Package com.google.web.bindery.event.shared

## Interface HandlerRegistration

- All Known Subinterfaces:
    `HandlerRegistration`
  All Known Implementing Classes:
    `LegacyHandlerWrapper`

      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();
        }
       };
