org.eclipse.core.databinding.observable.set.ObservableSet<E>
org.eclipse.core.databinding.observable.set.UnionSet<E>
- Type Parameters:
E
- type of the elements in the union set
- All Implemented Interfaces:
Iterable<E>
,Collection<E>
,Set<E>
,IObservable
,IObservableCollection<E>
,IObservableSet<E>
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.

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 interfaceIObservable
- Overrides:
isStale
in classObservableSet<E>
- Returns:
- Returns the stale state.
