/**
* @ngdoc function
* @name ui.router.util.$resolve#resolve
* @methodOf ui.router.util.$resolve
*
* @description
* Resolves a set of invocables. An invocable is a function to be invoked via
* `$injector.invoke()`, and can have an arbitrary number of dependencies.
* An invocable can either return a value directly,
* or a `$q` promise. If a promise is returned it will be resolved and the
* resulting value will be used instead. Dependencies of invocables are resolved
* (in this order of precedence)
*
* - from the specified `locals`
* - from another invocable that is part of this `$resolve` call
* - from an invocable that is inherited from a `parent` call to `$resolve`
* (or recursively
* - from any ancestor `$resolve` of that parent).
*
* The return value of `$resolve` is a promise for an object that contains
* (in this order of precedence)
*
* - any `locals` (if specified)
* - the resolved return values of all injectables
* - any values inherited from a `parent` call to `$resolve` (if specified)
*
* The promise will resolve after the `parent` promise (if any) and all promises
* returned by injectables have been resolved. If any invocable
* (or `$injector.invoke`) throws an exception, or if a promise returned by an
* invocable is rejected, the `$resolve` promise is immediately rejected with the
* same error. A rejection of a `parent` promise (if specified) will likewise be
* propagated immediately. Once the `$resolve` promise has been rejected, no
* further invocables will be called.
*
* Cyclic dependencies between invocables are not permitted and will caues `$resolve`
* to throw an error. As a special case, an injectable can depend on a parameter
* with the same name as the injectable, which will be fulfilled from the `parent`
* injectable of the same name. This allows inherited values to be decorated.
* Note that in this case any other injectable in the same `$resolve` with the same
* dependency would see the decorated value, not the inherited value.
*
* Note that missing dependencies -- unlike cyclic dependencies -- will cause an
* (asynchronous) rejection of the `$resolve` promise rather than a (synchronous)
* exception.
*
* Invocables are invoked eagerly as soon as all dependencies are available.
* This is true even for dependencies inherited from a `parent` call to `$resolve`.
*
* As a special case, an invocable can be a string, in which case it is taken to
* be a service name to be passed to `$injector.get()`. This is supported primarily
* for backwards-compatibility with the `resolve` property of `$routeProvider`
* routes.
*
* @param {object} invocables functions to invoke or
* `$injector` services to fetch.
* @param {object} locals values to make available to the injectables

/**
* @ngdoc object
* @name ui.router.util.type:UrlMatcher
*
* @description
* Matches URLs against patterns and extracts named parameters from the path or the search
* part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
* of search parameters. Multiple search parameter names are separated by '&'. Search parameters
* do not influence whether or not a URL is matched, but their values are passed through into
* the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
*
* Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
* syntax, which optionally allows a regular expression for the parameter to be specified:
*
* * `':'` name - colon placeholder
* * `'*'` name - catch-all placeholder
* * `'{' name '}'` - curly placeholder
* * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
* regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
*
* Parameter names may contain only word characters (latin letters, digits, and underscore) and
* must be unique within the pattern (across both path and search parameters). For colon
* placeholders or curly placeholders without an explicit regexp, a path parameter matches any
* number of characters other than '/'. For catch-all placeholders the path parameter matches
* any number of characters.
*
* Examples:
*
* * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
* trailing slashes, and patterns have to match the entire path, not just a prefix.
* * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
* '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
* * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
* * `'/user/{id:[^/]*}'` - Same as the previous example.
* * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
* parameter consists of 1 to 8 hex digits.
* * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
* path into the parameter 'path'.
* * `'/files/*path'` - ditto.
* * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
* in the built-in `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
*
* @param {string} pattern The pattern to compile into a matcher.
* @param {Object} config A configuration object hash:
* @param {Object=} parentMatcher Used to concatenate the pattern/config onto
* an existing UrlMatcher
*
* * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
* * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
*
* @property {string} prefix A static prefix of this pattern. The matcher guarantees that any
* URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
* non-null) will start with this prefix.
*
* @property {string} source The pattern that was passed into the constructor
*
* @property {string} sourcePath The path portion of the source property
*
* @property {string} sourceSearch The search portion of the source property
*
* @property {string} regex The constructed regex that will be used to match against the url when
* it is time to determine which url will match.
*
* @returns {Object} New `UrlMatcher` object

