org.eclipse.persistence.descriptors.ChangedFieldsLockingPolicy

Purpose: An implementation of the OptimisticLockingPolicy interface. This policy compares only the changed fields in the WHERE clause when doing an update. If any field has been changed, an optimistic locking exception will be thrown. A delete will only compare the primary key.
NOTE: This policy can only be used inside a unit of work. @since TopLink 2.1 @author Peter Krogh
