org.hibernate.util.SoftLimitMRUCache

Cache following a "Most Recently Used" (MRY) algorithm for maintaining a bounded in-memory size; the "Least Recently Used" (LRU) entry is the first available for removal from the cache.

This implementation uses a "soft limit" to the in-memory size of the cache, meaning that all cache entries are kept within a completely {@link java.lang.ref.SoftReference}-based map with the most recently utilized entries additionally kept in a hard-reference manner to prevent those cache entries soft references from becoming enqueued by the garbage collector. Thus the actual size of this cache impl can actually grow beyond the stated max size bound as long as GC is not actively seeking soft references for enqueuement. @author Steve Ebersole
