This is commonly referred to as a\n * \"default substate\".\n *\n * @example\n * ```js\n * // ng2\n * transitionService.onBefore({ to: 'home' }, (trans: Transition) =>\n * trans.router.stateService.target(\"home.dashboard\"));\n * ```\n *\n * #### Data Driven Default Substate\n *\n * This example provides data-driven default substate functionality. It matches on a transition to any state\n * which has `defaultSubstate: \"some.sub.state\"` defined. See: [[Transition.to]] which returns the \"to state\"\n * definition.\n *\n * @example\n * ```js\n * // ng1\n * // state declaration\n * {\n * name: 'home',\n * template: '<div ui-view/>',\n * defaultSubstate: 'home.dashboard'\n * }\n *\n * var criteria = {\n * to: function(state) {\n * return state.defaultSubstate != null;\n * }\n * }\n *\n * $transitions.onBefore(criteria, function(trans: Transition) {\n * var substate = trans.to().defaultSubstate;\n * return trans.router.stateService.target(substate);\n * });\n * ```\n *\n *\n * #### Require authentication\n *\n * This example cancels a transition to a state which requires authentication, if the user is not currently authenticated.\n *\n * This example assumes a state tree where all states which require authentication are children of a parent `'requireauth'` state.\n * This example assumes `MyAuthService` synchronously returns a boolean from `isAuthenticated()`.\n *\n * #### Example:\n * ```js\n * // ng1\n * $transitions.onBefore( { to: 'requireauth.**' }, function(trans) {\n * var myAuthService = trans.injector().get('MyAuthService');\n * // If isAuthenticated returns false, the transition is cancelled.\n * return myAuthService.isAuthenticated();\n * });\n * ```\n *\n * @param matchCriteria defines which Transitions the Hook should be invoked for.\n * @param callback the hook function which will be invoked.\n * @returns a function which deregisters the hook.\n */\n onBefore(matchCriteria: HookMatchCriteria, callback: TransitionHookFn, options?: HookRegOptions): Function;\n\n /**\n * Registers a [[TransitionHookFn]], called when a transition starts.\n *\n * Registers a transition lifecycle hook, which is invoked as a transition starts running.\n * This hook can be useful to perform some asynchronous action before completing a transition.\n *\n * See [[TransitionHookFn]] for the signature of the function.\n *\n * The [[HookMatchCriteria]] is used to determine which Transitions the hook should be invoked for.\n * To match all Transitions, use an empty criteria object `{}`.\n *\n * ### Lifecycle\n *\n * `onStart` hooks are invoked asynchronously when the Transition starts running.\n * This happens after the `onBefore` phase is complete.\n * At this point, the Transition has not yet exited nor entered any states.\n * The registered `onStart` hooks are invoked in priority order.\n *\n * Note: A built-in `onStart` hook with high priority is used to fetch any eager resolve data.\n *\n * ### Return value\n *\n * The hook's return value can be used to pause, cancel, or redirect the current Transition.\n * See [[HookResult]] for more information.\n *\n * ### Example\n *\n * #### Login during transition\n *\n * This example intercepts any transition to a state which requires authentication, when the user is\n * not currently authenticated. It allows the user to authenticate asynchronously, then resumes the\n * transition. If the user did not authenticate successfully, it redirects to the \"guest\" state, which\n * does not require authentication.\n *\n * This example assumes:\n * - a state tree where all states which require authentication are children of a parent `'auth'` state.\n * - `MyAuthService.isAuthenticated()` synchronously returns a boolean.\n * - `MyAuthService.authenticate()` presents a login dialog, and returns a promise which is resolved\n * or rejected, whether or not the login attempt was successful.\n *\n * #### Example:\n * ```js\n * // ng1\n * $transitions.onStart( { to: 'auth.**' }, function(trans) {\n * var $state = trans.router.stateService;\n * var MyAuthService = trans.injector().get('MyAuthService');\n *\n * // If the user is not authenticated\n * if (!MyAuthService.isAuthenticated()) {\n *\n * // Then return a promise for a successful login.\n * // The transition will wait for this promise to settle\n *\n * return

