Class ConfluenceDirectoryEventListener

java.lang.Object
  com.atlassian.confluence.user.crowd.ConfluenceDirectoryEventListener

All Implemented Interfaces:

EventListener, org.springframework.context.ApplicationListener

public final class ConfluenceDirectoryEventListener
extends Object
implements org.springframework.context.ApplicationListener

Propagates DirectoryUpdatedEvent and DirectoryDeletedEvent to other nodes in a cluster to trigger the relevant updates to caches and directory monitors on each node.

When this listener receives one of those events, it is wrapped and republished via ClusterManager.publishEvent(ConfluenceEvent). The same listener on the other nodes receives the cluster wrapper event, unwraps the original event and republishes it.

Republished events have a null source to distinguish them from original events occurring on the the local node.

Nested Class Summary

static class	ConfluenceDirectoryEventListener.ClusterDirectoryDeletedEvent
protected static class	ConfluenceDirectoryEventListener.ClusterDirectoryEvent Crowd's event classes are not Serializable, so we need to extract the event class and directory, then reconstruct the event on the other nodes.
static class	ConfluenceDirectoryEventListener.ClusterDirectoryUpdatedEvent

Constructor Summary

ConfluenceDirectoryEventListener(ClusterManager clusterManager, com.atlassian.event.api.EventPublisher eventPublisher)

Method Summary

void	handleEventOnThisNode(com.atlassian.crowd.event.directory.DirectoryDeletedEvent directoryDeletedEvent) Handles directory modification events on the current node, republishing this to other nodes in the cluster once the current transaction is complete.
void	handleEventOnThisNode(com.atlassian.crowd.event.directory.DirectoryUpdatedEvent directoryUpdatedEvent) Handles directory modification events on the current node, republishing this to other nodes in the cluster once the current transaction is complete.
void	onApplicationEvent(org.springframework.context.ApplicationEvent event) Handles cluster events from other nodes.

Constructor Detail

ConfluenceDirectoryEventListener

public ConfluenceDirectoryEventListener(ClusterManager clusterManager,
                                        com.atlassian.event.api.EventPublisher eventPublisher)

Method Detail

handleEventOnThisNode

@EventListener
public void handleEventOnThisNode(com.atlassian.crowd.event.directory.DirectoryDeletedEvent directoryDeletedEvent)

Handles directory modification events on the current node, republishing this to other nodes in the cluster once the current transaction is complete.

handleEventOnThisNode

@EventListener
public void handleEventOnThisNode(com.atlassian.crowd.event.directory.DirectoryUpdatedEvent directoryUpdatedEvent)

Handles directory modification events on the current node, republishing this to other nodes in the cluster once the current transaction is complete.

onApplicationEvent

public void onApplicationEvent(org.springframework.context.ApplicationEvent event)

Handles cluster events from other nodes.

Assumes that the call to ClusterManager.publishEvent(ConfluenceEvent) above actually ends up invoking the legacy EventManager on all nodes to publish a Spring ApplicationEvent with the relevant information.
