Constructor Detail

SetMultimapListenerHelper

public SetMultimapListenerHelper(ObservableSetMultimap<K,V> source)

Constructs a new SetMultimapListenerHelper for the given source ObservableSetMultimap.

Parameters:

source - The ObservableSetMultimap to use as source in change notifications.

Method Detail

addListener

public void addListener(InvalidationListener listener)

Adds a new InvalidationListener to this SetMultimapListenerHelper. 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 listener to add.

addListener

public void addListener(SetMultimapChangeListener<? super K,? super V> listener)

Adds a new SetMultimapChangeListener to this SetMultimapListenerHelper. 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 listener to add.

fireValueChangedEvent

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

Notifies all attached InvalidationListeners and SetMultimapChangeListeners about the change.

Parameters:

change - The change to notify listeners about.

getSource

protected ObservableSetMultimap<K,V> getSource()

Returns the source ObservableSetMultimap this SetMultimapListenerHelper is bound to, which is used in change notifications.

Returns:

The source ObservableSetMultimap.

notifyInvalidationListeners

protected void notifyInvalidationListeners()

Notifies all registered InvalidationListeners.

notifySetMultimapChangeListeners

protected void notifySetMultimapChangeListeners(SetMultimapChangeListener.Change<? extends K,? extends V> change)

Notifies the attached SetMultimapChangeListeners about the related change.

Parameters:

change - The applied change.

removeListener

public void removeListener(InvalidationListener listener)

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

Parameters:

listener - The listener to remove.

removeListener

public void removeListener(SetMultimapChangeListener<? super K,? super V> listener)

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

Parameters:

listener - The listener to remove.
