+ * Convenience method for transitioning to a new state. `$state.go` calls
+ * `$state.transitionTo` internally but automatically sets options to
+ * `{ location: true, inherit: true, relative: $state.$current, notify: true }`.
+ * This allows you to easily use an absolute or relative to path and specify
+ * only the parameters you'd like to update (while letting unspecified parameters
+ * inherit from the currently active ancestor states).
+ *
+ * @example
+ *
+ * var app = angular.module('app', ['ui.router']);
+ *
+ * app.controller('ctrl', function ($scope, $state) {
+ * $scope.changeState = function () {
+ * $state.go('contact.detail');

+ * - `$state.go('contact.detail')` - will go to the `contact.detail` state
+ * - `$state.go('^')` - will go to a parent state
+ * - `$state.go('^.sibling')` - will go to a sibling state
+ * - `$state.go('.child.grandchild')` - will go to grandchild state
+ *
+ * @param {object=} params A map of the parameters that will be sent to the state,
+ * will populate $stateParams. Any parameters that are not specified will be inherited from currently
+ * defined parameters. Only parameters specified in the state definition can be overridden, new
+ * parameters will be ignored. This allows, for example, going to a sibling state that shares parameters
+ * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
+ * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
+ * will get you all current parameters, etc.
+ * @param {object=} options Options object. The options are:
+ *
+ * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
+ * will not. If string, must be `"replace"`, which will update url and also replace last history record.
+ * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
+ * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'),
+ * defines which state to be relative from.
+ * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
+ * - **`reload`** (v0.2.5) - {boolean=false|string|object}, If `true` will force transition even if no state or params
+ * have changed. It will reload the resolves and views of the current state and parent states.
+ * If `reload` is a string (or state object), the state object is fetched (by name, or object reference); and \
+ * the transition reloads the resolves and views for that matched state, and all its children states.
+ *
+ * @returns {promise} A promise representing the state of the new transition.
+ *
+ * Possible success values:
+ *
+ * - $state.current
+ *
+ * Possible rejection values: + * + * - 'transition superseded' - when a newer transition has been started after this one + * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener + * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or + * when a `$stateNotFound` `event.retry` promise errors. + * - 'transition failed' - when a state has been unsuccessfully found after 2 tries. + * - *resolve error* - when an error has occurred with a `resolve` + * + */ + $state.go = function go(to, params, options) { + return $state.transitionTo(to, params, extend({ inherit: true, relative: $state.$current }, options)); + }; + + /** + * @ngdoc function + * @name ui.router.state.$state#transitionTo + * @methodOf ui.router.state.$state + * + * @description + * Low-level method for transitioning to a new state. {@link ui.router.state.$state#methods_go $state.go} + * uses `transitionTo` internally. `$state.go` is recommended in most situations. + * + * @example + *

+ * - **`lossy`** - {boolean=true} - If true, and if there is no url associated with the state provided in the
+ * first parameter, then the constructed href url will be built from the first navigable ancestor (aka
