' }
+ * }
+ *
+ * $http(req).then(function(){...}, function(){...});
+ * ```
+ *
+ * ## Transforming Requests and Responses
+ *
+ * Both requests and responses can be transformed using transformation functions: `transformRequest`
+ * and `transformResponse`. These properties can be a single function that returns
+ * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
+ * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+ *
+ * ### Default Transformations
+ *
+ * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
+ * `defaults.transformResponse` properties. If a request does not provide its own transformations
+ * then these will be applied.
+ *
+ * You can augment or replace the default transformations by modifying these properties by adding to or
+ * replacing the array.
+ *
+ * Angular provides the following default transformations:
+ *
+ * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
+ *
+ * - If the `data` property of the request configuration object contains an object, serialize it
+ * into JSON format.
+ *
+ * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
+ *
+ * - If XSRF prefix is detected, strip it (see Security Considerations section below).
+ * - If JSON response is detected, deserialize it using a JSON parser.
+ *
+ *
+ * ### Overriding the Default Transformations Per Request
+ *
+ * If you wish override the request/response transformations only for a single request then provide
+ * `transformRequest` and/or `transformResponse` properties on the configuration object passed
+ * into `$http`.
+ *
+ * Note that if you provide these properties on the config object the default transformations will be
+ * overwritten. If you wish to augment the default transformations then you must include them in your
+ * local transformation array.
+ *
+ * The following code demonstrates adding a new response transformation to be run after the default response
+ * transformations have been run.
+ *
+ * ```js
+ * function appendTransform(defaults, transform) {
+ *
+ * // We can't guarantee that the default transformation is an array
+ * defaults = angular.isArray(defaults) ? defaults : [defaults];
+ *
+ * // Append the new transformation to the defaults
+ * return defaults.concat(transform);
+ * }
+ *
+ * $http({
+ * url: '...',
+ * method: 'GET',
+ * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
+ * return doTransform(value);
+ * })
+ * });
+ * ```
+ *
+ *
+ * ## Caching
+ *
+ * To enable caching, set the request configuration `cache` property to `true` (to use default
+ * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
+ * When the cache is enabled, `$http` stores the response from the server in the specified
+ * cache. The next time the same request is made, the response is served from the cache without
+ * sending a request to the server.
+ *
+ * Note that even if the response is served from cache, delivery of the data is asynchronous in
+ * the same way that real requests are.
+ *
+ * If there are multiple GET requests for the same URL that should be cached using the same
+ * cache, but the cache is not populated yet, only one request to the server will be made and
+ * the remaining requests will be fulfilled using the response from the first request.
+ *
+ * You can change the default cache to a new object (built with
+ * {@link ng.$cacheFactory `$cacheFactory`}) by updating the
+ * {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set
+ * their `cache` property to `true` will now use this cache object.
+ *
+ * If you set the default cache to `false` then only requests that specify their own custom
+ * cache object will be cached.
+ *
+ * ## Interceptors
+ *
+ * Before you start creating interceptors, be sure to understand the
+ * {@link ng.$q $q and deferred/promise APIs}.
+ *
+ * For purposes of global error handling, authentication, or any kind of synchronous or
+ * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+ * able to intercept requests before they are handed to the server and
+ * responses before they are handed over to the application code that
+ * initiated these requests. The interceptors leverage the {@link ng.$q
+ * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+ *
+ * The interceptors are service factories that are registered with the `$httpProvider` by
+ * adding them to the `$httpProvider.interceptors` array. The factory is called and
+ * injected with dependencies (if specified) and returns the interceptor.
+ *
+ * There are two kinds of interceptors (and two kinds of rejection interceptors):
+ *
+ * * `request`: interceptors get called with a http `config` object. The function is free to
+ * modify the `config` object or create a new one. The function needs to return the `config`
+ * object directly, or a promise containing the `config` or a new `config` object.
+ * * `requestError`: interceptor gets called when a previous interceptor threw an error or
+ * resolved with a rejection.
+ * * `response`: interceptors get called with http `response` object. The function is free to
+ * modify the `response` object or create a new one. The function needs to return the `response`
+ * object directly, or as a promise containing the `response` or a new `response` object.
+ * * `responseError`: interceptor gets called when a previous interceptor threw an error or
+ * resolved with a rejection.
+ *
+ *
+ * ```js
+ * // register the interceptor as a service
+ * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+ * return {
+ * // optional method
+ * 'request': function(config) {
+ * // do something on success
+ * return config;
+ * },
+ *
+ * // optional method
+ * 'requestError': function(rejection) {
+ * // do something on error
+ * if (canRecover(rejection)) {
+ * return responseOrNewPromise
+ * }
+ * return $q.reject(rejection);
+ * },
+ *
+ *
+ *
+ * // optional method
+ * 'response': function(response) {
+ * // do something on success
