 * Returns a new function for [Partial Application](https://en.wikipedia.org/wiki/Partial_application) of the original function.
 *
 * Given a function with N parameters, returns a new function that supports partial application.
 * The new function accepts anywhere from 1 to N parameters.  When that function is called with M parameters,
 * where M is less than N, it returns a new function that accepts the remaining parameters.  It continues to
 * accept more parameters until all N parameters have been supplied.
 *
 *
 * This contrived example uses a partially applied function as an predicate, which returns true
 * if an object is found in both arrays.
 * @example
 * ```
 * // returns true if an object is in both of the two arrays
 * function inBoth(array1, array2, object) {
 *   return array1.indexOf(object) !== -1 &&
 *          array2.indexOf(object) !== 1;
 * }
 * let obj1, obj2, obj3, obj4, obj5, obj6, obj7
 * let foos = [obj1, obj3]
 * let bars = [obj3, obj4, obj5]
 *
 * // A curried "copy" of inBoth
 * let curriedInBoth = curry(inBoth);
 * // Partially apply both the array1 and array2
 * let inFoosAndBars = curriedInBoth(foos, bars);
 *
 * // Supply the final argument; since all arguments are
 * // supplied, the original inBoth function is then called.
 * let obj1InBoth = inFoosAndBars(obj1); // false
 *
 * // Use the inFoosAndBars as a predicate.
 * // Filter, on each iteration, supplies the final argument
 * let allObjs = [ obj1, obj2, obj3, obj4, obj5, obj6, obj7 ];
 * let foundInBoth = allObjs.filter(inFoosAndBars); // [ obj3 ]

/**
 * Matches state names using glob-like pattern strings.
 *
 * Globs can be used in specific APIs including:
 *
 * - [[StateService.is]]
 * - [[StateService.includes]]
 * - The first argument to Hook Registration functions like [[TransitionService.onStart]]
 *    - [[HookMatchCriteria]] and [[HookMatchCriterion]]
 *
 * A `Glob` string is a pattern which matches state names.
 * Nested state names are split into segments (separated by a dot) when processing.
 * The state named `foo.bar.baz` is split into three segments ['foo', 'bar', 'baz']
 *
 * Globs work according to the following rules:
 *
 * ### Exact match:
 *
 * The glob `'A.B'` matches the state named exactly `'A.B'`.
 *
 * | Glob        |Matches states named|Does not match state named|
 * |:------------|:--------------------|:---------------------|
 * | `'A'`       | `'A'`               | `'B'` , `'A.C'`      |
 * | `'A.B'`     | `'A.B'`             | `'A'` , `'A.B.C'`    |
 * | `'foo'`     | `'foo'`             | `'FOO'` , `'foo.bar'`|
 *
 * ### Single star (`*`)
 *
 * A single star (`*`) is a wildcard that matches exactly one segment.
 *
 * | Glob        |Matches states named  |Does not match state named |
 * |:------------|:---------------------|:--------------------------|
 * | `'*'`       | `'A'` , `'Z'`        | `'A.B'` , `'Z.Y.X'`       |
 * | `'A.*'`     | `'A.B'` , `'A.C'`    | `'A'` , `'A.B.C'`         |
 * | `'A.*.*'`   | `'A.B.C'` , `'A.X.Y'`| `'A'`, `'A.B'` , `'Z.Y.X'`|
 *
 * ### Double star (`**`)
 *
 * A double star (`'**'`) is a wildcard that matches *zero or more segments*
 *
 * | Glob        |Matches states named                           |Does not match state named         |
 * |:------------|:----------------------------------------------|:----------------------------------|
 * | `'**'`      | `'A'` , `'A.B'`, `'Z.Y.X'`                    | (matches all states)              |
 * | `'A.**'`    | `'A'` , `'A.B'` , `'A.C.X'`                   | `'Z.Y.X'`                         |
 * | `'**.X'`    | `'X'` , `'A.X'` , `'Z.Y.X'`                   | `'A'` , `'A.login.Z'`             |
 * | `'A.**.X'`  | `'A.X'` , `'A.B.X'` , `'A.B.C.X'`             | `'A'` , `'A.B.C'`                 |

     *
     * When a transition is created, the nodes in the "To Path" are injected from a ResolveContext.
