Interface HandlerRegistration

public interface HandlerRegistration

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

To use com.google.web.bindery.event.shared.HandlerRegistration or com.google.gwt.event.shared.HandlerRegistration in a context where a org.gwtproject.web.bindery.event.shared.HandlerRegistration is needed, or the reverse, use handlerRegistration::removeHandler.

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();
  }
 };