+ * return response;
+ * },
+ *
+ * // optional method
+ * 'responseError': function(rejection) {
+ * // do something on error
+ * if (canRecover(rejection)) {
+ * return responseOrNewPromise
+ * }
+ * return $q.reject(rejection);
+ * }
+ * };
+ * });
+ *
+ * $httpProvider.interceptors.push('myHttpInterceptor');
+ *
+ *
+ * // alternatively, register the interceptor via an anonymous factory
+ * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
+ * return {
+ * 'request': function(config) {
+ * // same as above
+ * },
+ *
+ * 'response': function(response) {
+ * // same as above
+ * }
+ * };
+ * });
+ * ```
+ *
+ * ## Security Considerations
+ *
+ * When designing web applications, consider security threats from:
+ *
+ * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+ * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
+ *
+ * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+ * pre-configured with strategies that address these issues, but for this to work backend server
+ * cooperation is required.
+ *
+ * ### JSON Vulnerability Protection
+ *
+ * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+ * allows third party website to turn your JSON resource URL into
+ * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
+ * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+ * Angular will automatically strip the prefix before processing it as JSON.
+ *
+ * For example if your server needs to return:
+ * ```js
+ * ['one','two']
+ * ```
+ *
+ * which is vulnerable to attack, your server can return:
+ * ```js
+ * )]}',
+ * ['one','two']
+ * ```
+ *
+ * Angular will strip the prefix, before processing the JSON.
+ *
+ *
+ * ### Cross Site Request Forgery (XSRF) Protection
+ *
+ * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which
+ * an unauthorized site can gain your user's private data. Angular provides a mechanism
+ * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
+ * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
+ * JavaScript that runs on your domain could read the cookie, your server can be assured that
+ * the XHR came from JavaScript running on your domain. The header will not be set for
+ * cross-domain requests.
+ *
+ * To take advantage of this, your server needs to set a token in a JavaScript readable session
+ * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+ * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+ * that only JavaScript running on your domain could have sent the request. The token must be
+ * unique for each user and must be verifiable by the server (to prevent the JavaScript from
+ * making up its own tokens). We recommend that the token is a digest of your site's
+ * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
+ * for added security.
+ *
+ * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
+ * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
+ * or the per-request config object.
+ *
+ * In order to prevent collisions in environments where multiple Angular apps share the
+ * same domain or subdomain, we recommend that each application uses unique cookie name.
+ *
+ * @param {object} config Object describing the request to be made and how it should be
+ * processed. The object has following properties:
+ *
+ * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+ * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+ * - **params** – `{Object.}` – Map of strings or objects which will be serialized
+ * with the `paramSerializer` and appended as GET parameters.
+ * - **data** – `{string|Object}` – Data to be sent as the request message data.
+ * - **headers** – `{Object}` – Map of strings or functions which return strings representing
+ * HTTP headers to send to the server. If the return value of a function is null, the
+ * header will not be sent. Functions accept a config object as an argument.
+ * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+ * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+ * - **transformRequest** –
+ * `{function(data, headersGetter)|Array.}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * request body and headers and returns its transformed (typically serialized) version.
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
+ * Overriding the Default Transformations}
+ * - **transformResponse** –
+ * `{function(data, headersGetter, status)|Array.}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * response body, headers and status and returns its transformed (typically deserialized) version.
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
+ * Overriding the Default TransformationjqLiks}
+ * - **paramSerializer** - `{string|function(Object):string}` - A function used to
+ * prepare the string representation of request parameters (specified as an object).
+ * If specified as string, it is interpreted as function registered with the
+ * {@link $injector $injector}, which means you can create your own serializer
+ * by registering it as a {@link auto.$provide#service service}.
+ * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
+ * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
+ * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+ * GET request, otherwise if a cache instance built with
+ * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
+ * caching.
+ * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+ * that should abort the request when resolved.
+ * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
+ * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
+ * for more information.
+ * - **responseType** - `{string}` - see
+ * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
+ *
+ * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
+ * when the request succeeds or fails.
+ *
+ *
+ * @property {Array.} pendingRequests Array of config objects for currently pending
+ * requests. This is primarily meant to be used for debugging purposes.
+ *

