export interface Ng2StateDeclaration<T = unknown> extends StateDeclaration, Ng2ViewDeclaration<T> {
    /**
     * An optional object used to define multiple named views.
     *
     * Each key is the name of a view, and each value is a [[Ng2ViewDeclaration]].
     * Unnamed views are internally renamed to `$default`.
     *
     * A view's name is used to match an active `<ui-view>` directive in the DOM.  When the state
     * is entered, the state's views are activated and then matched with active `<ui-view>` directives:
     *
     * - The view's name is processed into a ui-view target:
     *   - ui-view address: an address to a ui-view
     *   - state anchor: the state to anchor the address to
     *
     *  Examples:
     *
     *  Targets three named ui-views in the parent state's template
     *
     * #### Example:
     * ```js
     * views: {
     *   header: {component: HeaderComponent},
     *   body: {component: BodyComponent},
     *   footer: {component: FooterComponent}
     * }
     * ```
     *
     * #### Example:
     * ```js
     * // Targets named ui-view="header" in the template of the ancestor state 'top'
     * // and the named `ui-view="body" from the parent state's template.
     * views: {
     *   'header@top': {component: MsgHeaderComponent},
     *   'body': {component: MessagesComponent}
     * }
     * ```
     *
     * ## View targeting details
     *
     * There are a few styles of view addressing/targeting.  The most common is a simple `ui-view` name
     *
     *
     * #### Simple ui-view name
     *
     * Addresses without an `@` are anchored to the parent state.
     *
     * #### Example:
     * ```js
     * // target the `<div ui-view='foo'></div>` created in the parent state's view
     * views: { foo: {...} }
     * ```
     *
     * #### View name anchored to a state
     *
     * You can anchor the `ui-view` name to a specific state by including an `@`
     *
     * @example
     *
     * ```js
     *
     * // target the `<div ui-view='foo'></div>` which was created in a
     * // view owned by the state `bar.baz`
     * views: { 'foo@bar.baz': {...} }
     * ```
     *
     * #### Absolute addressing
     *
     * You can address a `ui-view` absolutely, using dotted notation, by prefixing the address with a `!`.  Dotted
     * addresses map to the hierarchy of `ui-view`s active in the DOM:
     *
     * #### Example:
     * ```js
     * // absolutely target the `<div ui-view='nested'></div>`... which was created
     * // in the unnamed/$default root `<ui-view></ui-view>`
     * views: { '!$default.nested': {...} }
     * ```
     *
     * #### Relative addressing
     *
     * Absolute addressing is actually relative addressing, only anchored to the unnamed root state.  You can also use
     * relative addressing anchored to any state, in order to target a target deeply nested `ui-views`:
     *
     * #### Example:
     * ```js
     *
     * // target the `<div ui-view='bar'></div>`... which was created inside the
     * // `<div ui-view='bar'></div>`... which was created inside the parent state's template.
     * views: { 'foo.bar': {...} }
     * ```
     *
     * #### Example:
     * ```js
     * // target the `<div ui-view='bar'></div>`...  which was created in
     * // `<div ui-view='foo'></div>`... which was created in a template crom the state `baz.qux`
     * views: { 'foo.bar@baz.qux': {...} }
     *
     * ---
     *
     * ## State `component:` and `views:` incompatiblity
     *
     * If a state has a `views` object, the state-level `component:` property is ignored.  Therefore,
     * if _any view_ for a state is declared in the `views` object, then _all of the state's views_ must be defined in
     * the `views` object.

     *     header: NavBar,
     *     content: ContactList
     *   }
     * }
     * ```
     *
     * ### Accessing Resolve Data
     *
     * The component can access the Transition's [[Ng2StateDeclaration.resolve]] data in one of two ways:
     *
     * 1) Using Dependency Injection in the component constructor
     *
     * (using Typescript)
     * ```js
     * class MyComponent {
     *   constructor(@Inject("myResolveData") public resolveValueA, resolveValueB: public SomeClass) {
     *   }
     * }
     * ```
     *
     * (using ES6/7/babel)
     * ```js
     * class MyComponent {
     *   static get parameters() {
     *     return [["myResolveData"], [MyResolveClass]];
     *   }
     *   constructor(resolveValueA, resolveValueB) {
     *     this.resolveValueA = resolveValueA;
     *     this.resolveValueB = resolveValueB;
     *   }
     * }
     * ```
     *
     * See also: https://github.com/shuhei/babel-plugin-angular2-annotations
     *
     * 2) Using a component input
     *
     * Note: To bind a resolve to a component input, the resolves must `provide:` a string value
     *
     * ```js
     * @Component() {
     *   inputs: ['resolveValueA']
     * }
     * class MyComponent {
     *   myResolveValueA;
     *   @Input() resolveValueB;
     *   @Input("resolveValueC") resolveValueC;
     *
     *   constructor() {
     *   }
     * }
     * ```
     */
    component?: Type<T>;
    /**
     * An object which maps `resolve` keys to [[component]] `bindings`.
     *
     * A property of [[Ng2StateDeclaration]] or [[Ng2ViewDeclaration]]:
     *
     * When using a [[component]] declaration (`component: MyComponent`), each input binding for the component is supplied
     * data from a resolve of the same name, by default.  You may supply data from a different resolve name by mapping it here.
     * This might be useful if you want to reuse the same resolve value with various components with different input binding names.
     *
     * Each key in this object is the name of one of the component's input bindings.
     * Each value is the name of the resolve that should be provided to that binding.
     *
     * Any component bindings that are omitted from this map get the default behavior of mapping to a resolve of the * same name.

     *   name: 'foo',
     *   component: MyComponent,
