  org.gcube.common.core.utils.handlers.events.Monitor

All Implemented Interfaces:

GCUBEConsumer<Topic,Object>

public abstract class Monitor
extends Object
implements GCUBEConsumer<Topic,Object>

Abstract specialisation of GCUBEConsumer for consumers of Events.

Monitor implements GCUBEConsumer.onEvent(GCUBEEvent...) to dispatch LifetimeEvents to event-specific callbacks and any other Event to a catch-all callback (cf. onAnyEvent(Event).
Subclasses may also extend onEvent(GCUBEEvent...) to extend the callback pattern to other types of Event.
