    • setObservationContext

      public void setObservationContext(IObservationContext<? extends IObservable> 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
