append back to summary

append	back to summary
public EventDispatchChain append(final EventDispatcher eventDispatcher) Implements javafx.event.EventDispatchChain.append. Doc from javafx.event.EventDispatchChain.append. Appends the specified `EventDispatcher` to this chain. Returns a reference to the chain with the appended element. The caller shouldn't assume that this `EventDispatchChain` remains unchanged nor that the returned value will reference a different chain after the call. All this depends on the `EventDispatchChain` implementation. So the call should be always done in the following form: `chain = chain.append(eventDispatcher);` Annotations @Override

public EventDispatchChain append(final EventDispatcher eventDispatcher)

Implements javafx.event.EventDispatchChain.append.

The caller shouldn't assume that this EventDispatchChain remains unchanged nor that the returned value will reference a different chain after the call. All this depends on the EventDispatchChain implementation.

dispatchEvent	back to summary
public Event dispatchEvent(final Event event) Implements javafx.event.EventDispatchChain.dispatchEvent. Doc from javafx.event.EventDispatchChain.dispatchEvent. Dispatches the specified event through this `EventDispatchChain`. The return value represents the event after processing done by the chain. If further processing is to be done after the call the event referenced by the return value should be used instead of the original event. In the case the event is fully handled / consumed in the chain the returned value is `null` and no further processing should be done with that event. Annotations @Override
