Interface Summary

Interface	Description
Cluster	A cluster represents a group of Event Listeners that are treated as a single group by the ClusteringEventBus.
ClusterMetaData	Allows arbitrary information to be attached to a cluster.
ClusterSelector	The ClusterSelector defines the mechanism that assigns each of the subscribed listeners to a Cluster instance.
EventBus	Specification of the mechanism on which the Event Listeners can subscribe for events and event publishers can publish their events.
EventBusTerminal	Interface describing a mechanism that connects Event Bus clusters.
EventListener	Interface to be implemented by classes that can handle events.
EventListenerProxy	Specialist interface for implementations of an event listener that redirect actual processing to another instance.
EventProcessingMonitor	Interface describing a mechanism that listens for the results of events being processed.
EventProcessingMonitorSupport	Interface indicating that the implementing class is capable of notifying monitors when event processing completes.
OrderResolver	Interface describing a mechanism that provides the order for any given Event Listener.
SimpleEventBusStatisticsMXBean	Management interface the SimpleEventBus monitor.

Class Summary

Class	Description
AbstractCluster	Abstract Cluster implementation that keeps track of Cluster members (EventListeners).
AbstractClusterSelector	Abstract implementation of the ClusterSelector interface that detects proxies and passes the actual Class of the Event Listener implementation.
AnnotationClusterSelector	Cluster Selector implementation that selects a cluster if an Annotation is present on the Event Listener class.
AutowiringClusterSelector	Cluster selector implementation that uses a Spring Application Context to find all selector beans available.
ClassNamePatternClusterSelector	ClusterSelector implementation that chooses a Cluster based on whether the Listener's Class Name matches a given Pattern.
ClassNamePrefixClusterSelector	ClusterSelector implementation that chooses a Cluster based on a mapping of the Listener's Class Name.
ClusteringEventBus	EventBus implementation that supports clustering of Event Listeners.
CompositeClusterSelector	ClusterSelector implementation that delegates the selection to a list of other ClusterSelectors.
DefaultClusterMetaData	Default implementation of ClusterMetaData.
DefaultClusterSelector	ClusterSelector implementation that always selects the same cluster.
EventListenerOrderComparator	Comparator implementation that uses an OrderResolver instance to define the expected order of two candidates.
EventProcessingMonitorCollection	Implementation of the EventProcessingMonitor that delegates to all registered EventProcessingMonitor instances.
EventTemplate	Template class that dispatches Events to an EventBus, taking active UnitOfWork into account.
MultiplexingEventProcessingMonitor	Implementation of the EventProcessingMonitor that receives multiple invocations of downstream monitors and translates that to a single invocation to a target monitor.
SimpleCluster	A simple Cluster implementation that invokes each of the members of a cluster when an Event is published.
SimpleClusterFactoryBean	FactoryBean that creates an instance of a SimpleCluster, allowing easier access to the MetaData.
SimpleEventBus	Implementation of the EventBus that directly forwards all published events (in the callers' thread) to all subscribed listeners.
SimpleEventBusStatistics	Statistics object to store information about the internal of the SimpleEventBus.
SpringAnnotationOrderResolver	OrderResolver implementation that checks for @Order annotations on the type level.

Exception Summary

Exception	Description
EventListenerSubscriptionFailedException	Exception indicating that the subscription of an Event Listener has not succeeded.
