Interface LockingStrategy
- HSQLDialect.ReadUncommittedLockingStrategy, SelectLockingStrategy, UpdateLockingStrategy
public interface LockingStrategy
A strategy abstraction for how locks are obtained in the underlying database.
All locking provided implemenations 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.
void | lock(Serializable id, Object version, Object object, SessionImplementor session) - Acquire an appropriate type of lock on the underlying data that will
endure until the end of the current transaction.