+ * Compiles a string with markup into an interpolation function. This service is used by the
+ * HTML {@link ng.$compile $compile} service for data binding. See
+ * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
+ * interpolation markup.
+ *
+ *
+ * ```js
+ * var $interpolate = ...; // injected
+ * var exp = $interpolate('Hello {{name | uppercase}}!');
+ * expect(exp({name:'Angular'}).toEqual('Hello ANGULAR!');
+ * ```
+ *
+ * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
+ * `true`, the interpolation function will return `undefined` unless all embedded expressions
+ * evaluate to a value other than `undefined`.
+ *
+ * ```js
+ * var $interpolate = ...; // injected
+ * var context = {greeting: 'Hello', name: undefined };
+ *
+ * // default "forgiving" mode
+ * var exp = $interpolate('{{greeting}} {{name}}!');
+ * expect(exp(context)).toEqual('Hello !');

+ * exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
+ * expect(exp(context)).toBeUndefined();
+ * context.name = 'Angular';
+ * expect(exp(context)).toEqual('Hello Angular!');
+ * ```
+ *
+ * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
+ *
+ * ####Escaped Interpolation
+ * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+ * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+ * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+ * or binding.
+ *
+ * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+ * degree, while also enabling code examples to work without relying on the
+ * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+ *
+ * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+ * replacing angle brackets (<, >) with < and > respectively, and replacing all
+ * interpolation start/end markers with their escaped counterparts.**
+ *
+ * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+ * output when the $interpolate service processes the text. So, for HTML elements interpolated
+ * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+ * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+ * this is typically useful only when user-data is used in rendering a template from the server, or
+ * when otherwise untrusted data is used by a directive.
+ *
+ *
+ *
+ *
+ *
{{apptitle}}: \{\{ username = "defaced value"; \}\}
+ *
+ *
{{username}} attempts to inject code which will deface the
+ * application, but fails to accomplish their task, because the server has correctly
+ * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+ * characters.
+ *
Instead, the result of the attempted script injection is visible, and can be removed
+ * from the database by an administrator.
+ *
+ *
+ *
+ * @param {string} text The text with markup to interpolate.
+ * @param {boolean=} mustHaveExpression if set to true then the interpolation string must have
+ * embedded expression in order to return an interpolation function. Strings with no
+ * embedded expression will return null for the interpolation function.

+ * result through {@link ng.$sce#getTrusted $sce.getTrusted(interpolatedResult,
+ * trustedContext)} before returning it. Refer to the {@link ng.$sce $sce} service that

+// obtaining a reference to native JS functions such as the Function constructor.
+//
+// As an example, consider the following Angular expression:

+// {}.toString.constructor('alert("evil JS code")')
+//
+// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
+// against the expression language, but not to prevent exploits that were enabled by exposing
+// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
+// practice and therefore we are not even trying to protect against interaction with an object

