Class AutoCache

java.lang.Object
  org.jboss.dashboard.database.cache.custom.AutoCache

All Implemented Interfaces:

ObjectCache, StatisticsObjectCache

public class AutoCache
extends Object
implements StatisticsObjectCache

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.
