All Known Subinterfaces:

All Known Implementing Classes:

public interface HandlerRegistration

Registration objects returned when an event handler is bound (e.g. via EventBus.addHandler(com.google.web.bindery.event.shared.Event.Type<H>, H)), used to deregister.

A tip: to make a handler deregister itself try something like the following:

new MyHandler() {
  HandlerRegistration reg = MyEvent.register(eventBus, this);
 
  public void onMyThing(MyEvent event) {
    /* do your thing */
    reg.removeHandler();
  }
 };