+/**
+ * @ngdoc service
+ * @name $q
+ * @requires $rootScope
+ *
+ * @description
+ * A service that helps you run functions asynchronously, and use their return values (or exceptions)
+ * when they are done processing.
+ *
+ * This is an implementation of promises/deferred objects inspired by
+ * [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
+ * implementations, and the other which resembles ES6 promises to some degree.
+ *
+ * # $q constructor
+ *
+ * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
+ * function as the first argument. This is similar to the native Promise implementation from ES6 Harmony,
+ * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+ *
+ * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are
+ * available yet.
+ *
+ * It can be used like so:
+ *
+ * ```js
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ * // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ * function asyncGreet(name) {
+ * // perform some asynchronous operation, resolve or reject the promise when appropriate.
+ * return $q(function(resolve, reject) {
+ * setTimeout(function() {
+ * if (okToGreet(name)) {
+ * resolve('Hello, ' + name + '!');
+ * } else {
+ * reject('Greeting ' + name + ' is not allowed.');
+ * }
+ * }, 1000);
+ * });
+ * }
+ *
+ * var promise = asyncGreet('Robin Hood');
+ * promise.then(function(greeting) {
+ * alert('Success: ' + greeting);
+ * }, function(reason) {
+ * alert('Failed: ' + reason);
+ * });
+ * ```
+ *
+ * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
+ *
+ * However, the more traditional CommonJS-style usage is still available, and documented below.
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * ```js
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ * // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ * function asyncGreet(name) {
+ * var deferred = $q.defer();
+ *
+ * setTimeout(function() {
+ * deferred.notify('About to greet ' + name + '.');
+ *
+ * if (okToGreet(name)) {
+ * deferred.resolve('Hello, ' + name + '!');
+ * } else {
+ * deferred.reject('Greeting ' + name + ' is not allowed.');
+ * }
+ * }, 1000);
+ *
+ * return deferred.promise;
+ * }
+ *
+ * var promise = asyncGreet('Robin Hood');
+ * promise.then(function(greeting) {
+ * alert('Success: ' + greeting);
+ * }, function(reason) {
+ * alert('Failed: ' + reason);
+ * }, function(update) {
+ * alert('Got notification: ' + update);
+ * });
+ * ```
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of guarantees that promise and deferred APIs make, see
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
+ * of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ * constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ * resolving it with a rejection constructed via `$q.reject`.
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+ * multiple times before the promise is either resolved or rejected.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
+ * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+ * as soon as the result is available. The callbacks are called with a single argument: the result
+ * or rejection reason. Additionally, the notify callback may be called zero or more times to
+ * provide a progress indication, before the promise is resolved or rejected.
+ *
+ * This method *returns a new promise* which is resolved or rejected via the return value of the
+ * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
+ * with the value which is resolved in that promise using
+ * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
+ * It also notifies via the return value of the `notifyCallback` method. The promise cannot be
+ * resolved or rejected from the notifyCallback method.
+ *
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+ *
+ * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
+ * but to do so without modifying the final value. This is useful to release resources or do some
+ * clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+ * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+ * more information.
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
+ * possible to create a chain of promises:
+ *
+ * ```js
+ * promiseB = promiseA.then(function(result) {
+ * return result + 1;
+ * });
+ *
+ * // promiseB will be resolved immediately after promiseA is resolved and its value
+ * // will be the result of promiseA incremented by 1
+ * ```
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ * There are two main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+ * mechanism in angular, which means faster propagation of resolution or rejection into your
+ * models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+ * all the important functionality needed for common async tasks.
+ *
+ * # Testing
+ *
+ * ```js
+ * it('should simulate promise', inject(function($q, $rootScope) {
+ * var deferred = $q.defer();
+ * var promise = deferred.promise;
+ * var resolvedValue;
+ *
+ * promise.then(function(value) { resolvedValue = value; });
+ * expect(resolvedValue).toBeUndefined();
+ *
+ * // Simulate resolving of promise
+ * deferred.resolve(123);
+ * // Note that the 'then' function does not get called synchronously.
+ * // This is because we want the promise API to always be async, whether or not
+ * // it got called synchronously or asynchronously.
+ * expect(resolvedValue).toBeUndefined();
+ *
+ * // Propagate promise resolution to 'then' functions using $apply().
+ * $rootScope.$apply();
+ * expect(resolvedValue).toEqual(123);
+ * }));
+ * ```
+ *
+ * @param {function(function, function)} resolver Function which is responsible for resolving or
+ * rejecting the newly created promise. The first parameter is a function which resolves the
+ * promise, the second parameter is a function which rejects the promise.
+ *
+ * @returns {Promise} The newly created promise.

+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ * - No closures, instead use prototypical inheritance for API
+ * - Internal state needs to be stored on scope directly, which means that private state is
+ * exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ * - this means that in order to keep the same order of execution as addition we have to add
+ * items to the array at the beginning (unshift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ * - Using an array would be slow since inserts in middle are expensive so we use linked list
+ *
+ * There are few watches then a lot of observers. This is why you don't want the observer to be
+ * implemented in the same way as watch. Watch requires return of initialization function which
+ * are expensive to construct.

