MapExpressionHelperEx

public MapExpressionHelperEx(javafx.beans.value.ObservableMapValue<K,V> observableValue)

Constructs a new MapExpressionHelperEx for the given source ObservableMapValue.

Parameters:

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

Method Detail

addListener

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

Adds a new ChangeListener to this MapExpressionHelperEx. If the same listener is added more than once, it will be registered more than once and will receive multiple change events.

Parameters:

listener - The ChangeListener to add.

fireValueChangedEvent

public void fireValueChangedEvent()

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

fireValueChangedEvent

public void fireValueChangedEvent(javafx.collections.MapChangeListener.Change<? extends K,? extends V> change)

Fires notifications to all attached InvalidationListeners, and MapChangeListeners.

Overrides:

fireValueChangedEvent in class MapListenerHelperEx<K,V>

Parameters:

change - The change that needs to be propagated.

removeListener

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

Removes the given ChangeListener from this MapChangeListener. If it was registered more than once, removes only one occurrence.

Parameters:

listener - The ChangeListener to remove.
