      • 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:
        true if this observable's state is stale and will change soon.
      • getterCalled

        protected void getterCalled()
      • firstListenerAdded

        protected void firstListenerAdded()
      • lastListenerRemoved

        protected void lastListenerRemoved()
      • handleStaleEvent

        protected void handleStaleEvent​(StaleEvent event)
        Called whenever a StaleEvent is received from the decorated observable. By default, this method fires the stale event again, with the decorating observable as the event source. Subclasses may override to provide different behavior.
        Parameters:
        event - the stale event received from the decorated observable
      • hashCode

        public int hashCode()
        Overrides:

      • 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
