public void fireValueChangedEvent()
Fires notifications to all attachedInvalidationListeners,ChangeListeners, andMultisetChangeListeners.
-
fireValueChangedEvent
public void fireValueChangedEvent(MultisetChangeListener.Change<? extends E> change)
Fires notifications to all attachedInvalidationListeners, andMultisetChangeListeners.- Overrides:
fireValueChangedEventin classMultisetListenerHelper<E>- Parameters:
change- The change that needs to be propagated.
-
removeListener
public void removeListener(javafx.beans.value.ChangeListener<? super ObservableMultiset<E>> listener)
