LockingStrategy

org.hibernate.dialect.lock.LockingStrategy
Known Indirect Subclasses

Class Overview

A strategy abstraction for how locks are obtained in the underlying database.

All locking provided implementations assume the underlying database supports (and that the connection is in) at least read-committed transaction isolation. The most glaring exclusion to this is HSQLDB which only offers support for READ_UNCOMMITTED isolation.
