Constructor Detail

• SimpleEventBus

  public SimpleEventBus()

• SimpleEventBus

  @Deprecated
  protected SimpleEventBus(boolean fireInReverseOrder)

  Deprecated. This is a legacy feature, required by GWT's old HandlerManager. Reverse order is not honored for handlers tied to a specific event source (via addHandlerToSource(com.google.web.bindery.event.shared.Event.Type<H>, java.lang.Object, H).
  Allows creation of an instance that fires its handlers in the reverse of the order in which they were added, although filtered handlers all fire before unfiltered handlers.

Method Detail

• addHandler

  public <H> HandlerRegistration addHandler(Event.Type<H> type,
                                   H handler)

  Description copied from class: EventBus
  Adds an unfiltered handler to receive events of this type from all sources.

  It is rare to call this method directly. More typically an Event subclass will provide a static register method, or a widget will accept handlers directly.

  Specified by:

  addHandler in class EventBus

  Type Parameters:

  H - The type of handler

  Parameters:

  type - the event type associated with this handler

  handler - the handler

  Returns:

  the handler registration, can be stored in order to remove the handler later

• addHandlerToSource

  public <H> HandlerRegistration addHandlerToSource(Event.Type<H> type,
                                           java.lang.Object source,
                                           H handler)

  Description copied from class: EventBus
  Adds a handler to receive events of this type from the given source.

  It is rare to call this method directly. More typically a Event subclass will provide a static register method, or a widget will accept handlers directly.

  Specified by:

  addHandlerToSource in class EventBus

  Type Parameters:

  H - The type of handler

  Parameters:

  type - the event type associated with this handler

  source - the source associated with this handler

  handler - the handler

  Returns:

  the handler registration, can be stored in order to remove the handler later

• fireEvent

  public void fireEvent(Event<?> event)

  Description copied from class: EventBus
  Fires the event from no source. Only unfiltered handlers will receive it.

  Any exceptions thrown by handlers will be bundled into a UmbrellaException and then re-thrown after all handlers have completed. An exception thrown by a handler will not prevent other handlers from executing.

  Specified by:

  fireEvent in class EventBus

  Parameters:

  event - the event to fire

• fireEventFromSource

  public void fireEventFromSource(Event<?> event,
                         java.lang.Object source)

  Description copied from class: EventBus
  Fires the given event to the handlers listening to the event's type.

  Any exceptions thrown by handlers will be bundled into a UmbrellaException and then re-thrown after all handlers have completed. An exception thrown by a handler will not prevent other handlers from executing.

  Specified by:

  fireEventFromSource in class EventBus

  Parameters:

  event - the event to fire