* See {@link ui.router.util.type:Type `Type`} for information on the values accepted.
*
* @returns {Object} Returns `$urlMatcherFactoryProvider`.
*
* @example
* This is a simple example of a custom type that encodes and decodes items from an
* array, using the array index as the URL-encoded value:
*
* <pre>
* var list = ['John', 'Paul', 'George', 'Ringo'];

*
* // ...
*
* // Changes URL to '/list/3', logs "Ringo" to the console
* $state.go('list', { item: "Ringo" });
* </pre>
*
* This is a more complex example of a type that relies on dependency injection to
* interact with services, and uses the parameter name from the URL to infer how to
* handle encoding and decoding parameter values:
*
* <pre>
* // Defines a custom type that gets a value from a service,
* // where each service gets different types of values from
* // a backend API:
* $urlMatcherFactoryProvider.type('dbObject', {}, function(Users, Posts) {
*
* // Matches up services to URL parameter names
* var services = {
* user: Users,
* post: Posts
* };
*
* return {
* encode: function(object) {
* // Represent the object in the URL using its unique ID
* return object.id;
* },
* decode: function(value, key) {
* // Look up the object by ID, using the parameter
* // name (key) to call the correct service
* return services[key].findById(value);
* },
* is: function(object, key) {
* // Check that object is a valid dbObject
* return angular.isObject(object) && object.id && services[key];
* }
* equals: function(a, b) {
* // Check the equality of decoded objects by comparing
* // their unique IDs
* return a.id === b.id;
* }
* };
* });
*
* // In a config() block, you can then attach URLs with
* // type-annotated parameters:
* $stateProvider.state('users', {
* url: "/users",
* // ...
* }).state('users.item', {
* url: "/{user:dbObject}",

/**
* @ngdoc function
* @name ui.router.state.$stateProvider#decorator
* @methodOf ui.router.state.$stateProvider
*
* @description
* Allows you to extend (carefully) or override (at your own peril) the
* `stateBuilder` object used internally by `$stateProvider`. This can be used
* to add custom functionality to ui-router, for example inferring templateUrl
* based on the state name.
*
* When passing only a name, it returns the current (original or decorated) builder
* function that matches `name`.
*
* The builder functions that can be decorated are listed below. Though not all
* necessarily have a good use case for decoration, that is up to you to decide.
*
* In addition, users can attach custom decorators, which will generate new
* properties within the state's internal definition. There is currently no clear
* use-case for this beyond accessing internal states (i.e. $state.$current),
* however, expect this to become increasingly relevant as we introduce additional
* meta-programming features.
*
* **Warning**: Decorators should not be interdependent because the order of
* execution of the builder functions in non-deterministic. Builder functions
* should only be dependent on the state definition object and super function.
*
*
* Existing builder functions and current return values:
*
* - **parent** `{object}` - returns the parent state object.
* - **data** `{object}` - returns state data, including any inherited data that is not
* overridden by own values (if any).
* - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
* or `null`.
* - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is
* navigable).
* - **params** `{object}` - returns an array of state params that are ensured to
* be a super-set of parent's params.
* - **views** `{object}` - returns a views object where each key is an absolute view
* name (i.e. "viewName@stateName") and each value is the config object
* (template, controller) for the view. Even when you don't use the views object
* explicitly on a state config, one is still created for you internally.
* So by decorating this builder function you have access to decorating template
* and controller properties.
* - **ownParams** `{object}` - returns an array of params that belong to the state,
* not including any params defined by ancestor states.
* - **path** `{string}` - returns the full path from the root down to this state.
* Needed for state activation.
* - **includes** `{object}` - returns an object that includes every state that
* would pass a `$state.includes()` test.
*
* @example
* <pre>
* // Override the internal 'views' builder with a function that takes the state
* // definition, and a reference to the internal function being overridden:
* $stateProvider.decorator('views', function (state, parent) {
* var result = {},
* views = parent(state);
*
* angular.forEach(views, function (config, name) {
* var autoName = (state.name + '.' + name).replace('.', '/');
* config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
* result[name] = config;
* });
* return result;
* });
*
* $stateProvider.state('home', {
* views: {
* 'contact.list': { controller: 'ListController' },
* 'contact.item': { controller: 'ItemController' }
* }
* });
*
* // ...
*
* $state.go('home');
* // Auto-populates list and item views with /partials/home/contact/list.html,
* // and /partials/home/contact/item.html, respectively.
* </pre>
*
* @param {string} name The name of the builder function to decorate.
* @param {object} func A function that is responsible for decorating the original
* builder function. The function receives two parameters:
*
* - `{object}` - state - The state config object.
* - `{object}` - super - The original builder function.