+ * @ngdoc method

+ * @kind function
+ *
+ * @description
+ * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
+ *
+ * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
+ * $digest()} and should return the value that will be watched. (Since
+ * {@link ng.$rootScope.Scope#$digest $digest()} reruns when it detects changes the
+ * `watchExpression` can execute multiple times per
+ * {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
+ * - The `listener` is called only when the value from the current `watchExpression` and the
+ * previous call to `watchExpression` are not equal (with the exception of the initial run,
+ * see below). Inequality is determined according to reference inequality,
+ * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
+ * via the `!==` Javascript operator, unless `objectEquality == true`
+ * (see next point)
+ * - When `objectEquality == true`, inequality of the `watchExpression` is determined
+ * according to the {@link angular.equals} function. To save the value of the object for
+ * later comparison, the {@link angular.copy} function is used. This therefore means that
+ * watching complex objects will have adverse memory and performance implications.
+ * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+ * This is achieved by rerunning the watchers until no changes are detected. The rerun
+ * iteration limit is 10 to prevent an infinite loop deadlock.
+ *
+ *
+ * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+ * you can register a `watchExpression` function with no `listener`. (Be prepared for
+ * multiple calls to your `watchExpression` because it will execute multiple times in a
+ * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
+ *
+ * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+ * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+ * watcher. In rare cases, this is undesirable because the listener is called when the result
+ * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+ * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+ * listener was called due to initialization.
+ *
+ *
+ *
+ * # Example
+ * ```js
+ // let's assume that scope was dependency injected as the $rootScope

+ * @kind function
+ *
+ * @description
+ * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
+ * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
+ * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
+ * until no more listeners are firing. This means that it is possible to get into an infinite
+ * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
+ * iterations exceeds 10.
+ *
+ * Usually, you don't call `$digest()` directly in
+ * {@link ng.directive:ngController controllers} or in
+ * {@link ng.$compileProvider#directive directives}.
+ * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
+ * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
+ *
+ * If you want to be notified whenever `$digest()` is called,
+ * you can register a `watchExpression` function with
+ * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
+ *
+ * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
+ *
+ * # Example
+ * ```js
+ var scope = ...;
+ scope.name = 'misko';
+ scope.counter = 0;
+
+ expect(scope.counter).toEqual(0);
+ scope.$watch('name', function(newValue, oldValue) {

+ * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict

+ *
+ * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
+ * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is
+ * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to

+ * work because `$sce` delegates to `$sceDelegate` for these operations.
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
+ *
+ * The default instance of `$sceDelegate` should work out of the box with little pain. While you
+ * can override it completely to change the behavior of `$sce`, the common case would
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
+ * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
+ * templates. Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
+ * $sceDelegateProvider.resourceUrlWhitelist} and {@link
+ * ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}
+ */
+
+/**
+ * @ngdoc provider
+ * @name $sceDelegateProvider
+ * @description
+ *
+ * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
+ * $sceDelegate} service. This allows one to get/set the whitelists and blacklists used to ensure
+ * that the URLs used for sourcing Angular templates are safe. Refer {@link
+ * ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist} and
+ * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}
+ *
+ * For the general details about this service in Angular, read the main page for {@link ng.$sce
+ * Strict Contextual Escaping (SCE)}.
+ *
+ * **Example**: Consider the following case. to learn more about them.
+ * You can ensure your document is in standards mode and not quirks mode by adding ``
+ * to the top of your HTML document.
+ *
+ * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * ```
+ *
+ * ```
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
+ * bindings. (HTML is just one example of a context where rendering user controlled input creates
+ * security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?) How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
+ * determine that something explicitly says it's safe to use a value for binding in that
+ * context. You can then audit your code (a simple grep would do) to ensure that this is only done
+ * for those values that you can easily tell are safe - because they were received from your server,
+ * sanitized by your library, etc. You can organize your codebase to help with this - perhaps
+ * allowing only the files in a specific directory to do this. Ensuring that the internal API
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+ * obtain values that will be accepted by SCE / privileged contexts.
+ *
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
+ * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
+ * simplified):
+ *
+ * ```
+ * var ngBindHtmlDirective = ['$sce', function($sce) {
+ * return function(scope, element, attr) {
+ * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ * element.html(value || '');
+ * });
+ * };
+ * }];
+ * ```
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
+ * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded. This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
+ * `
`) just works.
+ *
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document. You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ *
+ *
+ *
+ *
+ *
User comments
+ * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
+ * $sanitize is available. If $sanitize isn't available, this results in an error instead of an
+ * exploit.
+ *
+ *
+ * {{userComment.name}} :
+ *
+ *
+ *
+ *
+ *
+ *
+ * angular.module('mySceApp', ['ngSanitize'])
+ * .controller('AppController', ['$http', '$templateCache', '$sce',
+ * function($http, $templateCache, $sce) {
+ * var self = this;
+ * $http.get("test_data.json", {cache: $templateCache}).success(function(userComments) {
+ * self.userComments = userComments;
+ * });
+ * self.explicitlyTrustedHtml = $sce.trustAsHtml(
+ * 'Hover over this text. ');
+ * }]);
+ *
+ *
+ *
+ * [
+ * { "name": "Alice",
+ * "htmlComment":
+ * "Is anyone reading this? "
+ * },
+ * { "name": "Bob",
+ * "htmlComment": "Yes! Am I the only other one?"
+ * }

