org.eclipse.core.databinding.observable.set
Class UnionSet

java.lang.Object
  extended by 

org.eclipse.core.databinding.observable.AbstractObservable
      extended by 

org.eclipse.core.databinding.observable.set.ObservableSet
          extended by 
org.eclipse.core.databinding.observable.set.UnionSet
All Implemented Interfaces:
Iterable, Collection, Set, IObservable, IObservableCollection, IObservableSet

public final class UnionSet
extends ObservableSet

Represents a set consisting of the union of elements from one or more other sets. This object does not need to be explicitly disposed. If nobody is listening to the UnionSet, the set will remove its listeners.

This class is thread safe. All state accessing methods must be invoked from the current realm. Methods for adding and removing listeners may be invoked from any thread.

Since:
1.0

Method Detail

isStale

public boolean isStale()
Description copied from interface: IObservable
Returns whether the state of this observable is stale and is expected to change soon. A non-stale observable that becomes stale will notify its stale listeners. A stale object that becomes non-stale does so by changing its state and notifying its change listeners, it does not notify its stale listeners about becoming non-stale. Clients that do not expect asynchronous changes may ignore staleness of observable objects.

Specified by:
isStale in interface IObservable
Overrides:
isStale in class ObservableSet
Returns:
Returns the stale state.

firstListenerAdded

protected void firstListenerAdded()

lastListenerRemoved

protected void lastListenerRemoved()

getterCalled

protected void getterCalled()
Overrides:
getterCalled in class ObservableSet

addListener

protected void addListener(
Object listenerType,
                           
IObservablesListener listener)
Parameters:
listenerType -
listener -

removeListener

protected void removeListener(
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 
Object clone()
                throws 
CloneNotSupportedException
Overrides:
clone in class Object
Throws:
CloneNotSupportedException