     * A ResolveContext closes over a path of [[PathNode]]s and processes the resolvables.
     * The "To State" can inject values from its own resolvables, as well as those from all its ancestor state's (node's).
     * This method is used to create a narrower context when injecting ancestor nodes.
     *
     * @example
     * `let ABCD = new ResolveContext([A, B, C, D]);`
     *
     * Given a path `[A, B, C, D]`, where `A`, `B`, `C` and `D` are nodes for states `a`, `b`, `c`, `d`:
     * When injecting `D`, `D` should have access to all resolvables from `A`, `B`, `C`, `D`.
     * However, `B` should only be able to access resolvables from `A`, `B`.
     *
     * When resolving for the `B` node, first take the full "To Path" Context `[A,B,C,D]` and limit to the subpath `[A,B]`.
     * `let AB = ABCD.subcontext(a)`

     * Returns a Dependency Injector for the Transition's target state (to state).
     * The injector provides resolve values which the target state has access to.
     *
     * The `UIInjector` can also provide values from the native root/global injector (ng1/ng2).
     *
     * #### Example:
     * ```js
     * .onEnter({ entering: 'myState' }, trans => {
     *   var myResolveValue = trans.injector().get('myResolve');
     *   // Inject a global service from the global/native injector (if it exists)
     *   var MyService = trans.injector().get('MyService');
     * })
     * ```
     *
     * In some cases (such as `onBefore`), you may need access to some resolve data but it has not yet been fetched.
     * You can use [[UIInjector.getAsync]] to get a promise for the data.
     * #### Example:
     * ```js
     * .onBefore({}, trans => {
     *   return trans.injector().getAsync('myResolve').then(myResolveValue =>
     *     return myResolveValue !== 'ABORT';
     *   });
     * });
     * ```
     *
     * If a `state` is provided, the injector that is returned will be limited to resolve values that the provided state has access to.
     * This can be useful if both a parent state `foo` and a child state `foo.bar` have both defined a resolve such as `data`.
     * #### Example:
     * ```js
     * .onEnter({ to: 'foo.bar' }, trans => {
     *   // returns result of `foo` state's `data` resolve
     *   // even though `foo.bar` also has a `data` resolve
     *   var fooData = trans.injector('foo').get('data');
     * });
     * ```
     *
     * If you need resolve data from the exiting states, pass `'from'` as `pathName`.
     * The resolve data from the `from` path will be returned.
     * #### Example:
     * ```js
     * .onExit({ exiting: 'foo.bar' }, trans => {
     *   // Gets the resolve value of `data` from the exiting state.
     *   var fooData = trans.injector(null, 'foo.bar').get('data');
     * });
     * ```
     *
     *
     * @param state Limits the resolves provided to only the resolves the provided state has access to.
     * @param pathName Default: `'to'`: Chooses the path for which to create the injector. Use this to access resolves for `exiting` states.

/**
 * Matches URLs against patterns.
 *
 * 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 (query)
 * 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 [[UrlMatcher.exec]].
 *
 * - *Path parameters* are defined using curly brace placeholders (`/somepath/{param}`)
 * or colon placeholders (`/somePath/:param`).
 *
 * - *A parameter RegExp* may be defined for a param after a colon
 * (`/somePath/{param:[a-zA-Z0-9]+}`) in a curly brace placeholder.
 * The regexp must match for the url to be matched.
 * Should the regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
 *
 * Note: a RegExp parameter will encode its value using either [[ParamTypes.path]] or [[ParamTypes.query]].
 *
 * - *Custom parameter types* may also be specified after a colon (`/somePath/{param:int}`) in curly brace parameters.
 *   See [[UrlMatcherFactory.type]] for more information.
 *
 * - *Catch-all parameters* are defined using an asterisk placeholder (`/somepath/*catchallparam`).
 *   A catch-all * parameter value will contain the remainder of the URL.
 *
 * ---
 *
 * 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).
