Examples of org.hibernate.persister.entity.Lockable

org.hibernate.persister.entity.Lockable
Contract for things that can be locked via a {@link org.hibernate.dialect.lock.LockingStrategy}.
Currently only the root table gets locked, except for the case of HQL and Criteria queries against dialects which do not support either (1) FOR UPDATE OF or (2) support hint locking (in which case *all* queried tables would be locked). @author Steve Ebersole @since 3.2