/**
* @ngdoc function
* @name ui.router.state.$stateProvider#state
* @methodOf ui.router.state.$stateProvider
*
* @description
* Registers a state configuration under a given state name. The stateConfig object
* has the following acceptable properties.
*
* @param {string} name A unique state name, e.g. "home", "about", "contacts".
* To create a parent/child state use a dot, e.g. "about.sales", "home.newest".
* @param {object} stateConfig State configuration object.
* @param {string|function=} stateConfig.template
* <a id='template'></a>
* html template as a string or a function that returns
* an html template as a string which should be used by the uiView directives. This property
* takes precedence over templateUrl.
*
* If `template` is a function, it will be called with the following parameters:
*
* - {array.&lt;object&gt;} - state parameters extracted from the current $location.path() by
* applying the current state
*
* <pre>template:
* "<h1>inline template definition</h1>" +
* "<div ui-view></div>"</pre>
* <pre>template: function(params) {
* return "<h1>generated template</h1>"; }</pre>
* </div>
*
* @param {string|function=} stateConfig.templateUrl
* <a id='templateUrl'></a>
*
* path or function that returns a path to an html
* template that should be used by uiView.
*
* If `templateUrl` is a function, it will be called with the following parameters:
*
* - {array.&lt;object&gt;} - state parameters extracted from the current $location.path() by
* applying the current state
*
* <pre>templateUrl: "home.html"</pre>
* <pre>templateUrl: function(params) {
* return myTemplates[params.pageId]; }</pre>
*
* @param {function=} stateConfig.templateProvider
* <a id='templateProvider'></a>
* Provider function that returns HTML content string.
* <pre> templateProvider:
* function(MyTemplateService, params) {
* return MyTemplateService.getTemplate(params.pageId);
* }</pre>
*
* @param {string|function=} stateConfig.controller
* <a id='controller'></a>
*
* Controller fn that should be associated with newly
* related scope or the name of a registered controller if passed as a string.
* Optionally, the ControllerAs may be declared here.
* <pre>controller: "MyRegisteredController"</pre>
* <pre>controller:
* "MyRegisteredController as fooCtrl"}</pre>
* <pre>controller: function($scope, MyService) {
* $scope.data = MyService.getData(); }</pre>
*
* @param {function=} stateConfig.controllerProvider
* <a id='controllerProvider'></a>
*
* Injectable provider function that returns the actual controller or string.
* <pre>controllerProvider:
* function(MyResolveData) {
* if (MyResolveData.foo)
* return "FooCtrl"
* else if (MyResolveData.bar)
* return "BarCtrl";
* else return function($scope) {
* $scope.baz = "Qux";
* }
* }</pre>
*
* @param {string=} stateConfig.controllerAs
* <a id='controllerAs'></a>
*
* A controller alias name. If present the controller will be
* published to scope under the controllerAs name.
* <pre>controllerAs: "myCtrl"</pre>
*
* @param {object=} stateConfig.resolve
* <a id='resolve'></a>
*
* An optional map&lt;string, function&gt; of dependencies which
* should be injected into the controller. If any of these dependencies are promises,
* the router will wait for them all to be resolved before the controller is instantiated.
* If all the promises are resolved successfully, the $stateChangeSuccess event is fired
* and the values of the resolved promises are injected into any controllers that reference them.
* If any of the promises are rejected the $stateChangeError event is fired.
*
* The map object is:
*
* - key - {string}: name of dependency to be injected into controller
* - factory - {string|function}: If string then it is alias for service. Otherwise if function,
* it is injected and return value it treated as dependency. If result is a promise, it is
* resolved before its value is injected into controller.
*
* <pre>resolve: {
* myResolve1:
* function($http, $stateParams) {
* return $http.get("/api/foos/"+stateParams.fooID);
* }
* }</pre>
*
* @param {string=} stateConfig.url
* <a id='url'></a>
*
* A url fragment with optional parameters. When a state is navigated or
* transitioned to, the `$stateParams` service will be populated with any
* parameters that were passed.
*
* examples:
* <pre>url: "/home"
* url: "/users/:userid"
* url: "/books/{bookid:[a-zA-Z_-]}"
* url: "/books/{categoryid:int}"
* url: "/books/{publishername:string}/{categoryid:int}"
* url: "/messages?before&after"
* url: "/messages?{before:date}&{after:date}"</pre>
* url: "/messages/:mailboxid?{before:date}&{after:date}"
*
* @param {object=} stateConfig.views
* <a id='views'></a>
* an optional map&lt;string, object&gt; which defined multiple views, or targets views
* manually/explicitly.
*
* Examples:
*
* Targets three named `ui-view`s in the parent state's template
* <pre>views: {
* header: {
* controller: "headerCtrl",
* templateUrl: "header.html"
* }, body: {
* controller: "bodyCtrl",
* templateUrl: "body.html"
* }, footer: {
* controller: "footCtrl",
* templateUrl: "footer.html"
* }
* }</pre>
*
* Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
* <pre>views: {
* 'header@top': {
* controller: "msgHeaderCtrl",
* templateUrl: "msgHeader.html"
* }, 'body': {
* controller: "messagesCtrl",