 * 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` ParamType matches `2014-11-12`) and provides a Date object in $stateParams.start

     * Given a ui-view and a ViewConfig, determines if they "match".
     *
     * A ui-view has a fully qualified name (fqn) and a context object.  The fqn is built from its overall location in
     * the DOM, describing its nesting relationship to any parent ui-view tags it is nested inside of.
     *
     * A ViewConfig has a target ui-view name and a context anchor.  The ui-view name can be a simple name, or
     * can be a segmented ui-view path, describing a portion of a ui-view fqn.
     *
     * In order for a ui-view to match ViewConfig, ui-view's $type must match the ViewConfig's $type
     *
     * If the ViewConfig's target ui-view name is a simple name (no dots), then a ui-view matches if:
     * - the ui-view's name matches the ViewConfig's target name
     * - the ui-view's context matches the ViewConfig's anchor
     *
     * If the ViewConfig's target ui-view name is a segmented name (with dots), then a ui-view matches if:
     * - There exists a parent ui-view where:
     *    - the parent ui-view's name matches the first segment (index 0) of the ViewConfig's target name
     *    - the parent ui-view's context matches the ViewConfig's anchor
     * - And the remaining segments (index 1..n) of the ViewConfig's target name match the tail of the ui-view's fqn
     *
     * Example:
     *
     * DOM:
     * <ui-view>                        <!-- created in the root context (name: "") -->
     *   <ui-view name="foo">                <!-- created in the context named: "A"      -->
     *     <ui-view>                    <!-- created in the context named: "A.B"    -->
     *       <ui-view name="bar">            <!-- created in the context named: "A.B.C"  -->
     *       </ui-view>
     *     </ui-view>
     *   </ui-view>
     * </ui-view>
     *

     *  { fqn: "$default",                  creationContext: { name: "" } },
     *  { fqn: "$default.foo",              creationContext: { name: "A" } },
     *  { fqn: "$default.foo.$default",     creationContext: { name: "A.B" } }
     *  { fqn: "$default.foo.$default.bar", creationContext: { name: "A.B.C" } }
     * ]
     *
     * These four view configs all match the ui-view with the fqn: "$default.foo.$default.bar":
     *
     * - ViewConfig1: { uiViewName: "bar",                       uiViewContextAnchor: "A.B.C" }
     * - ViewConfig2: { uiViewName: "$default.bar",              uiViewContextAnchor: "A.B" }
     * - ViewConfig3: { uiViewName: "foo.$default.bar",          uiViewContextAnchor: "A" }
     * - ViewConfig4: { uiViewName: "$default.foo.$default.bar", uiViewContextAnchor: "" }
     *
     * Using ViewConfig3 as an example, it matches the ui-view with fqn "$default.foo.$default.bar" because:
     * - The ViewConfig's segmented target name is: [ "foo", "$default", "bar" ]
     * - There exists a parent ui-view (which has fqn: "$default.foo") where:
     *    - the parent ui-view's name "foo" matches the first segment "foo" of the ViewConfig's target name
     *    - the parent ui-view's context "A" matches the ViewConfig's anchor context "A"
     * - And the remaining segments [ "$default", "bar" ].join("."_ of the ViewConfig's target name match

     * Adds a plugin to UI-Router
     *
     * This method adds a UI-Router Plugin.
     * A plugin can enhance or change UI-Router behavior using any public API.
     *
     * #### Example:
     * ```js
     * import { MyCoolPlugin } from "ui-router-cool-plugin";
     *
     * var plugin = router.addPlugin(MyCoolPlugin);
     * ```
     *
     * ### Plugin authoring
     *
     * A plugin is simply a class (or constructor function) which accepts a [[UIRouter]] instance and (optionally) an options object.
     *
     * The plugin can implement its functionality using any of the public APIs of [[UIRouter]].
     * For example, it may configure router options or add a Transition Hook.
     *
     * The plugin can then be published as a separate module.