This property\n * takes precedence over templateUrl.\n *\n * If `template` is a function, it will be called with the following parameters:\n *\n * - {array.<object>} - state parameters extracted from the current $location.path() by\n * applying the current state\n *\n * <a id='templateUrl'></a>\n *\n * - **`templateUrl`** - {string|function=} - path or function that returns a path to an html\n * template that should be used by uiView.\n *\n * If `templateUrl` is a function, it will be called with the following parameters:\n *\n * - {array.<object>} - state parameters extracted from the current $location.path() by\n * applying the current state\n *\n * <a id='templateProvider'></a>\n *\n * - **`templateProvider`** - {function=} - Provider function that returns HTML content\n * string.\n *\n * <a id='controller'></a>\n *\n * - **`controller`** - {string|function=} - Controller fn that should be associated with newly\n * related scope or the name of a registered controller if passed as a string.\n *\n * <a id='controllerProvider'></a>\n *\n * - **`controllerProvider`** - {function=} - Injectable provider function that returns\n * the actual controller or string.\n *\n * <a id='controllerAs'></a>\n *\n * - **`controllerAs`** – {string=} – A controller alias name. If present the controller will be\n * published to scope under the controllerAs name.\n *\n * <a id='resolve'></a>\n *\n * - **`resolve`** - {object.<string, function>=} - An optional map of dependencies which\n * should be injected into the controller. If any of these dependencies are promises,\n * the router will wait for them all to be resolved or one to be rejected before the\n * controller is instantiated. If all the promises are resolved successfully, the values\n * of the resolved promises are injected and $stateChangeSuccess event is fired. If any\n * of the promises are rejected the $stateChangeError event is fired. The map object is:\n *\n * - key - {string}: name of dependency to be injected into controller\n * - factory - {string|function}: If string then it is alias for service. Otherwise if function,\n * it is injected and return value it treated as dependency. If result is a promise, it is\n * resolved before its value is injected into controller.\n *\n * <a id='url'></a>\n *\n * - **`url`** - {string=} - A url with optional parameters. When a state is navigated or\n * transitioned to, the `$stateParams` service will be populated with any\n * parameters that were passed.\n *\n * <a id='params'></a>\n *\n * - **`params`** - {object=} - An array of parameter names or regular expressions. Only\n * use this within a state if you are not using url. Otherwise you can specify your\n * parameters within the url. When a state is navigated or transitioned to, the\n * $stateParams service will be populated with any parameters that were passed.\n *\n * <a id='views'></a>\n *\n * - **`views`** - {object=} - Use the views property to set up multiple views or to target views\n * manually/explicitly.\n *\n * <a id='abstract'></a>\n *\n * - **`abstract`** - {boolean=} - An abstract state will never be directly activated,\n * but can provide inherited properties to its common children states.\n *\n * <a id='onEnter'></a>\n *\n * - **`onEnter`** - {object=} - Callback function for when a state is entered. Good way\n * to trigger an action or dispatch an event, such as opening a dialog.\n * If minifying your scripts, make sure to use the `['injection1', 'injection2', function(injection1, injection2){}]` syntax.\n *\n * <a id='onExit'></a>\n *\n * - **`onExit`** - {object=} - Callback function for when a state is exited. Good way to\n * trigger an action or dispatch an event, such as opening a dialog.\n * If minifying your scripts, make sure to use the `['injection1', 'injection2', function(injection1, injection2){}]` syntax.\n *\n * <a id='reloadOnSearch'></a>\n *\n * - **`reloadOnSearch = true`** - {boolean=} - If `false`, will not retrigger the same state\n * just because a search/query parameter has changed (via $location.search() or $location.hash()).\n * Useful for when you'd like to modify $location.search() without triggering a reload.\n *\n * <a id='data'></a>\n *\n * - **`data`** - {object=} - Arbitrary data object, useful for custom configuration.\n *\n * #### Example:\n * Some state name examples\n * ```js\n * // stateName can be a single top-level name (must be unique).\n * $stateProvider.state(\"home\", {});\n *\n * // Or it can be a nested state name. This state is a child of the\n * // above \"home\" state.\n * $stateProvider.state(\"home.newest\", {});\n *\n * // Nest states as deeply as needed.\n * $stateProvider.state(\"home.newest.abc.xyz.inception\", {});\n *\n * // state() returns $stateProvider, so you can chain state declarations.