+ * - The `listener` is called whenever anything within the `obj` has changed. Examples include
+ * adding, removing, and moving items belonging to an object or array.

+ *
+ * @example
+ * ```js

+ * @param {function(newCollection, oldCollection, scope)} listener a callback function called
+ * when a change is detected.
+ * - The `newCollection` object is the newly modified data obtained from the `obj` expression
+ * - The `oldCollection` object is a copy of the former collection data.

+ * @description
+ *
+ * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
+ * Contextual Escaping (SCE)} services to AngularJS.
+ *
+ * For an overview of this service and the functionnality it provides in AngularJS, see the main
+ * page for {@link ng.$sce SCE}. The current page is targeted for developers who need to alter how
+ * SCE works in their application, which shouldn't be needed in most cases.
+ *
+ *
+ * AngularJS strongly relies on contextual escaping for the security of bindings: disabling or
+ * modifying this might cause cross site scripting (XSS) vulnerabilities. For libraries owners,
+ * changes to this service will also influence users, so be extra careful and document your changes.
+ *
+ *
+ * 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 `$sce` provides numerous shorthand methods, etc., you really only need to
+ * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
+ * work because `$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

+ *
+ * @description
+ *
+ * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
+ * $sceDelegate service}, used as a delegate for {@link ng.$sce Strict Contextual Escaping (SCE)}.
+ *
+ * The `$sceDelegateProvider` allows one to get/set the whitelists and blacklists used to ensure
+ * that the URLs used for sourcing AngularJS templates and other script-running URLs are safe (all
+ * places that use the `$sce.RESOURCE_URL` context). See
+ * {@link ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist}
+ * and
+ * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist},
+ *
+ * For the general details about this service in AngularJS, read the main page for {@link ng.$sce
+ * Strict Contextual Escaping (SCE)}.
+ *
+ * **Example**: Consider the following case.
+ *
+ * - your app is hosted at url `http://myapp.example.com/`
+ * - but some of your templates are hosted on other domains you control such as
+ * `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
+ * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
+ *
+ * Here is what a secure configuration for this scenario might look like:
+ *
+ * ```
+ * angular.module('myApp', []).config(function($sceDelegateProvider) {
+ * $sceDelegateProvider.resourceUrlWhitelist([
+ * // Allow same origin resource loads.
+ * 'self',
+ * // Allow loading from our assets domain. Notice the difference between * and **.
+ * 'http://srv*.assets.example.com/**'
+ * ]);
+ *
+ * // The blacklist overrides the whitelist so the open redirect here is blocked.
+ * $sceDelegateProvider.resourceUrlBlacklist([
+ * 'http://myapp.example.com/clickThru**'
+ * ]);
+ * });
+ * ```
+ * Note that an empty whitelist will block every resource URL from being loaded, and will require
+ * you to manually mark each one as trusted with `$sce.trustAsResourceUrl`. However, templates
+ * requested by {@link ng.$templateRequest $templateRequest} that are present in
+ * {@link ng.$templateCache $templateCache} will not go through this check. If you have a mechanism
+ * to populate your templates in that cache at config time, then it is a good idea to remove 'self'
+ * from that whitelist. This helps to mitigate the security impact of certain types of issues, like
+ * for instance attacker-controlled `ng-includes`.

