org.hibernate.persister.entity
Interface Lockable

All Superinterfaces:: EntityPersister, OptimisticCacheSource

All Known Implementing Classes:: AbstractEntityPersister

public interface Lockable
extends EntityPersister

Contract for things that can be locked via a 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).

String[] getRootTableIdentifierColumnNames()
          Get the names of columns on the root table used to persist the identifier.

String getRootTableName()
          Locks are always applied to the "root table".

String getVersionColumnName()
          For versioned entities, get the name of the column (again, expected on the root table) used to store the version values.
