Constructor Detail

SetMultimapExpressionHelper

public SetMultimapExpressionHelper(ObservableSetMultimapValue<K,V> observableValue)

Constructs a new SetMultimapExpressionHelper for the given source ObservableSetMultimapValue.

Parameters:

observableValue - The observableValue ObservableSetMultimap, which is used in change notifications.

Method Detail

addListener

public void addListener(javafx.beans.value.ChangeListener<? super ObservableSetMultimap<K,V>> listener)

Parameters:

listener - The listener to add.

fireValueChangedEvent

public void fireValueChangedEvent()

Fires notifications to all attached InvalidationListeners, ChangeListeners, and SetMultimapChangeListeners.

fireValueChangedEvent

public void fireValueChangedEvent(SetMultimapChangeListener.Change<? extends K,? extends V> change)

Fires notifications to all attached InvalidationListeners, ChangeListeners, and SetMultimapChangeListeners.

Overrides:

fireValueChangedEvent in class SetMultimapChangeListenerHelper<K,V>

Parameters:

change - The change that needs to be propagated.

removeListener

public void removeListener(javafx.beans.value.ChangeListener<? super ObservableSetMultimap<K,V>> listener)

Removes the given ChangeListener from this SetMultimapChangeListener. If its was registered more than once, removes one occurrence.

Parameters:

listener - The listener to remove.
