- 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:

java.lang.Iterable<E>, java.util.Collection<E>, java.util.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.

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
    
    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

  - addListener
```
protected void addListener(java.lang.Object listenerType,

    Parameters:
    
    listenerType - arbitrary object to identify a type of the listener
    
    listener - the listener to add; not null
  - removeListener
```
protected void removeListener(java.lang.Object listenerType,
                              IObservablesListener listener)
