DecoratingObservableSet

public DecoratingObservableSet(IObservableSet<E> 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 java.util.Collection<E>

Specified by:

clear in interface java.util.Set<E>

Overrides:

clear in class DecoratingObservableCollection<E>

addSetChangeListener

public void addSetChangeListener(ISetChangeListener<? super E> listener)

Specified by:

addSetChangeListener in interface IObservableSet<E>

removeSetChangeListener

public void removeSetChangeListener(ISetChangeListener<? super E> listener)

Specified by:

removeSetChangeListener in interface IObservableSet<E>

fireSetChange

protected void fireSetChange(SetDiff<E> 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<? extends E> 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

dispose

public void dispose()

Description copied from interface: IObservable

Disposes of this observable object, removing all listeners registered with this object, and all listeners this object might have registered on other objects.

Specified by:

dispose in interface IObservable

Overrides:

dispose in class DecoratingObservableCollection<E>

addListener

protected void addListener(java.lang.Object listenerType,
                           IObservablesListener listener)

Parameters:

listenerType -

listener -

removeListener

protected void removeListener(java.lang.Object listenerType,
                              IObservablesListener listener)

Parameters:

listenerType -

listener -

hasListeners

protected boolean hasListeners()

fireEvent

protected void fireEvent(ObservableEvent event)

getRealm

public Realm getRealm()

Returns:

Returns the realm.

clone

protected java.lang.Object clone()
                          throws java.lang.CloneNotSupportedException

Overrides:

clone in class java.lang.Object
