Class PermanentObjectCacheImpl

  ojb.broker.cache.PermanentObjectCacheImpl

All Implemented Interfaces:: ObjectCache

public class PermanentObjectCacheImpl
extends java.lang.Object
implements ObjectCache

This is an implementation of the ObjectCache interface that caches all objects in memory regardless of memory consumption.
It is not intended to be used as the main ObjectCache but only to be used in conjunction with the MultipleObjectCacheImpl for special object classes. It should only be used for objects which are few in number and not too big in size but expensive to re-create from the DB.
