Class AbstractObservableSet<E>
java.lang.Object
org.eclipse.core.databinding.observable.AbstractObservable
org.eclipse.core.databinding.observable.set.AbstractObservableSet<E>
- Type Parameters:
E
- the type of the elements in this set
- All Implemented Interfaces:
Iterable<E>
,Collection<E>
,Set<E>
,IObservable
,IObservableCollection<E>
,IObservableSet<E>
- Direct Known Subclasses:
ComputedSet
public abstract class AbstractObservableSet<E>
extends AbstractObservable
implements IObservableSet<E>
Abstract implementation of
IObservableSet
.
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
- Implementation Note:
- If methods are added to the interface which this class implements then implementations of those methods must be added to this class.

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
- Returns:
- Returns the stale state.
-
setStale
public void setStale(boolean stale) - Parameters:
stale
- The stale state to set. This will fire a stale event if the given boolean is true and this observable set was not already stale.
-
fireChange
protected void fireChange()- Overrides:

-
addListener
- Parameters:
listenerType
- arbitrary object to identify a type of the listenerlistener
- the listener to add; notnull
-
removeListener
- Parameters:
listenerType
- arbitrary object to identify a type of the listenerlistener
- the listener to remove; notnull
