- * @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>
- *
- * It is also possible to pass ui-sref-active an expression that evaluates
- * to an object hash, whose keys represent active class names and whose
- * 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:
- * <pre>
- * <div ui-sref-active="{'active': 'admin.*'}">
- * <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
- * </div>
- * </pre>
- *
- * 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 shadow the state provided by ui-sref.
