Class Summary

Class	Description
BackgroundCleaner	A background cleaner that ConcurrentCache can use to clean Cacheables asynchronously in a background instead of synchronously in the user threads.
CachedItem	A generic class to represent the cache related infomation of a cached object (Cacheable).
CacheEntry	Class representing an entry in the cache.
CacheStat
Clock	A cache manager that uses a HashMap and an ArrayList.
ClockFactory	Multithreading considerations: no need to be MT-safe, caller (module control) provides synchronization.
ClockPolicy	Implementation of a replacement policy which uses the clock algorithm.
ConcurrentCache	A cache manager based on the utilities found in the java.util.concurrent package.
ConcurrentCacheFactory	Factory class which creates cache manager instances based on the ConcurrentCache implementation.
