Enum Class OptimisticLockStyle

java.lang.Object

java.lang.Enum<OptimisticLockStyle>

org.hibernate.engine.OptimisticLockStyle

All Implemented Interfaces:

Serializable, Comparable<OptimisticLockStyle>, Constable

public enum OptimisticLockStyle
extends Enum<OptimisticLockStyle>

Describes how an entity should be optimistically locked.

API Note:

This enumeration is mainly for internal use, since it is isomorphic to OptimisticLockType. In the future, it would be nice to replace them both with a new org.hibernate.OptimisticLockCheck enum.
