AbstractNotifier

abstract class AbstractNotifier<E> : Notifier<E> , Listenable<E> (source)

Abstract implementation of Notifier that also implements Listenable.

This class provides a complete implementation of the observer pattern, combining both the ability to register/unregister listeners (from Listenable) and the ability to notify them of events (from Notifier).

The implementation maintains a set of listeners and ensures safe event delivery even if individual listeners throw exceptions.