\n * $stateProvider\n * .state(\"home\", {})\n * .state(\"about\", {})\n * .state(\"contacts\", {});\n * ```\n *\n * @param {string} name A unique state name, e.g. \"home\", \"about\", \"contacts\".\n * To create a parent/child state use a dot, e.g. \"about.sales\", \"home.newest\".\n * @param {object} definition State configuration object.\n */\n state(name: string, definition: Ng1StateDeclaration): StateProvider;\n state(definition: Ng1StateDeclaration): StateProvider;\n state(name: any, definition?: any) {\n if (isObject(name)) {\n definition = name;\n } else {\n definition.name = name;\n }\n this.stateRegistry.register(definition);\n return this;\n }\n\n /**\n * Registers an invalid state handler\n *\n * This is a passthrough to [[StateService.onInvalid]] for ng1.\n */\n\n onInvalid(callback: OnInvalidCallback): Function {\n return this.stateService.onInvalid(callback);\n }\n}\n",

(and optionally, parameters).\n * When clicked, this directive activates the linked state with the supplied parameter values.\n *\n * ### Linked State\n * The attribute value of the `ui-sref` is the name of the state to link to.\n *\n * #### Example:\n * This will activate the `home` state when the link is clicked.\n * ```html\n * <a ui-sref=\"home\">Home</a>\n * ```\n *\n * ### Relative Links\n * You can also use relative state paths within `ui-sref`, just like a relative path passed to `$state.go()` ([[StateService.go]]).\n * You just need to be aware that the path is relative to the state that *created* the link.\n * This allows a state to create a relative `ui-sref` which always targets the same destination.\n *\n * #### Example:\n * Both these links are relative to the parent state, even when a child state is currently active.\n * ```html\n * <a ui-sref=\".child1\">child 1 state</a>\n * <a ui-sref=\".child2\">child 2 state</a>\n * ```\n *\n * This link activates the parent state.\n * ```html\n * <a ui-sref=\"^\">Return</a>\n * ```\n *\n * ### hrefs\n * If the linked state has a URL, the directive will automatically generate and\n * update the `href` attribute (using the [[StateService.href]] method).\n *\n * #### Example:\n * Assuming the `users` state has a url of `/users/`\n * ```html\n * <a ui-sref=\"users\" href=\"/users/\">Users</a>\n * ```\n *\n * ### Parameter Values\n * In addition to the state name, a `ui-sref` can include parameter values which are applied when activating the state.\n * Param values can be provided in the `ui-sref` value after the state name, enclosed by parentheses.\n * The content inside the parentheses is an expression, evaluated to the parameter values.\n *\n * #### Example:\n * This example renders a list of links to users.\n * The state's `userId` parameter value comes from each user's `user.id` property.\n * ```html\n * <li ng-repeat=\"user in users\">\n * <a ui-sref=\"users.detail({ userId: user.id })\">{{ user.displayName }}</a>\n * </li>\n * ```\n *\n * Note:\n * The parameter values expression is `$watch`ed for updates.\n *\n * ### Transition Options\n * You can specify [[TransitionOptions]] to pass to [[StateService.go]] by using the `ui-sref-opts` attribute.\n * Options are restricted to `location`, `inherit`, and `reload`.\n *\n * #### Example:\n * ```html\n * <a ui-sref=\"home\" ui-sref-opts=\"{ reload: true }\">Home</a>\n * ```\n *\n * ### Other DOM Events\n *\n * You can also customize which DOM events to respond to (instead of `click`) by\n * providing an `events` array in the `ui-sref-opts` attribute.\n *\n * #### Example:\n * ```html\n * <input type=\"text\" ui-sref=\"contacts\" ui-sref-opts=\"{ events: ['change', 'blur'] }\">\n * ```\n *\n * ### Highlighting the active link\n * This directive can be used in conjunction with [[uiSrefActive]] to highlight the active link.\n *\n * ### Examples\n * If you have the following template:\n *\n * ```html\n * <a ui-sref=\"home\">Home</a>\n * <a ui-sref=\"about\">About</a>\n * <a ui-sref=\"{page: 2}\">Next page</a>\n *\n * <ul>\n * <li ng-repeat=\"contact in contacts\">\n * <a ui-sref=\"contacts.detail({ id: contact.id })\">{{ contact.name }}</a>\n * </li>\n * </ul>\n * ```\n *\n * Then (assuming the current state is `contacts`) the rendered html including hrefs would be:\n *\n * ```html\n * <a href=\"#/home\" ui-sref=\"home\">Home</a>\n * <a href=\"#/about\" ui-sref=\"about\">About</a>\n * <a href=\"#/contacts?page=2\" ui-sref=\"{page: 2}\">Next page</a>\n *\n * <ul>\n * <li ng-repeat=\"contact in contacts\">\n * <a href=\"#/contacts/1\" ui-sref=\"contacts.detail({ id: contact.id })\">Joe</a>\n * </li>\n * <li ng-repeat=\"contact in contacts\">\n * <a href=\"#/contacts/2\" ui-sref=\"contacts.detail({ id: contact.id })\">Alice</a>\n * </li>\n * <li ng-repeat=\"contact in contacts\">\n * <a href=\"#/contacts/3\" ui-sref=\"contacts.detail({ id: contact.id })\">Bob</a>\n * </li>\n * </ul>\n *\n * <a href=\"#/home\" ui-sref=\"home\" ui-sref-opts=\"{reload: true}\">Home</a>\n * ```\n *\n * ### Notes\n *\n * - You can use `ui-sref` to change **only the parameter values** by omitting the state name and parentheses.