Models basic query structure. Used as a delegate in implementing both javax.persistence.criteria.CriteriaQuery and javax.persistence.criteria.Subquery.

Note the ORDER BY specs are neglected here. That's because it is not valid for a subquery to define an ORDER BY clause. So we just handle them on the root query directly...
