- ComputedSet
public abstract class AbstractObservableSet
- extends AbstractObservable
- implements IObservableSet
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.

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
- 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:
fireChange
in class AbstractObservable
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