* templateUrl: "messages.html"
* }
* }</pre>
*
* @param {boolean=} [stateConfig.abstract=false]
* <a id='abstract'></a>
* An abstract state will never be directly activated,
* but can provide inherited properties to its common children states.
* <pre>abstract: true</pre>
*
* @param {function=} stateConfig.onEnter
* <a id='onEnter'></a>
*
* Callback function for when a state is entered. Good way
* to trigger an action or dispatch an event, such as opening a dialog.
* If minifying your scripts, make sure to explictly annotate this function,
* because it won't be automatically annotated by your build tools.
*
* <pre>onEnter: function(MyService, $stateParams) {
* MyService.foo($stateParams.myParam);
* }</pre>
*
* @param {function=} stateConfig.onExit
* <a id='onExit'></a>
*
* Callback function for when a state is exited. Good way to
* trigger an action or dispatch an event, such as opening a dialog.
* If minifying your scripts, make sure to explictly annotate this function,
* because it won't be automatically annotated by your build tools.
*
* <pre>onExit: function(MyService, $stateParams) {
* MyService.cleanup($stateParams.myParam);
* }</pre>
*
* @param {boolean=} [stateConfig.reloadOnSearch=true]
* <a id='reloadOnSearch'></a>
*
* If `false`, will not retrigger the same state
* just because a search/query parameter has changed (via $location.search() or $location.hash()).
* Useful for when you'd like to modify $location.search() without triggering a reload.
* <pre>reloadOnSearch: false</pre>
*
* @param {object=} stateConfig.data
* <a id='data'></a>
*
* Arbitrary data object, useful for custom configuration. The parent state's `data` is
* prototypally inherited. In other words, adding a data property to a state adds it to
* the entire subtree via prototypal inheritance.
*
* <pre>data: {
* requiredRole: 'foo'
* } </pre>
*
* @param {object=} stateConfig.params
* <a id='params'></a>
*
* A map which optionally configures parameters declared in the `url`, or
* defines additional non-url parameters. For each parameter being
* configured, add a configuration object keyed to the name of the parameter.
*
* Each parameter configuration object may contain the following properties:
*
* - ** value ** - {object|function=}: specifies the default value for this
* parameter. This implicitly sets this parameter as optional.
*
* When UI-Router routes to a state and no value is
* specified for this parameter in the URL or transition, the
* default value will be used instead. If `value` is a function,
* it will be injected and invoked, and the return value used.
*
* *Note*: `undefined` is treated as "no default value" while `null`
* is treated as "the default value is `null`".
*
* *Shorthand*: If you only need to configure the default value of the
* parameter, you may use a shorthand syntax. In the **`params`**
* map, instead mapping the param name to a full parameter configuration
* object, simply set map it to the default parameter value, e.g.:
*
* <pre>// define a parameter's default value
* params: {
* param1: { value: "defaultValue" }
* }
* // shorthand default values
* params: {
* param1: "defaultValue",
* param2: "param2Default"
* }</pre>
*
* - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
* treated as an array of values. If you specified a Type, the value will be
* treated as an array of the specified Type. Note: query parameter values
* default to a special `"auto"` mode.
*
* For query parameters in `"auto"` mode, if multiple values for a single parameter
* are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
* are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`). However, if
* only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
* value (e.g.: `{ foo: '1' }`).
*
* <pre>params: {
* param1: { array: true }
* }</pre>
*
* - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
* the current parameter value is the same as the default value. If `squash` is not set, it uses the
* configured default squash policy.
* (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
*
* There are three squash settings:
*
* - false: The parameter's default value is not squashed. It is encoded and included in the URL
* - true: The parameter's default value is omitted from the URL. If the parameter is preceeded and followed
* by slashes in the state's `url` declaration, then one of those slashes are omitted.
* This can allow for cleaner looking URLs.
* - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of your choice.
*
* <pre>params: {
* param1: {
* value: "defaultId",
* squash: true
* } }
* // squash "defaultValue" to "~"
* params: {
* param1: {
* value: "defaultValue",
* squash: "~"
* } }
* </pre>
*
*
* @example
* <pre>
* // Some state name examples
*
* // stateName can be a single top-level name (must be unique).
* $stateProvider.state("home", {});
*
* // Or it can be a nested state name. This state is a child of the
* // above "home" state.
* $stateProvider.state("home.newest", {});
*
* // Nest states as deeply as needed.
* $stateProvider.state("home.newest.abc.xyz.inception", {});
*
* // state() returns $stateProvider, so you can chain state declarations.
* $stateProvider
* .state("home", {})
* .state("about", {})
* .state("contacts", {});
* </pre>

