Class CacheEntryListener

java.lang.Object

org.appng.core.service.cache.CacheEntryListener

All Implemented Interfaces:

Serializable, EventListener, javax.cache.event.CacheEntryCreatedListener<String,CachedResponse>, javax.cache.event.CacheEntryExpiredListener<String,CachedResponse>, javax.cache.event.CacheEntryListener<String,CachedResponse>, javax.cache.event.CacheEntryRemovedListener<String,CachedResponse>

public class CacheEntryListener
extends Object
implements javax.cache.event.CacheEntryCreatedListener<String,CachedResponse>, javax.cache.event.CacheEntryRemovedListener<String,CachedResponse>, javax.cache.event.CacheEntryExpiredListener<String,CachedResponse>, Serializable

A CacheEntryListener that keeps track of the cache's keys. Used in CacheService to make it possible to expire cache elements by their key without having to iterate over all the values (which is slow for large caches).
