@Deprecated(since="7",
            forRemoval=true)
public class LockOptions
extends Object
implements Serializable

Deprecated, for removal: This API element is subject to removal in a future version.

Since JPA 3.2 and Hibernate 7, a LockMode, Timeout, or PessimisticLockScope may be passed directly as an option to find(), refresh(), or lock(). Therefore, this class is obsolete as an API and will be moved to an SPI package.

For HQL/JPQL queries, locking should be controlled via operations of the SelectionQuery interface:

• A timeout may be set via CommonQueryContract.setTimeout(Timeout)
• The PessimisticLockScope may be set using SelectionQuery.setLockScope(PessimisticLockScope)
• Alias-specific lock modes may be specified using SelectionQuery.setLockMode(String, LockMode)
• Use of follow-on locking may be enabled via SelectionQuery.setFollowOnLocking(boolean)

The interface Timeouts provides several operations to simplify migration.

Contains a set of options describing how a row of a database table mapped by an entity should be locked. For Session.lock(Object, LockOptions), Session.get(Class, Object, LockOptions), or Session.refresh(Object, LockOptions), the relevant options are:

• the lock mode,
• the pessimistic lock timeout, and
• the lock scope, that is, whether the lock extends to rows of owned collections.

Timeout and lock scope are ignored if the specified LockMode represents a flavor of optimistic locking.

In HQL and criteria queries, lock modes can be defined in an even more granular fashion, with the option to specify a lock mode that applies only to a certain query alias.

Finally, the use of follow-on locking may be force enabled or disabled, overriding the default behavior of the SQL dialect by passing a non-null argument to setFollowOnLocking(Boolean).
