      • dispatch

        protected void dispatch​(IObservablesListener listener)
        Description copied from class: ObservableEvent
        Dispatch this event to the given listener. Subclasses must implement this method by calling the appropriate type-safe event handling method on the given listener according to the type of this event.

        dispatch in class ObservableEvent
        Parameters:
        listener - the listener that should handle the event

      • getListenerType

        protected java.lang.Object getListenerType()
        Description copied from class: ObservableEvent

        Specified by:
        getListenerType in class ObservableEvent
        Returns:
        a unique object representing the concrete type of this event.
