Class QueryStructure<T>

java.lang.Object
  org.hibernate.ejb.criteria.QueryStructure<T>

All Implemented Interfaces:

Serializable

public class QueryStructure<T>
extends Object
implements Serializable

Models basic query structure. Used as a delegate in implementing both CriteriaQuery and 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...
