Interface CacheManagerEventListener

public interface CacheManagerEventListener

Allows implementers to register callback methods that will be executed when a CacheManager event occurs. The events include:

1. adding a Cache
2. removing a Cache

Callbacks to these methods are synchronous and unsynchronized. It is the responsibility of the implementer to safely handle the potential performance and thread safety issues depending on what their listener is doing.

void	notifyCacheAdded(java.lang.String cacheName) Called immediately after a cache has been added and activated.
void	notifyCacheRemoved(java.lang.String cacheName) Called immediately after a cache has been disposed and removed.

Method Detail

notifyCacheAdded

public void notifyCacheAdded(java.lang.String cacheName)

Called immediately after a cache has been added and activated.

Note that the CacheManager calls this method from a synchronized method. Any attempt to call a synchronized method on CacheManager from this method will cause a deadlock.

Note that activation will also cause a CacheEventListener status change notification from Status.STATUS_UNINITIALISED to Status.STATUS_ALIVE. Care should be taken on processing that notification because:

• the cache will not yet be accessible from the CacheManager.
• the addCaches methods whih cause this notification are synchronized on the CacheManager. An attempt to call CacheManager.getCache(String) will cause a deadlock.

The calling method will block until this method returns.

Parameters:

cacheName - the name of the Cache the operation relates to

notifyCacheRemoved

public void notifyCacheRemoved(java.lang.String cacheName)

Called immediately after a cache has been disposed and removed. The calling method will block until this method returns.

Note that the CacheManager calls this method from a synchronized method. Any attempt to call a synchronized method on CacheManager from this method will cause a deadlock.

Note that a CacheEventListener status changed will also be triggered. Any attempt from that notification to access CacheManager will also result in a deadlock.

Parameters:

cacheName - the name of the Cache the operation relates to