\n * #### Example:\n * Sets the `lang` parameter to `en` and remains on the same state.\n *\n * ```html\n * <a ui-sref=\"{ lang: 'en' }\">English</a>\n * ```\n *\n * - A middle-click, right-click, or ctrl-click is handled (natively) by the browser to open the href in a new window, for example.\n *\n * - Unlike the parameter values expression, the state name is not `$watch`ed (for performance reasons).\n * If you need to dynamically update the state being linked to, use the fully dynamic [[uiState]] directive.\n

This allows a state to create relative `ui-state` which always targets the same destination.\n *\n * ### hrefs\n * If the linked state has a URL, the directive will automatically generate and\n * update the `href` attribute (using the [[StateService.href]] method).\n *\n * ### Parameter Values\n * In addition to the state name expression, a `ui-state` can include parameter values which are applied when activating the state.\n * Param values should be provided using the `ui-state-params` attribute.\n * The `ui-state-params` attribute value is `$watch`ed and evaluated as an expression.\n *\n * #### Example:\n * This example renders a list of links with param values.\n * The state's `userId` parameter value comes from each user's `user.id` property.\n * ```html\n * <li ng-repeat=\"link

pass to [[StateService.go]] by using the `ui-state-opts` attribute.\n * Options are restricted to `location`, `inherit`, and `reload`.\n * The value of the `ui-state-opts` is `$watch`ed and evaluated as an expression.\n *\n * #### Example:\n * ```html\n * <a ui-state=\"returnto.state\" ui-state-opts=\"{ reload: true }\">Home</a>\n * ```\n *\n * ### Other DOM Events\n *\n * You can also customize

when a `ui-sref` is active\n *\n * A directive working alongside [[uiSref]] and [[uiState]] to add classes to an element when the\n * related directive's state is active (and remove them when it is inactive).\n *\n * The primary use-case is to highlight the active link in navigation menus,\n * distinguishing it from the inactive menu items.\n *\n * ### Linking to a `ui-sref` or `ui-state`\n * `ui-sref-active` can live on the same element as `ui-sref`/`ui-state`, or it can be on a parent element.\n * 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**.\n *\n * ### Matching\n *\n * The `ui-sref-active` directive applies the CSS class when the `ui-sref`/`ui-state`'s target state **or any child state is active**.\n * This is a \"fuzzy match\" which uses [[StateService.includes]].\n *\n * 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).\n * This is an \"exact match\" which uses [[StateService.is]].\n *\n * ### Parameter values\n * 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.\n * This allows a list of links to the same state with different parameters to be rendered, and the correct one highlighted.\n *\n * #### Example:\n * ```html\n * <li ng-repeat=\"user in users\" ui-sref-active=\"active\">\n * <a ui-sref=\"user.details({ userId: user.id })\">{{ user.lastName }}</a>\n * </li>\n * ```\n *\n * ### Examples\n *\n * Given the following template:\n * #### Example:\n * ```html\n * <ul>\n * <li ui-sref-active=\"active\" class=\"item\">\n * <a href ui-sref=\"app.user({user: 'bilbobaggins'})\">@bilbobaggins</a>\n * </li>\n * </ul>\n * ```\n *\n * When the app state is `app.user` (or any child state),\n * and contains the state parameter \"user\" with value \"bilbobaggins\",\n * the resulting HTML will appear as (note the 'active' class):\n *\n * ```html\n * <ul>\n * <li ui-sref-active=\"active\" class=\"item active\">\n * <a ui-sref=\"app.user({user: 'bilbobaggins'})\" href=\"/users/bilbobaggins\">@bilbobaggins</a>\n * </li>\n * </ul>\n * ```\n *\n * ### Glob mode\n *\n * It is possible to pass `ui-sref-active` an expression that evaluates to an object.\n * The objects keys represent active class names and values represent the respective state names/globs.