                       java.lang.Object object2,
                       org.eclipse.persistence.internal.sessions.AbstractSession session)

  INTERNAL: Compare the attributes belonging to this mapping for the objects.

• mergeChangesIntoObject

                            org.eclipse.persistence.internal.sessions.ChangeRecord changeRecord,

• mergeIntoObject

  public void mergeIntoObject(java.lang.Object target,
                     boolean isTargetUnInitialized,
                     java.lang.Object source,
