LockingStrategy

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.
