org.eclipse.persistence.descriptors.SelectedFieldsLockingPolicy

Purpose: An implementation of the OptimisticLockingPolicy interface. This policy compares selected fields in the WHERE clause when doing an update or a delete. If any field has been changed, an optimistic locking exception will be thrown. Note that the fields specified must be mapped and not be primary keys.
NOTE: This policy can only be used inside a unit of work. @since TopLink 2.5
