Class CacheEntryEventListenerImpl

java.lang.Object
  com.opensymphony.oscache.extra.CacheEntryEventListenerImpl

All Implemented Interfaces:

CacheEntryEventListener, CacheEventListener, EventListener

public class CacheEntryEventListenerImpl
extends Object
implements CacheEntryEventListener

Implementation of a CacheEntryEventListener. It use the events to count the operations performed on the cache.

We are not using any synchronized so that this does not become a bottleneck. The consequence is that on retrieving values, the operations that are currently being done won't be counted.
