Also known as aliasing, this feature has been deprecated in the Closure Compiler since its + * initial release, where it is unavailable from the CLI. The Closure Compiler allows one to log and + * influence this process. In contrast, this implementation does not introduce + * any variable declarations in global code and derives String values from + * identifier names used as property accessors.

+ *

Consolidating literals may worsen the data compression ratio when an encoding + * transformation is applied. For instance, jQuery 1.7.1 takes 248235 bytes. + * Building it with + * UglifyJS v1.2.5 results in 93647 bytes (37.73% of the original) which are + * then compressed to 33154 bytes (13.36% of the original) using gzip(1). Building it with the same + * version of UglifyJS 1.2.5 patched with the implementation of consolidation + * results in 80784 bytes (a decrease of 12863 bytes, i.e. 13.74%, in comparison + * to the aforementioned 93647 bytes) which are then compressed to 34013 bytes + * (an increase of 859 bytes, i.e. 2.59%, in comparison to the aforementioned + * 33154 bytes).

+ *

Written in the strict variant + * of ECMA-262 5.1 Edition. Encoded in UTF-8. Follows Revision 2.28 of the Google JavaScript Style Guide (except for the + * discouraged use of the {@code function} tag and the {@code namespace} tag). + * 100% typed for the Closure Compiler Version 1741.

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`. + * + * **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)` – regardless of when the promise was or will be resolved + * or rejected 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. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback` or `errorCallback`. + * + * + * # Chaining promises + * + * Because calling `then` api of a promise returns a new derived promise, it is easily possible + * to create a chain of promises: + * + * 
+ *   promiseB = promiseA.then(function(result) {

+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and it's 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.

While for simple usage patters this doesn't matter much, for advanced usage, + * it is important to familiarize yourself with these apis and 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} + * with two $http specific methods: `success` and `error`. + * + *

+     *
+ * + * Since the returned value of calling the $http function is a Promise object, you can also use + * the `then` method to register callbacks, and these callbacks will receive a single argument – + * an object representing the response. See the api signature and type info below for more + * details. + * + * + * # Shortcut methods + * + * Since all invocation of the $http service require definition of the http method and url and + * POST and PUT requests require response body/data to be provided as well, shortcut methods + * were created to simplify using the api: + * + * 
+     *   $http.get('/someUrl').success(successCallback);
+     *   $http.post('/someUrl', data).success(successCallback);
+     *
+ * + * Complete list of shortcut methods: + * + * - {@link ng.$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} + * + * + * # 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: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - `Accept: application/json, text/plain, * / *` + * - `X-Requested-With: XMLHttpRequest` + * - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from this configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with name equal to the lower-cased http method name, e.g. + * `$httpProvider.defaults.headers.get['My-Header']='value'`. + * + * Additionally, the defaults can be set at runtime via the `$http.defaults` object in a similar + * fassion as described above. + * + * + * # Transforming Requests and Responses + * + * Both requests and responses can be transformed using transform functions. By default, Angular + * applies these transformations: + * + * Request transformations: + * + * - if the `data` property of the request config object contains an object, serialize it into + * JSON format. + * + * Response transformations: + * + * - if XSRF prefix is detected, strip it (see Security Considerations section below) + * - if json response is detected, deserialize it using a JSON parser + * + * To override these transformation locally, specify transform functions as `transformRequest` + * and/or `transformResponse` properties of the config object. To globally override the default + * transforms, override the `$httpProvider.defaults.transformRequest` and + * `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`. + * + * + * # Caching + * + * To enable caching set the configuration property `cache` to `true`. When the cache is + * enabled, `$http` stores the response from the server in local cache. Next time the + * response is served from the cache without sending a request to the server. + * + * Note that even if the response is served from cache, delivery of the data is asynchronous in + * the same way that real requests are. + * + * If there are multiple GET requests for the same url that should be cached using the same + * cache, but the cache is not populated yet, only one request to the server will be made and + * the remaining requests will be fulfilled using the response for the first request. + * + * + * # Response interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication or any kind of synchronous or + * asynchronous preprocessing of received responses, it is desirable to be able to intercept + * responses for http requests before they are handed over to the application code that + * initiated these requests. The response interceptors leverage the {@link ng.$q + * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing. + * + * The interceptors are service factories that are registered with the $httpProvider by + * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor — a function that + * takes a {@link ng.$q promise} and returns the original or a new promise. + * + * 
+     *   // register the interceptor as a service
+     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+     *     return function(promise) {
+     *       return promise.then(function(response) {

