      • setObservationContext

        public void setObservationContext​(IObservationContext context)
        Description copied from interface: IObservable
        Before observation is started on the observable, an observation context is injected by the observer registry. This context can be used to notify listeners.
        Specified by:
        setObservationContext in interface IObservable
      • startObservation

        public void startObservation()
        Description copied from interface: IObservable
        When the first IObserver of this observable is registered with the observer registry, observation is started. Implementations must notify observers until observation is stopped.

        An implementation should register listeners with external data sources, when appropriate. It is possible for an observable to register as an observer for another observable.

        Specified by:
        startObservation in interface IObservable
      • stopObservation

        public void stopObservation()
        Description copied from interface: IObservable
        When the last IObserver unregisters, observation is stopped. Any listeners or observers registered by the observable must be unregistered by the implementation.
        Specified by:
        stopObservation in interface IObservable
      • detach

        public void detach()
        Specified by:
        detach in interface org.apache.wicket.model.IDetachable