+ * @ngdoc service
+ * @name $sce
+ * @kind function
+ *
+ * @description
+ *
+ * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+ *
+ * ## Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
+ * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
+ * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * ### Overview
+ *
+ * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
+ * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
+ * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
+ * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
+ * can be sanitized, but template URLs cannot, for instance.
+ *
+ * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
+ * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
+ * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
+ * render the input as-is, you will need to mark it as trusted for that context before attempting
+ * to bind it.
+ *
+ * As of version 1.2, AngularJS ships with SCE enabled by default.
+ *
+ * ### In practice
+ *
+ * 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, which would
+ * be an XSS security bug. 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, AngularJS makes sure bindings go through that sanitization, or
+ * any similar validation process, unless there's a good reason to trust the given value in this
+ * context. That trust is formalized with a function call. This means that as a developer, you
+ * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
+ * you just need to ensure the values you mark as trusted indeed 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 $sce.trustAsHtml}, etc.) to
+ * build the trusted versions of your values.
+ *
+ * ### How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as
+ * a way to enforce the required security context in your data sink. Directives use {@link
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
+ * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
+ * when binding without directives, AngularJS will understand the context of your bindings
+ * automatically.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$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($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ * element.html(value || '');
+ * });
+ * };
+ * }];
+ * ```
+ *
+ * ### Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, AngularJS only loads templates from the same domain and protocol as the application
+ * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
+ * protocols, you may either {@link ng.$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 (e.g.
+ * ``) just works. The `$sceDelegate` will
+ * also use the `$sanitize` service if it is available when binding untrusted values to
+ * `$sce.HTML` context. AngularJS provides an implementation in `angular-sanitize.js`, and if you
+ * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
+ * your application.
+ *
+ * The included {@link ng.$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.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ *
+ * ### What trusted context types are supported?
+ *
+ * | Context | Notes |
+ * |---------------------|----------------|
+ * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered, and the {@link ngSanitize.$sanitize $sanitize} service is available (implemented by the {@link ngSanitize ngSanitize} module) this will sanitize the value instead of throwing an error. |
+ * | `$sce.CSS` | For CSS that's safe to source into the application. Currently, no bindings require this context. Feel free to use it in your own directives. |
+ * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does (it's not just the URL that matters, but also what is at the end of it), and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
+ * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently, no bindings require this context. Feel free to use it in your own directives. |
+ *
+ *
+ * Be aware that `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#getTrusted $sce.getTrusted}. There's no CSS-, URL-, or JS-context bindings
+ * in AngularJS currently, so their corresponding `$sce.trustAs` functions aren't useful yet. This
+ * might evolve.
+ *
+ * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist}
+ *
+ * Each element in these arrays must be one of the following:
+ *
+ * - **'self'**
+ * - The special **string**, `'self'`, can be used to match against all URLs of the **same
+ * domain** as the application document using the **same protocol**.
+ * - **String** (except the special value `'self'`)
+ * - The string is matched against the full *normalized / absolute URL* of the resource
+ * being tested (substring matches are not good enough.)
+ * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
+ * match themselves.
+ * - `*`: matches zero or more occurrences of any character other than one of the following 6
+ * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use
+ * in a whitelist.
+ * - `**`: matches zero or more occurrences of *any* character. As such, it's not
+ * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g.
+ * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+ * not have been the intention.) Its usage at the very end of the path is ok. (e.g.
+ * http://foo.example.com/templates/**).
+ * - **RegExp** (*see caveat below*)
+ * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
+ * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
+ * accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+ * have good test coverage). For instance, the use of `.` in the regex is correct only in a
+ * small number of cases. A `.` character in the regex used when matching the scheme or a
+ * subdomain could be matched against a `:` or literal `.` that was likely not intended. It
+ * is highly recommended to use the string patterns and only fall back to regular expressions
+ * as a last resort.
+ * - The regular expression must be an instance of RegExp (i.e. not a string.) It is
+ * matched against the **entire** *normalized / absolute URL* of the resource being tested
+ * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
+ * present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+ * - If you are generating your JavaScript from some other templating engine (not
+ * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+ * remember to escape your regular expression (and be aware that you might need more than
+ * one level of escaping depending on your templating engine and the way you interpolated
+ * the value.) Do make use of your platform's escaping mechanism as it might be good
+ * enough before coding your own. E.g. Ruby has
+ * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+ * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+ * Javascript lacks a similar built in function for escaping. Take a look at Google
+ * Closure library's [goog.string.regExpEscape(s)](
+ * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.
+ *
+ * ### Show me an example using SCE.
+ *

+ *
+ *
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.

+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ *
+ * **Note**: If the array contains objects that reference themselves, filtering is not possible.
+ *
+ * @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 (`$` by default) can be used (e.g. as in `{$: "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 special property name can be
+ * overwritten, using the `anyPropertyKey` parameter.
+ * 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|false} [comparator] Comparator which is used in
+ * determining if values retrieved using `expression` (when it is not a function) should be
+ * considered a match based on the expected value (from the filter expression) and actual
+ * value (from the object in the array).
+ *
+ * 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`: A short hand for a function which will look for a substring match in a 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).
+ *
+ *
+ * Defaults to `false`.
+ *
+ * @param {string} [anyPropertyKey] The special property name that matches against any property.
+ * By default `$`.

+ * (e.g. `"h 'o''clock'"`).
+ *
+ * Any other characters in the `format` string will be output as-is.
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or

