         * 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:

         * 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:
         *
         *   - `{object}` - state - The state config object.

    /**
     * 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.

     * **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.
     *
     * ```html
     * <a ui-state="" ui-state-params="{ 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.
     * ```

    /**
     * `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 "common" being an abstract state:
     * ```html
     * <div ui-sref-active="{'active': 'common.**'}">
     *   <a ui-sref-active="active" ui-sref="common.roles">Roles</a>
     * </div>
     * ```
     *
     * Arrays are also supported as values in the `ngClass`-like interface.
     * This allows multiple states to add `active` class.
     *
     * #### Example:
     * Given the following template, with "common.roles" being the current state, the class will be added too:
     * ```html
     * <div ui-sref-active="{'active': ['owner.**', 'common.**']}">
     *   <a ui-sref-active="active" ui-sref="common.roles">Roles</a>
     * </div>
     * ```
     *
     * When the current state is "common.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(); }
     *   }
     * });
     * ```
