ojb.broker.cache
Class MetaObjectCacheImpl

java.lang.Object
  ojb.broker.cache.MetaObjectCacheImpl

All Implemented Interfaces:: ObjectCache

public class MetaObjectCacheImpl
extends java.lang.Object
implements ObjectCache

This cache makes it possible to have separate cache implementations for each class. When an object is cached / looked up the MetaObjectCacheImpl checks if a special ObjectCache has been set for this class. It recursively looks up the superclasses of the given object to look for a special cache. If no special cache is found it uses the ObjectCacheDefaultImpl to cache the object.
It is also possible to switch off caching for a specific class by setting the object cache to null.