+ * expect(element(by.id('explicitlyTrustedHtml')).getInnerHtml()).toBe(
+ * 'Hover over this text. ');
+ * });
+ * });
+ *
+ *
+ *
+ *
+ *
+ * ## Can I disable SCE completely?
+ *
+ * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
+ * for little coding overhead. It will be much harder to take an SCE disabled application and
+ * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
+ * you're migrating them a module at a time.
+ *
+ * That said, here's how you can completely disable SCE:
+ *
+ * ```
+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+ * // Completely disable SCE. For demonstration purposes only!

+ /* Design notes on the default implementation for SCE.
+ *
+ * The API contract for the SCE delegate
+ * -------------------------------------
+ * The SCE delegate object must provide the following 3 methods:
+ *
+ * - trustAs(contextEnum, value)
+ * This method is used to tell the SCE service that the provided value is OK to use in the
+ * contexts specified by contextEnum. It must return an object that will be accepted by
+ * getTrusted() for a compatible contextEnum and return this value.
+ *
+ * - valueOf(value)
+ * For values that were not produced by trustAs(), return them as is. For values that were
+ * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
+ * trustAs is wrapping the given values into some type, this operation unwraps it when given
+ * such a value.
+ *
+ * - getTrusted(contextEnum, value)
+ * This function should return the a value that is safe to use in the context specified by
+ * contextEnum or throw and exception otherwise.
+ *
+ * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+ * opaque or wrapped in some holder object. That happens to be an implementation detail. For
+ * instance, an implementation could maintain a registry of all trusted objects by context. In
+ * such a case, trustAs() would return the same object that was passed in. getTrusted() would
+ * return the same object passed in if it was found in the registry under a compatible context or
+ * throw an exception otherwise. An implementation might only wrap values some of the time based
+ * on some criteria. getTrusted() might return a value and not throw an exception for special
+ * constants or objects even if not wrapped. All such implementations fulfill this contract.
+ *
+ *
+ * A note on the inheritance model for SCE contexts
+ * ------------------------------------------------
+ * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
+ * is purely an implementation details.
+ *
+ * The contract is simply this:
+ *
+ * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+ * will also succeed.
+ *
+ * Inheritance happens to capture this in a natural way. In some future, we
+ * may not use inheritance anymore. That is OK because no code outside of
+ * sce.js and sceSpecs.js would need to be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL. Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL. This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers. However, the parsed components will not be set if the URL assigned did not specify
+ * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
+ * properties such as protocol, hostname, port, etc.