+/**
+ * @ngdoc filter
+ * @name limitTo
+ * @kind function
+ *
+ * @description
+ * Creates a new array or string containing only a specified number of elements. The elements are
+ * taken from either the beginning or the end of the source array, string or number, as specified by
+ * the value and sign (positive or negative) of `limit`. Other array-like objects are also supported
+ * (e.g. array subclasses, NodeLists, jqLite/jQuery collections etc). If a number is used as input,
+ * it is converted to a string.
+ *
+ * @param {Array|ArrayLike|string|number} input - Array/array-like, string or number to be limited.
+ * @param {string|number} limit - The length of the returned array or string. If the `limit` number
+ * is positive, `limit` number of items from the beginning of the source array/string are copied.
+ * If the number is negative, `limit` number of items from the end of the source array/string
+ * are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined,
+ * the input will be returned unchanged.
+ * @param {(string|number)=} begin - Index at which to begin limitation. As a negative index,
+ * `begin` indicates an offset from the end of `input`. Defaults to `0`.
+ * @returns {Array|string} A new sub-array or substring of length `limit` or less if the input had
+ * less than `limit` elements.
+ *
+ * @example
+
+
+
+
+
+
Output numbers: {{ numbers | limitTo:numLimit }}
+
+
Output letters: {{ letters | limitTo:letterLimit }}
+
+
Output long number: {{ longNumber | limitTo:longNumberLimit }}
+
+ * (If the object has a `valueOf()` method that returns another object, then the returned object
+ * will be used in subsequent steps.)
+ * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
+ * returns a primitive, its return value will be used instead.
+ * (If the object has a `toString()` method that returns another object, then the returned object
+ * will be used in subsequent steps.)
+ * 3. No conversion; the object itself is used.
+ *
+ * ### The default comparator
+ *
+ * The default, built-in comparator should be sufficient for most usecases. In short, it compares
+ * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
+ * using their index in the original collection, and sorts values of different types by type.
+ *
+ * More specifically, it follows these steps to determine the relative order of items:
+ *
+ * 1. If the compared values are of different types, compare the types themselves alphabetically.
+ * 2. If both values are of type `string`, compare them alphabetically in a case- and
+ * locale-insensitive way.
+ * 3. If both values are objects, compare their indices instead.
+ * 4. Otherwise, return:
+ * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
+ * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
+ * - `1`, otherwise.
+ *
+ * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
+ * saved as numbers and not strings.
+ * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e.
+ * `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to
+ * other values.
+ *
+ * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
+ * @param {(Function|string|Array.)=} expression - A predicate (or list of
+ * predicates) to be used by the comparator to determine the order of elements.
+ *
+ * Can be one of:
+ *
+ * - `Function`: A getter function. This function will be called with each item as argument and
+ * the return value will be used for sorting.
+ * - `string`: An AngularJS expression. This expression will be evaluated against each item and the
+ * result will be used for sorting. For example, use `'label'` to sort by a property called
+ * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
+ * property.
+ * (The result of a constant expression is interpreted as a property name to be used for
+ * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
+ * property called `special name`.)
+ * An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
+ * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
+ * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
+ * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
+ * relative order of two items, the next predicate is used as a tie-breaker.
+ *
+ * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
+ *
+ * @param {boolean=} reverse - If `true`, reverse the sorting order.
+ * @param {(Function)=} comparator - The comparator function used to determine the relative order of
+ * value pairs. If omitted, the built-in comparator will be used.
+ *
+ * @returns {Array} - The sorted array.
+ *
+ *
+ * @example
+ * ### Ordering a table with `ngRepeat`
+ *
+ * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
+ * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
+ * it defaults to the built-in comparator.
+ *
+
+
+
+
+
+ | Name |
+ Phone Number |
+ Age |
+
+
+ | {{friend.name}} |
+ {{friend.phone}} |
+ {{friend.age}} |
+
+
+
+ *
+ * @example
+ * ### Changing parameters dynamically
+ *
+ * All parameters can be changed dynamically. The next example shows how you can make the columns of
+ * a table sortable, by binding the `expression` and `reverse` parameters to scope properties.
+ *
+
+
+
+
Sort by = {{propertyName}}; reverse = {{reverse}}
+
+
+
+
+
+ |
+
+
+ |
+
+
+
+ |
+
+
+
+ |
+
+
+ | {{friend.name}} |
+ {{friend.phone}} |
+ {{friend.age}} |
+
+
+
+ *
+ * @example
+ * ### Using `orderBy` inside a controller
+ *
+ * It is also possible to call the `orderBy` filter manually, by injecting `orderByFilter`, and
+ * calling it with the desired parameters. (Alternatively, you could inject the `$filter` factory
+ * and retrieve the `orderBy` filter with `$filter('orderBy')`.)
+ *
+
+
+
+
Sort by = {{propertyName}}; reverse = {{reverse}}
+
+
+
+
+
+ |
+
+
+ |
+
+
+
+ |
+
+
+
+ |
+
+
+ | {{friend.name}} |
+ {{friend.phone}} |
+ {{friend.age}} |
+
+
+
+ *
+ * @example
+ * ### Using a custom comparator
+ *
+ * If you have very specific requirements about the way items are sorted, you can pass your own
+ * comparator function. For example, you might need to compare some strings in a locale-sensitive
+ * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
+ * argument - passing `false` retains the default sorting order, i.e. ascending.)
+ *