     *
     * #### Example:
     * ```js
     * export class MyAuthPlugin implements UIRouterPlugin {
     *   constructor(router: UIRouter, options: any) {
     *     this.name = "MyAuthPlugin";
     *     let $transitions = router.transitionService;
     *     let $state = router.stateService;
     *
     *     let authCriteria = {
     *       to: (state) => state.data && state.data.requiresAuth
     *     };
     *
     *     function authHook(transition: Transition) {
     *       let authService = transition.injector().get('AuthService');
     *       if (!authService.isAuthenticated()) {
     *         return $state.target('login');
     *       }
     *     }
     *
     *     $transitions.onStart(authCriteria, authHook);
     *   }
     * }
     * ```
     *
     * @param plugin one of:
     *        - a plugin class which implements [[UIRouterPlugin]]
     *        - a constructor function for a [[UIRouterPlugin]] which accepts a [[UIRouter]] instance
     *        - a factory function which accepts a [[UIRouter]] instance and returns a [[UIRouterPlugin]] instance

     * `$state.go` calls `$state.transitionTo` internally but automatically sets options to
     * `{ location: true, inherit: true, relative: router.globals.$current, notify: true }`.
     * This allows you to use either an absolute or relative `to` argument (because of `relative: router.globals.$current`).

     * - `$state.go('^')` - will go to the parent state
     * - `$state.go('^.sibling')` - if current state is `home.child`, will go to the `home.sibling` state
     * - `$state.go('.child.grandchild')` - if current state is home, will go to the `home.child.grandchild` state
     *
     * @param 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 current parameter values (because of `inherit: true`).
     *    This allows, for example, going to a sibling state that shares parameters defined by a parent state.

 * A basic angular1-like injector api

 * This object provides a naive implementation of a globally scoped dependency injection system.

 *
 * ### Function parameter names
 *
 * A function's `.toString()` is called, and the parameter names are parsed.
 * This only works when the parameter names aren't "mangled" by a minifier such as UglifyJS.
 *
 * ```js
 * function injectedFunction(FooService, BarService) {
 *   // FooService and BarService are injected
 * }
 * ```
 *
 * ### Function annotation
 *
 * A function may be annotated with an array of dependency names as the `$inject` property.
 *
 * ```js
 * injectedFunction.$inject = [ 'FooService', 'BarService' ];
 * function injectedFunction(fs, bs) {
 *   // FooService and BarService are injected as fs and bs parameters
 * }
 * ```
 *
 * ### Array notation
 *
 * An array provides the names of the dependencies to inject (as strings).
 * The function is the last element of the array.
 *
 * ```js
 * [ 'FooService', 'BarService', function (fs, bs) {
 *   // FooService and BarService are injected as fs and bs parameters
 * }]

 * The Angular 1 `StateProvider`
 *
 * The `$stateProvider` works similar to Angular's v1 router, but it focuses purely
 * on state.
 *
 * A state corresponds to a "place" in the application in terms of the overall UI and
 * navigation. A state describes (via the controller / template / view properties) what
 * the UI looks like and does at that place.
 *
 * States often have things in common, and the primary way of factoring out these
 * commonalities in this model is via the state hierarchy, i.e. parent/child states aka
 * nested states.
 *
 * The `$stateProvider` provides interfaces to declare these states for your app.
 */
var StateProvider = /** @class */ (function () {
    function StateProvider(stateRegistry, stateService) {
        this.stateRegistry = stateRegistry;

    /**
     * Decorates states when they are registered
     *
     * Allows you to extend (carefully) or override (at your own peril) the
     * `stateBuilder` object used internally by [[StateRegistry]].
     * 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:
     * Override the internal 'views' builder with a function that takes the state
     * definition, and a reference to the internal function being overridden:
     * ```js
     * $stateProvider.decorator('views', function (state, parent) {
     *   let result = {},
     *       views = parent(state);
     *
     *   angular.forEach(views, function (config, name) {
     *     let 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' }
     *   }
     * });
     * ```
     *
     *
     * ```js
     * // Auto-populates list and item views with /partials/home/contact/list.html,
     * // and /partials/home/contact/item.html, respectively.
     * $state.go('home');
     * ```
     *
     * @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:

/**
 * # Angular 1 injectable services
 *
 * This is a list of the objects which can be injected using angular's injector.
