Class LoadingCache<K,V>

java.lang.Object

net.sf.ehcache.constructs.EhcacheDecoratorAdapter

net.sf.ehcache.constructs.blocking.BlockingCache

com.atlassian.cache.ehcache.LoadingCache<K,V>

Type Parameters:

K - the cache's key type

V - the cache's value type

All Implemented Interfaces:

Cloneable, net.sf.ehcache.Ehcache, net.sf.ehcache.terracotta.InternalEhcache

public class LoadingCache<K,V>
extends net.sf.ehcache.constructs.blocking.BlockingCache

A rewrite of SelfPopulatingCache with stronger concurrency guarantees. Unfortunately, since the locks are local and cache replication happens at the Ehcache layer, bypassing these locks, this is still not good enough for clusters. It is, however, an improvement.
