Class ClassNamePatternClusterSelector

  org.axonframework.eventhandling.AbstractClusterSelector
      org.axonframework.eventhandling.ClassNamePatternClusterSelector

All Implemented Interfaces:

ClusterSelector

public class ClassNamePatternClusterSelector
extends AbstractClusterSelector

ClusterSelector implementation that chooses a Cluster based on whether the Listener's Class Name matches a given Pattern.

The given pattern must match the entire class name, not just part of it.

Note that the name of the class used is the name of the class implementing the EventListener interface. If a listener implements the EventListenerProxy interface, the value of the EventListenerProxy.getTargetType() is used. Annotated Event Listeners will always have the actual annotated class name used.

cluster - The cluster to choose when the pattern matches

Method Detail

doSelectCluster

public Cluster doSelectCluster(EventListener eventListener,
                               Class listenerType)

Description copied from class: AbstractClusterSelector

Select a cluster for the given eventListener, which has the actual class listenerType. Note that the given listenerType does not have to be assignable to EventListener, as it is possible that the eventListener acts as a proxy to an instance of listenerType.

Specified by:

doSelectCluster in class AbstractClusterSelector

Parameters:

eventListener - The listener instance handling the events, possibly a proxy

listenerType - The actual type of the Event Listener

Returns:

the cluster to assign the Event Listener to