+ * @ngdoc filter
+ * @name filter
+ * @kind function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ * `array`.
+ *
+ * Can be one of:
+ *
+ * - `string`: The string is used for matching against the contents of the `array`. All strings or
+ * objects with string properties in `array` that match this string will be returned. This also
+ * applies to nested object properties.
+ * The predicate can be negated by prefixing the string with `!`.
+ *
+ * - `Object`: A pattern object can be used to filter specific properties on objects contained
+ * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ * which have property `name` containing "M" and property `phone` containing "1". A special
+ * property name `$` can be used (as in `{$:"text"}`) to accept a match against any
+ * property of the object or its nested object properties. That's equivalent to the simple
+ * substring match with a `string` as described above. The predicate can be negated by prefixing
+ * the string with `!`.
+ * For example `{name: "!M"}` predicate will return an array of items which have property `name`
+ * not containing "M".
+ *
+ * Note that a named property will match properties on the same level only, while the special
+ * `$` property will match properties on the same level or deeper. E.g. an array item like
+ * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
+ * **will** be matched by `{$: 'John'}`.
+ *
+ * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
+ * The function is called for each element of the array, with the element, its index, and
+ * the entire array itself as arguments.
+ *
+ * The final result is an array of those elements that the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
+ * determining if the expected value (from the filter expression) and actual value (from
+ * the object in the array) should be considered a match.
+ *
+ * Can be one of:
+ *
+ * - `function(actual, expected)`:
+ * The function will be given the object value and the predicate value to compare and
+ * should return true if both values should be considered equal.
+ *
+ * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
+ * This is essentially strict comparison of expected and actual.
+ *
+ * - `false|undefined`: A short hand for a function which will look for a substring match in case
+ * insensitive way.
+ *
+ * Primitive values are converted to strings. Objects are not compared against primitives,
+ * unless they have a custom `toString` method (e.g. `Date` objects).
+ *
+ * @example
+
+
+
+
+ Search:
+
+ Name Phone
+ {{friend.name}}
+ {{friend.phone}}
+
+
+ Any: Name only Phone only Equality
+ Name Phone
+ {{friendObj.name}}
+ {{friendObj.phone}}

+ });

+ * @ngdoc filter
+ * @name orderBy
+ * @kind function
+ *
+ * @description
+ * Orders a specified `array` by the `expression` predicate. It is ordered alphabetically
+ * for strings and numerically for numbers. Note: if you notice numbers are not being sorted
+ * as expected, make sure they are actually being saved as numbers and not strings.
+ *
+ * @param {Array} array The array to sort.
+ * @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be
+ * used by the comparator to determine the order of elements.
+ *
+ * Can be one of:
+ *
+ * - `function`: Getter function. The result of this function will be sorted using the
+ * `<`, `===`, `>` operator.
+ * - `string`: An Angular expression. The result of this expression is used to compare elements
+ * (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by
+ * 3 first characters of a property called `name`). The result of a constant expression
+ * is interpreted as a property name to be used in comparisons (for example `"special name"`
+ * to sort object by the value of their `special name` property). An expression can be
+ * optionally prefixed with `+` or `-` to control ascending or descending sort order
+ * (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array
+ * element itself is used to compare where sorting.
+ * - `Array`: An array of function or string predicates. The first predicate in the array
+ * is used for sorting, but when two items are equivalent, the next predicate is used.
+ *
+ * If the predicate is missing or empty then it defaults to `'+'`.
+ *
+ * @param {boolean=} reverse Reverse the order of the array.
+ * @returns {Array} Sorted copy of the source array.
+ *
+ *
+ * @example
+ * The example below demonstrates a simple ngRepeat, where the data is sorted
+ * by age in descending order (predicate is set to `'-age'`).
+ * `reverse` is not set, which means it defaults to `false`.
+
+
+
+
+
+
+ Name
+ Phone Number
+ Age
+
+
+ {{friend.name}}
+ {{friend.phone}}
+ {{friend.age}}
+
+
+
+
+ *
+ * The predicate and reverse parameters can be controlled dynamically through scope properties,
+ * as shown in the next example.
+ * @example
+
+
+
+
+
+
Sorting predicate = {{predicate}}; reverse = {{reverse}}
+
+ [
unsorted ]
+
+
+
+ Name
+
+
+ Phone Number
+
+
+ Age
+
+
+
+ {{friend.name}}
+ {{friend.phone}}
+ {{friend.age}}
+
+
+
+
+ *
+ * It's also possible to call the orderBy filter manually, by injecting `$filter`, retrieving the
+ * filter routine with `$filter('orderBy')`, and calling the returned filter routine with the
+ * desired parameters.
+ *
+ * Example:
+ *
+ * @example
+
+
+
+
+
+
