Package org.hibernate.query.criteria

Interface JpaQueryStructure<T>

All Superinterfaces:

JpaCriteriaNode, JpaQueryPart<T>, Serializable

All Known Implementing Classes:

SqmQuerySpec

public interface JpaQueryStructure<T>
extends JpaQueryPart<T>

Models a SELECT query. Used as a delegate in implementing CriteriaQuery and Subquery.

See Also:

• JpaCriteriaQuery
• JpaSubQuery

API Note:

Internally (HQL and SQM) Hibernate supports ordering and limiting for both root- and sub- criteria even though JPA only defines support for them on a root.
