public class StaleEvent extends ObservableEvent
IObservableobject is about to change. Note that this event is only fired when an observable becomes stale, not when it becomes unstale; an observable that becomes unstale should always fire a change event. Staleness can be used (for example) to notify listeners when an observable has started a background thread for updating its state. Clients can safely ignore staleness.
