Interface ObservableObserver<O extends Observable<?>>

  • Type Parameters:
    O - The type of the observable being observed.

    public interface ObservableObserver<O extends Observable<?>>
    An ObservableObserver is an observer, observing an observable. In this case, it is a listener interface listening for the most basic functionality an observable must provide in order to be an observable: Subscribing and unsubscribing of listeners (observers). The implementing observer, when registered to an according observable, gets its onSubscribe(SubscribeEvent) or onUnsubscribe(UnsubscribeEvent) methods invoked when the according functionality is invoked upon the observable in question.
