• 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.Delegate 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.Delegate.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.