 *
 * There are three different kind of injectable objects:
 *
 * ## **Provider** objects
 * #### injectable into a `.config()` block during configtime
 *
 * - [[$uiRouterProvider]]: The UI-Router instance
 * - [[$stateProvider]]: State registration
 * - [[$transitionsProvider]]: Transition hooks
 * - [[$urlServiceProvider]]: All URL related public APIs
 *
 * - [[$uiViewScrollProvider]]: Disable ui-router view scrolling
 * - [[$urlRouterProvider]]: (deprecated) Url matching rules
 * - [[$urlMatcherFactoryProvider]]: (deprecated) Url parsing config
 *
 * ## **Service** objects
 * #### injectable globally during runtime
 *
 * - [[$uiRouter]]: The UI-Router instance
 * - [[$trace]]: Enable transition trace/debug
 * - [[$transitions]]: Transition hooks
 * - [[$state]]: Imperative state related APIs
 * - [[$stateRegistry]]: State registration
 * - [[$urlService]]: All URL related public APIs
 * - [[$uiRouterGlobals]]: Global variables
 * - [[$uiViewScroll]]: Scroll an element into view
 *
 * - [[$stateParams]]: (deprecated) Global state param values
 * - [[$urlRouter]]: (deprecated) URL synchronization
 * - [[$urlMatcherFactory]]: (deprecated) URL parsing config
 *
 * ## **Per-Transition** objects
 *
 * - These kind of objects are injectable into:
 *   - Resolves ([[Ng1StateDeclaration.resolve]]),
 *   - Transition Hooks ([[TransitionService.onStart]], etc),
 *   - Routed Controllers ([[Ng1ViewDeclaration.controller]])
 *
 * #### Different instances are injected based on the [[Transition]]
 *
 * - [[$transition$]]: The current Transition object
 * - [[$stateParams]]: State param values for pending Transition (deprecated)
 * - Any resolve data defined using [[Ng1StateDeclaration.resolve]]

/**
 * The current (or pending) State Parameters
 *
 * An injectable global **Service Object** which holds the state parameters for the latest **SUCCESSFUL** transition.
 *
 * The values are not updated until *after* a `Transition` successfully completes.
 *
 * **Also:** an injectable **Per-Transition Object** object which holds the pending state parameters for the pending `Transition` currently running.
 *
 * ### Deprecation warning:
 *
 * The value injected for `$stateParams` is different depending on where it is injected.
 *
 * - When injected into an angular service, the object injected is the global **Service Object** with the parameter values for the latest successful `Transition`.
 * - When injected into transition hooks, resolves, or view controllers, the object is the **Per-Transition Object** with the parameter values for the running `Transition`.
 *
 * Because of these confusing details, this service is deprecated.
 *
 * ### Instead of using the global `$stateParams` service object,
 * inject [[$uiRouterGlobals]] and use [[UIRouterGlobals.params]]
 *
 * ```js
 * MyService.$inject = ['$uiRouterGlobals'];
 * function MyService($uiRouterGlobals) {
 *   return {
 *     paramValues: function () {
 *       return $uiRouterGlobals.params;
 *     }
 *   }
 * }
 * ```
 *
 * ### Instead of using the per-transition `$stateParams` object,
 * inject the current `Transition` (as [[$transition$]]) and use [[Transition.params]]
 *
 * ```js
 * MyController.$inject = ['$transition$'];
 * function MyController($transition$) {
 *   var username = $transition$.params().username;
 *   // .. do something with username
 * }
 * ```
 *
 * ---
 *
 * This object can be injected into other services.
 *
 * #### Deprecated Example:
 * ```js
 * SomeService.$inject = ['$http', '$stateParams'];
 * function SomeService($http, $stateParams) {
 *   return {
 *     getUser: function() {
 *       return $http.get('/api/users/' + $stateParams.username);
 *     }
 *   }
 * };
 * angular.service('SomeService', SomeService);

/**
 * `ui-sref`: A directive for linking to a state
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * ### Linked State
 * The attribute value of the `ui-sref` is the name of the state to link to.
