      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      java.io.Serializable[] getDisassembledState()
      Get the underlying disassembled state todo : this was added to support initializing an entity's EntityEntry snapshot during reattach; this should be refactored to instead expose a method to assemble an EntityEntry based on this state for return.
      java.lang.Object getReference()
      Provides access to the stored reference.
      java.lang.String getSubclass()
      Hibernate stores all entries pertaining to a given entity hierarchy in a single region.
      EntityPersister getSubclassPersister()  
      java.lang.Object getVersion()
      Retrieves the version (optimistic locking) associated with this cache entry.
      boolean isReferenceEntry()
      Does this entry represent a direct entity reference (rather than disassembled state)?
