This can be used \n * to add custom functionality to ui-router, for example inferring templateUrl \n * based on the state name.\n *\n * When passing only a name, it returns the current (original or decorated) builder\n * function that matches `name`.\n *\n * The builder functions that can be decorated are listed below. Though not all\n * necessarily have a good use case for decoration, that is up to you to decide.\n *\n * In addition, users can attach custom decorators, which will generate new \n * properties within the state's internal definition. There is currently no clear \n * use-case for this beyond accessing internal states (i.e. $state.$current), \n * however, expect this to become increasingly relevant as we introduce additional \n * meta-programming features.\n *\n * **Warning**: Decorators should not be interdependent because the order of \n * execution of the builder functions in non-deterministic. Builder functions \n * should only be dependent on the state definition object and super function.\n *\n *\n * Existing builder functions and current return values:\n *\n * - **parent** `{object}` - returns the parent state object.\n * - **data** `{object}` - returns state data, including any inherited data that is not\n * overridden by own values (if any).\n * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}\n * or `null`.\n * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is \n * navigable).\n * - **params** `{object}` - returns an array of state params that are ensured to \n * be a super-set of parent's params.\n * - **views** `{object}` - returns a views object where each key is an absolute view \n * name (i.e. \"viewName@stateName\") and each value is the config object \n * (template, controller) for the view. Even when you don't use the views object \n * explicitly on a state config, one is still created for you internally.\n * So by decorating this builder function you have access to decorating template \n * and controller properties.\n * - **ownParams** `{object}` - returns an array of params that belong to the state, \n * not including any params defined by ancestor states.\n * - **path** `{string}` - returns the full path from the root down to this state. \n * Needed for state activation.\n * - **includes** `{object}` - returns an object that includes every state that \n * would pass a `$state.includes()` test.\n *\n * @example\n * \n * // Override the internal 'views' builder with a function that takes the state\n * // definition, and a reference to the internal function being overridden:\n * $stateProvider.decorator('views', function (state, parent) {\n * var result = {},\n * views = parent(state);\n *\n * angular.forEach(views, function (config, name) {\n * var autoName = (state.name + '.' + name).replace('.', '/');\n * config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';\n * result[name] = config;\n * });\n * return result;\n * });\n *\n * $stateProvider.state('home', {\n * views: {\n * 'contact.list': { controller: 'ListController' },\n * 'contact.item': { controller: 'ItemController' }\n * }\n * });\n *\n * // ...\n *\n * $state.go('home');\n * // Auto-populates list and item views with /partials/home/contact/list.html,\n * // and /partials/home/contact/item.html, respectively.\n * \n *\n * @param {string} name The name of the builder function to decorate. \n * @param {object} func A function that is responsible for decorating the original \n * builder function.