 *
 * #### Example:
 * This will activate the `home` state when the link is clicked.
 * ```html
 * <a ui-sref="home">Home</a>
 * ```
 *
 * ### Relative Links
 * You can also use relative state paths within `ui-sref`, just like a relative path passed to `$state.go()` ([[StateService.go]]).
 * You just need to be aware that the path is relative to the state that *created* the link.
 * This allows a state to create a relative `ui-sref` which always targets the same destination.
 *
 * #### Example:
 * Both these links are relative to the parent state, even when a child state is currently active.
 * ```html
 * <a ui-sref=".child1">child 1 state</a>
 * <a ui-sref=".child2">child 2 state</a>
 * ```
 *
 * This link activates the parent state.
 * ```html
 * <a ui-sref="^">Return</a>
 * ```
 *
 * ### hrefs
 * If the linked state has a URL, the directive will automatically generate and
 * update the `href` attribute (using the [[StateService.href]]  method).
 *
 * #### Example:
 * Assuming the `users` state has a url of `/users/`
 * ```html
 * <a ui-sref="users" href="/users/">Users</a>
 * ```
 *
 * ### Parameter Values
 * In addition to the state name, a `ui-sref` can include parameter values which are applied when activating the state.
 * Param values can be provided in the `ui-sref` value after the state name, enclosed by parentheses.
 * The content inside the parentheses is an expression, evaluated to the parameter values.
 *
 * #### Example:
 * This example renders a list of links to users.
 * The state's `userId` parameter value comes from each user's `user.id` property.
 * ```html
 * <li ng-repeat="user in users">
 *   <a ui-sref="users.detail({ userId: user.id })">{{ user.displayName }}</a>
 * </li>
 * ```
 *
 * Note:
 * The parameter values expression is `$watch`ed for updates.
 *
 * ### Transition Options
 * You can specify [[TransitionOptions]] to pass to [[StateService.go]] by using the `ui-sref-opts` attribute.
 * Options are restricted to `location`, `inherit`, and `reload`.
 *
 * #### Example:
 * ```html
 * <a ui-sref="home" ui-sref-opts="{ reload: true }">Home</a>
 * ```
 *
 * ### Other DOM Events
 *
 * You can also customize which DOM events to respond to (instead of `click`) by
 * providing an `events` array in the `ui-sref-opts` attribute.
 *
 * #### Example:
 * ```html
 * <input type="text" ui-sref="contacts" ui-sref-opts="{ events: ['change', 'blur'] }">
 * ```
 *
 * ### Highlighting the active link
 * This directive can be used in conjunction with [[uiSrefActive]] to highlight the active link.
 *
 * ### Examples
 * If you have the following template:
 *
 * ```html
 * <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>
 * ```
 *
 * Then (assuming the current state is `contacts`) the rendered html including hrefs would be:
 *
 * ```html
 * <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 href="#/home" ui-sref="home" ui-sref-opts="{reload: true}">Home</a>
 * ```
 *
 * ### Notes
 *
 * - You can use `ui-sref` to change **only the parameter values** by omitting the state name and parentheses.
 * #### Example:
 * Sets the `lang` parameter to `en` and remains on the same state.
 *
 * ```html
 * <a ui-sref="{ lang: 'en' }">English</a>
 * ```
 *
 * - A middle-click, right-click, or ctrl-click is handled (natively) by the browser to open the href in a new window, for example.
 *
 * - Unlike the parameter values expression, the state name is not `$watch`ed (for performance reasons).
 * If you need to dynamically update the state being linked to, use the fully dynamic [[uiState]] directive.

/**
 * `ui-state`: A fully dynamic directive for linking to a state
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * **This directive is very similar to [[uiSref]], but it `$observe`s and `$watch`es/evaluates all its inputs.**
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * ### Linked State
 * The attribute value of `ui-state` is an expression which is `$watch`ed and evaluated as the state to link to.
 * **This is in contrast with `ui-sref`, which takes a state name as a string literal.**
 *
 * #### Example:
 * Create a list of links.