* - `$state.go('^')` - will go to a parent state
* - `$state.go('^.sibling')` - will go to a sibling state
* - `$state.go('.child.grandchild')` - will go to grandchild state
*
* @param {object=} params A map of the parameters that will be sent to the state,
* will populate $stateParams. Any parameters that are not specified will be inherited from currently
* defined parameters. This allows, for example, going to a sibling state that shares parameters
* specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
* transitioning to a sibling will get you the parameters for all parents, transitioning to a child
* will get you all current parameters, etc.
* @param {object=} options Options object. The options are:
*
* - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
* will not. If string, must be `"replace"`, which will update url and also replace last history record.
* - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
* - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'),
* defines which state to be relative from.
* - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
* - **`reload`** (v0.2.5) - {boolean=false}, If `true` will force transition even if the state or params
* have not changed, aka a reload of the same state. It differs from reloadOnSearch because you'd
* use this when you want to force a reload when *everything* is the same, including search params.
*
* @returns {promise} A promise representing the state of the new transition.
*
* Possible success values:
*
* - $state.current
*
* <br/>Possible rejection values:

* - 'transition superseded' - when a newer transition has been started after this one
* - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener

* - *resolve error* - when an error has occurred with a `resolve`

* @requires $document
*
* @restrict ECA
*
* @description
* The ui-view directive tells $state where to place your templates.
*
* @param {string=} name A view name. The name should be unique amongst the other views in the
* same state. You can have views of the same name that live in different states.
*
* @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
* when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
* service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
* scroll ui-view elements into view when they are populated during a state activation.
*
* *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
* functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
*
* @param {string=} onload Expression to evaluate whenever the view updates.
*
* @example
* A view can be unnamed or named.
* <pre>
* <!-- Unnamed -->
* <div ui-view></div>
*
* <!-- Named -->
* <div ui-view="viewName"></div>
* </pre>
*
* You can only have one unnamed view within any template (or root html). If you are only using a
* single view and it is unnamed then you can populate it like so:
* <pre>
* <div ui-view></div>
* $stateProvider.state("home", {
* template: "<h1>HELLO!</h1>"
* })
* </pre>
*
* The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#views `views`}
* config property, by name, in this case an empty name:
* <pre>
* $stateProvider.state("home", {
* views: {
* "": {
* template: "<h1>HELLO!</h1>"
* }
* }
* })
* </pre>
*
* But typically you'll only use the views property if you name your view or have more than one view
* in the same template. There's not really a compelling reason to name a view if its the only one,
* but you could if you wanted, like so:
* <pre>
* <div ui-view="main"></div>
* </pre>
* <pre>
* $stateProvider.state("home", {
* views: {
* "main": {
* template: "<h1>HELLO!</h1>"
* }
* }
* })
* </pre>
*
* Really though, you'll use views to set up multiple views:
* <pre>
* <div ui-view></div>
* <div ui-view="chart"></div>
* <div ui-view="data"></div>
* </pre>
*
* <pre>
* $stateProvider.state("home", {
* views: {
* "": {
* template: "<h1>HELLO!</h1>"
* },
* "chart": {
* template: "<chart_thing/>"
* },
* "data": {
* template: "<data_thing/>"
* }
* }
* })
* </pre>
*
* Examples for `autoscroll`:
*
* <pre>
* <!-- If autoscroll present with no expression,
* then scroll ui-view into view -->
* <ui-view autoscroll/>
*
* <!-- If autoscroll present with valid expression,
* then scroll ui-view into view if expression evaluates to true -->
* <ui-view autoscroll='true'/>
* <ui-view autoscroll='false'/>
* <ui-view autoscroll='scopeVariable'/>
* </pre>

