Interface EventListenerInterface

All Superinterfaces:
EventListener, Serializable
All Known Subinterfaces:
RemoteEventListenerInterface
All Known Implementing Classes:
EventProducingCollection, EventProducingList, EventProducingSet, RemoteEventListener
public interface EventListenerInterface
extends EventListener, Serializable
The EventListenerInterface creates a callback method for publishers to inform their clients. The EventListener and EventProducer together form a combination of the Publish-Subscribe design pattern and the Observer design pattern using the notify(event) method. See https://en.wikipedia.org/wiki/Publish-subscribe_pattern, https://en.wikipedia.org/wiki/Observer_pattern, and https://howtodoinjava.com/design-patterns/behavioral/observer-design-pattern/.
