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.
setWrappedSet
protected void setWrappedSet(Set wrappedSet)
- Parameters:
wrappedSet
- The wrappedSet to set.
fireChange
protected void fireChange()
- Overrides:
fireChange
in class AbstractObservable
dispose
public void dispose()
- Description copied from interface:
IObservable
- Disposes of this observable object, removing all listeners registered
with this object, and all listeners this object might have registered on
other objects.
- Specified by:
dispose
in interface IObservable
- Overrides:
dispose
in class AbstractObservable
getElementType
public Object getElementType()
- Specified by:
getElementType
in interface IObservableSet
- Returns:
- the element type or
null
if untyped
