Class AbstractQueryImpl<X>

java.lang.Object

org.hibernate.ejb.AbstractQueryImpl<X>

All Implemented Interfaces:

javax.persistence.Query, javax.persistence.TypedQuery<X>

Direct Known Subclasses:

QueryImpl

public abstract class AbstractQueryImpl<X>
extends Object
implements javax.persistence.TypedQuery<X>

Intended as a base class providing convenience in implementing both Query and TypedQuery.

IMPL NOTE : This issue, and the reason for this distinction, is that criteria and hl.sql queries share no commonality currently in Hibernate internals.
