Constructor Detail

DecoratingObservableSet

public DecoratingObservableSet(
IObservableSet decorated,
                               boolean disposeDecoratedOnDispose)
Constructs a DecoratingObservableSet which decorates the given observable.

Parameters:
decorated - the observable set being decorated
disposeDecoratedOnDispose -
Method Detail

clear

public void clear()
Specified by:
clear in interface Collection
Specified by:
clear in interface Set
Overrides:
clear in class DecoratingObservableCollection

addSetChangeListener

public void addSetChangeListener(
ISetChangeListener listener)
Specified by:
addSetChangeListener in interface IObservableSet

removeSetChangeListener

public void removeSetChangeListener(
ISetChangeListener listener)
Specified by:
removeSetChangeListener in interface IObservableSet

fireSetChange

protected void fireSetChange(
SetDiff diff)

fireChange

protected void fireChange()
Overrides:
fireChange in class AbstractObservable

firstListenerAdded

protected void firstListenerAdded()
Overrides:
firstListenerAdded in class DecoratingObservable

lastListenerRemoved

protected void lastListenerRemoved()
Overrides:
lastListenerRemoved in class DecoratingObservable

handleSetChange

protected void handleSetChange(
SetChangeEvent event)
Called whenever a SetChangeEvent is received from the decorated observable. By default, this method fires the set change event again, with the decorating observable as the event source. Subclasses may override to provide different behavior.

Parameters:
event - the change event received from the decorated observable

Object listenerType,
                           
IObservablesListener listener)
Parameters:
listenerType -