 * ```html
 * <li ng-repeat="link in navlinks">
 *   <a ui-state="link.state">{{ link.displayName }}</a>
 * </li>
 * ```
 *
 * ### Relative Links
 * If the expression evaluates to a relative path, it is processed like [[uiSref]].
 * You just need to be aware that the path is relative to the state that *created* the link.
 * This allows a state to create relative `ui-state` which always targets the same destination.
 *
 * ### hrefs
 * If the linked state has a URL, the directive will automatically generate and
 * update the `href` attribute (using the [[StateService.href]]  method).
 *
 * ### Parameter Values
 * In addition to the state name expression, a `ui-state` can include parameter values which are applied when activating the state.
 * Param values should be provided using the `ui-state-params` attribute.
 * The `ui-state-params` attribute value is `$watch`ed and evaluated as an expression.
 *
 * #### Example:
 * This example renders a list of links with param values.
 * The state's `userId` parameter value comes from each user's `user.id` property.
 * ```html
 * <li ng-repeat="link in navlinks">
 *   <a ui-state="link.state" ui-state-params="link.params">{{ link.displayName }}</a>
 * </li>
 * ```
 *
 * ### Transition Options
 * You can specify [[TransitionOptions]] to pass to [[StateService.go]] by using the `ui-state-opts` attribute.
 * Options are restricted to `location`, `inherit`, and `reload`.
 * The value of the `ui-state-opts` is `$watch`ed and evaluated as an expression.
 *
 * #### Example:
 * ```html
 * <a ui-state="returnto.state" ui-state-opts="{ reload: true }">Home</a>
 * ```
 *
 * ### Other DOM Events
 *
 * You can also customize which DOM events to respond to (instead of `click`) by
 * providing an `events` array in the `ui-state-opts` attribute.
 *
 * #### Example:
 * ```html
 * <input type="text" ui-state="contacts" ui-state-opts="{ events: ['change', 'blur'] }">
 * ```
 *
 * ### Highlighting the active link
 * This directive can be used in conjunction with [[uiSrefActive]] to highlight the active link.
 *
 * ### Notes
 *
 * - You can use `ui-params` to change **only the parameter values** by omitting the state name and supplying only `ui-state-params`.
 *   However, it might be simpler to use [[uiSref]] parameter-only links.
 *
 * #### Example:
 * Sets the `lang` parameter to `en` and remains on the same state.

/**
 * `ui-sref-active` and `ui-sref-active-eq`: A directive that adds a CSS class when a `ui-sref` is active
 *
 * A directive working alongside [[uiSref]] and [[uiState]] to add classes to an element when the
 * related directive's state is active (and remove them when it is inactive).
 *
 * The primary use-case is to highlight the active link in navigation menus,
 * distinguishing it from the inactive menu items.
 *
 * ### Linking to a `ui-sref` or `ui-state`
 * `ui-sref-active` can live on the same element as `ui-sref`/`ui-state`, or it can be on a parent element.
 * If a `ui-sref-active` is a parent to more than one `ui-sref`/`ui-state`, it will apply the CSS class when **any of the links are active**.
 *
 * ### Matching
 *
 * The `ui-sref-active` directive applies the CSS class when the `ui-sref`/`ui-state`'s target state **or any child state is active**.
 * This is a "fuzzy match" which uses [[StateService.includes]].
 *
 * The `ui-sref-active-eq` directive applies the CSS class when the `ui-sref`/`ui-state`'s target state is directly active (not when child states are active).
 * This is an "exact match" which uses [[StateService.is]].
 *
 * ### Parameter values
 * If the `ui-sref`/`ui-state` includes parameter values, the current parameter values must match the link's values for the link to be highlighted.
 * This allows a list of links to the same state with different parameters to be rendered, and the correct one highlighted.
