Class AutoCache

java.lang.Object

net.sf.swarmcache.AutoCache

All Implemented Interfaces:

ObjectCache

public class AutoCache
extends java.lang.Object
implements ObjectCache

This cache implementation uses soft references so that cached objects are automatically garbage collected when needed. Note that this maximizes the cache size at the expense of making no guarantees as to the cache-clearing algorithm used. So, it makes for good memory use at the possible expense of cache hit frequency.
