HandlerRegistration (GWT Javadoc)

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();
  }
 };
 
```
