TODO:

Support clearing updated objects for hot cache between transactions. Add metadata boolean that indicates whether the object was modified since the cache was last cleared regardless of whether the object has since been installed on the persistence layer and marked as clean. The purpose of this is to support clearing of modified objects from the object cache when a transaction is aborted. Such objects must be cleared if they have been modified since they were installed in the cache regardless of whether they are currently dirty or not. Supporting this feature will probably require a hard reference Set containing the object identifier of each object that was marked as dirty in the cache since the cache was last cleared.

Method Summary

boolean	isDirty() Return true iff the object associated with this entry is dirty.