/**
* @ngdoc directive
* @name ui.router.state.directive:ui-sref
*
* @requires ui.router.state.$state
* @requires $timeout
*
* @restrict A
*
* @description
* A directive that binds a link (`<a>` tag) to a state. If the state has an associated
* URL, the directive will automatically generate & update the `href` attribute via
* the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
* the link will trigger a state transition with optional parameters.
*
* Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
* handled natively by the browser.
*
* You can also use relative state paths within ui-sref, just like the relative
* paths passed to `$state.go()`. You just need to be aware that the path is relative
* to the state that the link lives in, in other words the state that loaded the
* template containing the link.
*
* You can specify options to pass to {@link ui.router.state.$state#go $state.go()}
* using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
* and `reload`.
*
* @example
* Here's an example of how you'd use ui-sref and how it would compile. If you have the
* following template:
* <pre>
* <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
*
* <ul>
* <li ng-repeat="contact in contacts">
* <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
* </li>
* </ul>
* </pre>
*
* Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
* <pre>
* <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
*
* <ul>
* <li ng-repeat="contact in contacts">
* <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
* </li>
* <li ng-repeat="contact in contacts">
* <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>
* </li>
* <li ng-repeat="contact in contacts">
* <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>
* </li>
* </ul>
*
* <a ui-sref="home" ui-sref-opts="{reload: true}">Home</a>
* </pre>
*
* @param {string} ui-sref 'stateName' can be any valid absolute or relative state
* @param {Object} ui-sref-opts options to pass to {@link ui.router.state.$state#go $state.go()}

* @ngdoc directive
* @name ui.router.state.directive:ui-sref-active
*
* @requires ui.router.state.$state
* @requires ui.router.state.$stateParams
* @requires $interpolate
*
* @restrict A
*
* @description
* A directive working alongside ui-sref to add classes to an element when the
* related ui-sref directive's state is active, and removing them when it is inactive.
* The primary use-case is to simplify the special appearance of navigation menus
* relying on `ui-sref`, by having the "active" state's menu button appear different,
* distinguishing it from the inactive menu items.
*
* ui-sref-active can live on the same element as ui-sref or on a parent element. The first
* ui-sref-active found at the same level or above the ui-sref will be used.
*
* Will activate when the ui-sref's target state or any child state is active. If you
* need to activate only when the ui-sref target state is active and *not* any of
* it's children, then you will use
* {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
*
* @example
* Given the following template:
* <pre>
* <ul>
* <li ui-sref-active="active" class="item">
* <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
* </li>
* </ul>
* </pre>
*
*
* When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
* the resulting HTML will appear as (note the 'active' class):
* <pre>
* <ul>
* <li ui-sref-active="active" class="item active">
* <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
* </li>
* </ul>
* </pre>
*
* The class name is interpolated **once** during the directives link time (any further changes to the
* interpolated value are ignored).
*
* Multiple classes may be specified in a space-separated format:
* <pre>
* <ul>
* <li ui-sref-active='class1 class2 class3'>
* <a ui-sref="app.user">link</a>
* </li>
* </ul>
* </pre>