\n * `ui-sref-active` will match if the current active state **includes** any of\n * the specified state names/globs, even the abstract ones.\n *\n * #### Example:\n * Given the following template, with \"admin\" being an abstract state:\n * ```html\n * <div ui-sref-active=\"{'active': 'admin.**'}\">\n * <a ui-sref-active=\"active\" ui-sref=\"admin.roles\">Roles</a>\n * </div>\n * ```\n *\n * Arrays are also supported as values in the `ngClass`-like interface.\n * This allows multiple states to add `active` class.\n *\n * #### Example:\n * Given the following template, with \"admin.roles\" being the current state, the class will be added too:\n * ```html\n * <div ui-sref-active=\"{'active': ['owner.**', 'admin.**']}\">\n * <a ui-sref-active=\"active\" ui-sref=\"admin.roles\">Roles</a>\n * </div>\n * ```\n *\n * When the current state is \"admin.roles\" the \"active\" class will be applied to both the `<div>` and `<a>` elements.\n * It is important to note that the state names/globs passed to `ui-sref-active` override any state provided by a linked `ui-sref`.\n *\n * ### Notes:\n *\n * - The class name is interpolated **once** during the directives link time (any further changes to the\n * interpolated value are ignored).\n *\n * - Multiple classes may be specified in a space-separated format: `ui-sref-active='class1 class2 class3'`\n */\nlet uiSrefActiveDirective: ng1_directive;\nuiSrefActiveDirective = [\n '$state',\n '$stateParams',\n

When it evaluates to true, the `ui-view` will be scrolled into view when it is activated.\n * Uses [[$uiViewScroll]] to do the scrolling.\n *\n * - `onload`: Expression to evaluate whenever the view updates.\n *\n * #### Example:\n * A view can be unnamed or named.\n * ```html\n * <!-- Unnamed -->\n * <div ui-view></div>\n *\n * <!-- Named -->\n * <div ui-view=\"viewName\"></div>\n *\n * <!-- Named (different style) -->\n * <ui-view name=\"viewName\"></ui-view>\n * ```\n *\n * You can only have one unnamed view within any template (or root html). If you are only using a\n * single view and it is unnamed then you can populate it like so:\n *\n * ```html\n * <div ui-view></div>\n * $stateProvider.state(\"home\", {\n * template: \"<h1>HELLO!</h1>\"\n * })\n * ```\n *\n * The above is a convenient shortcut equivalent to specifying your view explicitly with the\n * [[Ng1StateDeclaration.views]] config property, by name, in this case an empty name:\n *\n * ```js\n * $stateProvider.state(\"home\", {\n * views: {\n * \"\": {\n * template: \"<h1>HELLO!</h1>\"\n * }\n * }\n * })\n * ```\n *\n * But typically you'll only use the views property if you name your view or have more than one view\n * in the same template. There's not really a compelling reason to name a view if its the only one,\n * but you could if you wanted, like so:\n *\n * ```html\n * <div ui-view=\"main\"></div>\n * ```\n *\n * ```js\n * $stateProvider.state(\"home\", {\n * views: {\n * \"main\": {\n * template: \"<h1>HELLO!</h1>\"\n * }\n * }\n * })\n * ```\n *\n * Really though, you'll use views to set up multiple views:\n *\n * ```html\n * <div ui-view></div>\n * <div ui-view=\"chart\"></div>\n * <div ui-view=\"data\"></div>\n * ```\n *\n * ```js\n * $stateProvider.state(\"home\", {\n * views: {\n * \"\": {\n * template: \"<h1>HELLO!</h1>\"\n * },\n * \"chart\": {\n * template: \"<chart_thing/>\"\n * },\n * \"data\": {\n * template: \"<data_thing/>\"\n * }\n * }\n * })\n * ```\n *\n * #### Examples for `autoscroll`:\n * ```html\n * <!-- If autoscroll present with no expression,\n * then scroll ui-view into view -->\n * <ui-view autoscroll/>\n *\n * <!-- If autoscroll present with valid expression,\n * then scroll ui-view into view if expression evaluates to true -->\n * <ui-view autoscroll='true'/>\n * <ui-view autoscroll='false'/>\n * <ui-view autoscroll='scopeVariable'/>\n * ```\n *\n * Resolve data:\n *\n * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this\n * can be customized using [[Ng1ViewDeclaration.resolveAs]]). This can be then accessed from the template.\n *\n * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the\n * controller is instantiated. The `$onInit()` hook can be used to perform initialization code which\n * depends on `$resolve` data.\n *\n * #### Example:\n * ```js\n * $stateProvider.state('home', {\n * template: '<my-component user=\"$resolve.user\"></my-component>',\n * resolve: {\n * user: function(UserService) { return UserService.fetchUser(); }\n * }\n * });\n * ```\n */\nexport let uiView: ng1_directive;\nuiView = [\n
