Interface ProxySubscriber

All Known Implementing Classes:

AbstractProxySubscriber, BaseProxySubscriber, ProxyTopicPatternSubscriber, ProxyTopicSubscriber

public interface ProxySubscriber

An interface that can be implemented when proxies are used for subscription, not needed in normal usage. When an unsubscribe method is called on an EventService, the EventService is required to check if any of subscribed objects are ProxySubscribers and if the object to be unsubscribed is the ProxySubscriber's proxiedSubscriber. If so, the EventService proxy is unsubscribed and the ProxySubscriber's proxyUnsubscribed() method is called to allow the proxy to perform any cleanup if necessary. ProxySubscribers should set their references to their proxied objects to null for strong subscriptions to allow garbage collection.
