I like the EventDispatcher class from ActionScript 3 so I decided to write one for Java.
Usage
1 2 3 4 5 6 7 | foo.addEventListener("MyEvent", new EventListener() { public void run(Event event) { // remove the listener if no longer needed event.target.removeEventlistener(event.type, this); // do stuff } } |
Now your class can either extend EventDispatcherImp or implement EventDispatcher and you’re ready to dispatch events.
Via inheritance
1 2 3 | import com.wumedia.events.EventDispatcher.EventDispatcherImpl; public class Dispatcher extends EventDispatcherImpl { } |
Via composition
1 2 3 4 5 6 | import com.wumedia.events.EventDispatcher.EventDispatcherImpl; public class Dispatcher implements EventDispatcher { public Dispatcher() { _dispatcher = new EventDispatcherImpl(this); } } |
)
