This API is used by the injector * to determine which services need to be injected into the function when the function is invoked. There are three * ways in which the function can be annotated with the needed dependencies. * * # Argument names * * The simplest form is to extract the dependencies from the arguments of the function. This is done by converting * the function into a string using `toString()` method and extracting the argument names. *

 *   function MyController($scope, $route) {
 *     // ...
 *   }
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * 
* * This method does not work with code minfication / obfuscation. For this reason the following annotation strategies * are supported. * * # The `$inject` property * * 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. *
 *   // Given
 *   var MyController = function(obfuscatedScope, obfuscatedRoute) {

 *   // Define function dependencies

 *
 *   // 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 `$inject` property is very * inconvenient. In these situations using the array notation to specify the dependencies in a way that survives * minification is a better choice: * *
 *   // We wish to write this (not minification / obfuscation safe)
 *   injector.invoke(function($compile, $rootScope) {
 *     // ...

`cloneAttachFn(clonedElement, scope)` where: * * * `clonedElement` - is a clone of the original `element` passed into the compiler. * * `scope` - is the current scope with which the linking function is working with. * * Calling the linking function returns the element of the template.

* * 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](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 `$q.defer()`. * * The purpose of the deferred object is to expose the associated Promise instance as well as APIs * that can be used for signaling the successful or unsuccessful completion of the task. * * **Methods** * * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection * constructed via `$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`. * * **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) {
 *     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 three 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 promises are recognized by the templating engine in angular, which means that in templates * you can treat promises attached to a scope as if they were the resulting values. * - Q has many more features that $q, but that comes at a cost of bytes. $q is tiny, but contains * all the important functionality needed for common async tasks. * * # Testing * *
 *    it('should simulate promise', inject(function($q, $rootScope) {

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`. * *
     *   $http({method: 'GET', url: '/someUrl'}).
     *     success(function(data, status, headers, config) {
     *       // this callback will be called asynchronously
     *       // when the response is available
     *     }).
     *     error(function(data, status, headers, config) {
     *       // called asynchronously if an error occurs
     *       // or server returns response with an error status.
     *     });
     * 
* * 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. * * A response status code that falls in the [200, 300) range 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. * * # 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) {
     *         // do something on success
     *       }, function(response) {
     *         // do something on error
     *         if (canRecover(response)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(response);
     *       });
     *     }
     *   });
     *
     *   $httpProvider.responseInterceptors.push('myHttpInterceptor');
     *
     *
     *   // register the interceptor via an anonymous factory
     *   $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
     *     return function(promise) {
     *       // same as above
     *     }

* * * # 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

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. * * @example
Person 1:
Person 2:
Number of People:
Without Offset:
With Offset(2):
