Constructor Detail

### PlaceController

    @Deprecated
    public PlaceController(EventBus eventBus)

### PlaceController

    @Deprecated
    public PlaceController(EventBus eventBus,
                                      PlaceController.Delegate delegate)

  Deprecated. use `PlaceController(EventBus, Delegate)`

  Legacy method tied to the old location for `EventBus`.

### PlaceController

    public PlaceController(EventBus eventBus)

  Create a new PlaceController with a `PlaceController.DefaultDelegate`. The DefaultDelegate is created via a call to GWT.create(), so an alternative default implementation can be provided through <replace-with> rules in a `.gwt.xml` file.

  Parameters:
    `eventBus` - the `EventBus`

### PlaceController

    public PlaceController(EventBus eventBus,
                           PlaceController.Delegate delegate)

  Create a new PlaceController.

  Parameters:
    `eventBus` - the `EventBus`
    `delegate` - the `PlaceController.DefaultDelegate` in charge of Window-related events

Method Detail

### getWhere

    public Place getWhere()

  Returns the current place.

  Returns:
    a `Place` instance

### goTo

    public void goTo(Place newPlace)

  Request a change to a new place. It is not a given that we'll actually get there. First a `PlaceChangeRequestEvent` will be posted to the event bus. If any receivers post a warning message to that event, it will be presented to the user via `PlaceController.DefaultDelegate.confirm(String)` (which is typically a call to `Window.confirm(String)`). If she cancels, the current location will not change. Otherwise, the location changes and a `PlaceChangeEvent` is posted announcing the new place.

  Parameters:
    `newPlace` - a `Place` instance

### log

    java.util.logging.Logger log()

  Visible for testing.