 *
 * #### Example:
 * ```html
 * <li ng-repeat="user in users" ui-sref-active="active">
 *   <a ui-sref="user.details({ userId: user.id })">{{ user.lastName }}</a>
 * </li>
 * ```
 *
 * ### Examples
 *
 * Given the following template:
 * #### Example:
 * ```html
 * <ul>
 *   <li ui-sref-active="active" class="item">
 *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
 *   </li>
 * </ul>
 * ```
 *
 * When the app state is `app.user` (or any child state),
 * and contains the state parameter "user" with value "bilbobaggins",
 * the resulting HTML will appear as (note the 'active' class):
 *
 * ```html
 * <ul>
 *   <li ui-sref-active="active" class="item active">
 *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
 *   </li>
 * </ul>
 * ```
 *
 * ### Glob mode
 *
 * It is possible to pass `ui-sref-active` an expression that evaluates to an object.
 * The objects keys represent active class names and values represent the respective state names/globs.
 * `ui-sref-active` will match if the current active state **includes** any of
 * the specified state names/globs, even the abstract ones.
 *
 * #### Example:
 * Given the following template, with "admin" being an abstract state:
 * ```html
 * <div ui-sref-active="{'active': 'admin.**'}">
 *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
 * </div>
 * ```
 *
 * When the current state is "admin.roles" the "active" class will be applied to both the <div> and <a> elements.
 * It is important to note that the state names/globs passed to `ui-sref-active` override any state provided by a linked `ui-sref`.
 *
 * ### Notes:
 *
 * - 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: `ui-sref-active='class1 class2 class3'`

/**
 * `ui-view`: A viewport directive which is filled in by a view from the active state.
 *
 * ### Attributes
 *
 * - `name`: (Optional) 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.
 *   The ui-view can be targeted in a View using the name ([[Ng1StateDeclaration.views]]).
 *
 * - `autoscroll`: an expression. When it evaluates to true, the `ui-view` will be scrolled into view when it is activated.
 *   Uses [[$uiViewScroll]] to do the scrolling.
 *
 * - `onload`: Expression to evaluate whenever the view updates.
 *
 * #### Example:
 * A view can be unnamed or named.
 * ```html
 * <!-- Unnamed -->
 * <div ui-view></div>
 *
 * <!-- Named -->
 * <div ui-view="viewName"></div>
 *
 * <!-- Named (different style) -->
 * <ui-view name="viewName"></ui-view>
 * ```
 *
 * 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:
 *
 * ```html
 * <div ui-view></div>
 * $stateProvider.state("home", {
 *   template: "<h1>HELLO!</h1>"
 * })
 * ```
 *
 * The above is a convenient shortcut equivalent to specifying your view explicitly with the
 * [[Ng1StateDeclaration.views]] config property, by name, in this case an empty name:
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }
 * })
 * ```
 *
 * 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:
 *
 * ```html
 * <div ui-view="main"></div>
 * ```
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "main": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }
 * })
 * ```
 *
 * Really though, you'll use views to set up multiple views:
 *
 * ```html
 * <div ui-view></div>
 * <div ui-view="chart"></div>
 * <div ui-view="data"></div>
 * ```
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     },
 *     "chart": {
 *       template: "<chart_thing/>"
 *     },
 *     "data": {
 *       template: "<data_thing/>"
 *     }
 *   }
 * })
 * ```
 *
 * #### Examples for `autoscroll`:
 * ```html
 * <!-- If autoscroll present with no expression,
 *      then scroll ui-view into view -->
 * <ui-view autoscroll/>
 *
 * <!-- If autoscroll present with valid expression,
 *      then scroll ui-view into view if expression evaluates to true -->
 * <ui-view autoscroll='true'/>
 * <ui-view autoscroll='false'/>
 * <ui-view autoscroll='scopeVariable'/>
 * ```
 *
 * Resolve data:
 *
 * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
 * can be customized using [[Ng1ViewDeclaration.resolveAs]]).  This can be then accessed from the template.
 *
 * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
 * controller is instantiated.  The `$onInit()` hook can be used to perform initialization code which
 * depends on `$resolve` data.
 *
 * #### Example:
 * ```js
 * $stateProvider.state('home', {
 *   template: '<my-component user="$resolve.user"></my-component>',
 *   resolve: {
 *     user: function(UserService) { return UserService.fetchUser(); }
 *   }
 * });
 * ```