+ * + * + * # Security Considerations + * + * When designing web applications, consider security threats from: + * + * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx + * JSON Vulnerability} + * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} + * + * 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 {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx + * JSON Vulnerability} allows third party web-site to turn your JSON resource URL into + * {@link http://en.wikipedia.org/wiki/JSON#JSONP 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: + * 
+     * ['one','two']
+     *
+ * + * which is vulnerable to attack, your server can return: + * 
+     * )]}',
+     * ['one','two']
+     *
+ * + * Angular will strip the prefix, before processing the JSON. + * + * + * ## Cross Site Request Forgery (XSRF) Protection + * + * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which + * an unauthorized site can gain your user's private data. Angular provides following mechanism + * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie + * called `XSRF-TOKEN` and sets it as the 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. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET 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 read the token. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript making + * up its own tokens). We recommend that the token is a digest of your site's authentication + * cookie with {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}. + * + * + * @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 turned to + * `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server. + * - **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. + * - **transformResponse** – `{function(data, headersGetter)|Array.}` – + * transform function or an array of such functions. The transform function takes the http + * response body and headers and returns its transformed (typically deserialized) version. + * - **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 $cacheFactory}, this cache will be used for + * caching. + * - **timeout** – `{number}` – timeout in milliseconds. + * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the + * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 + * requests with credentials} for more information. + * + * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the + * standard `then` method and two http specific methods: `success` and `error`. The `then` + * method takes two arguments a success and an error callback which will be called with a + * response object. The `success` and `error` methods take a single argument - a function that + * will be called when the request succeeds or fails respectively. The arguments passed into + * these functions are destructured representation of the response object passed into the + * `then` method. 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. + * + * @property {Array.} pendingRequests Array of config objects for currently pending + * requests. This is primarily meant to be used for debugging purposes. + * + * + * @example + + +
+ + +
+ + + + 
http status code: {{status}}

+ * @ngdoc directive
+ * @name ng.directive:ngCloak
+ *
+ * @description
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
+ *
+ * The directive can be applied to the `` element, but typically a fine-grained application is
+ * prefered in order to benefit from progressive rendering of the browser view.
+ *
+ * `ngCloak` works in cooperation with a css rule that is embedded within `angular.js` and
+ *  `angular.min.js` files. Following is the css rule:
+ *
+ * 
+ * [ng\:cloak], [ng-cloak], .ng-cloak {
+ *   display: none;
+ * }
+ * 

+ *
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive
+ * during the compilation of the template it deletes the `ngCloak` element attribute, which
+ * makes the compiled element visible.
+ *
+ * For the best result, `angular.js` script must be loaded in the head section of the html file;
+ * alternatively, the css rule (above) must be included in the external stylesheet of the
+ * application.
+ *
+ * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
+ * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
+ * class `ngCloak` in addition to `ngCloak` directive as shown in the example below.
+ *

+ * @description
+ * The `ngController` directive assigns behavior to a scope. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
+ *
+ * MVC components in angular:
+ *
+ * * Model — The Model is data in scope properties; scopes are attached to the DOM.
+ * * View — The template (HTML with data bindings) is rendered into the View.
+ * * Controller — The `ngController` directive specifies a Controller class; the class has
+ *   methods that typically express the business logic behind the application.
+ *
+ * Note that an alternative way to define controllers is via the `{@link ng.$route}`
+ * service.
+ *
+ * @element ANY
+ * @scope
+ * @param {expression} ngController Name of a globally accessible constructor function or an
+ *     {@link guide/expression expression} that on the current scope evaluates to a

+ *
+ * @example
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the controller (see source tab). These methods can
+ * easily be called from the angular markup. Notice that the scope becomes the `this` for the
+ * controller's instance. This allows for easy access to the view data from the controller. Also
+ * notice that any changes to the data are automatically reflected in the View without the need
+ * for a manual update.

+ * @ngdoc directive
+ * @name ng.directive:ngPluralize
+ * @restrict EA
+ *
+ * @description
+ * # Overview
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js and the rules can be overridden
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
+ * by specifying the mappings between
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} in Angular's default en-US locale: "one" and "other".
+ *
+ * While a pural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. You will see the use of plural categories
+ * and explicit number rules throughout later parts of this documentation.
+ *
+ * # Configuring ngPluralize
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
+ * Angular expression}; these are evaluated on the current scope for its bound value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object so that Angular
+ * can interpret it correctly.
+ *
+ * The following example shows how to configure ngPluralize:
+ *
+ * 
+ * 
+ * 
+ *

+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * `{{personCount}}`. The closed braces `{}` is a placeholder
+ * for {{numberExpression}}.
+ *
+ * # Configuring ngPluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * 
+ * 
+ * 
+ * 

+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bounded to.
+ * @param {string} when The mapping between plural category to its correspoding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *

+ * @ngdoc directive
+ * @name ng.directive:ngRepeat
+ *
+ * @description
+ * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
+ * instance gets its own scope, where the given loop variable is set to the current collection item,
+ * and `$index` is set to the item index or key.
+ *
+ * Special properties are exposed on the local scope of each template instance, including:
+ *
+ *   * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
+ *   * `$first` – `{boolean}` – true if the repeated element is first in the iterator.
+ *   * `$middle` – `{boolean}` – true if the repeated element is between the first and last in the iterator.
+ *   * `$last` – `{boolean}` – true if the repeated element is last in the iterator.
+ *
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. Two
+ *   formats are currently supported:
+ *
+ *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+ *     is a scope expression giving the collection to enumerate.
+ *
+ *     For example: `track in cd.tracks`.
+ *
+ *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ *     and `expression` is the scope expression giving the collection to enumerate.
+ *
+ *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ * @example
+ * This example initializes the scope to a list of names and
+ * then uses `ngRepeat` to display every person:
+    
+      
+        

+          I have {{friends.length}} friends. They are:

+ * `ngView` is a directive that complements the {@link ng.$route $route} service by
+ * including the rendered template of the current route into the main layout (`index.html`) file.
+ * Every time the current route changes, the included view changes with it according to the
+ * configuration of the `$route` service.
