Class EventDispatcherImpl

  • All Implemented Interfaces:
    Direct Known Subclasses:
    I2PTunnel, I2PTunnelTask

    public class EventDispatcherImpl
    extends Object
    implements EventDispatcher
    An implementation of the EventDispatcher interface. Since Java doesn't support multiple inheritance, you could follow the style: this class should be instantiated and kept as a variable by each object it is used by, ala: private final EventDispatcher _event = new EventDispatcher(); Deprecated - Used only by I2PTunnel If there is anything in here that doesn't make sense, turn off your computer and go fly a kite - (c) 2004 by jrandom

        public void attachEventDispatcher​(EventDispatcher ev)
        Description copied from interface: EventDispatcher
        Attach an EventDispatcher object to the events dispatching chain. Note that notification is not bidirectional (i.e. events notified to ev won't reach the object calling this method). Good luck, and beware of notification loops! :-)
