Package org.datanucleus.api.jpa.criteria

Class SubqueryImpl<T>

  • All Implemented Interfaces:
    Serializable, javax.persistence.criteria.AbstractQuery<T>, javax.persistence.criteria.CommonAbstractCriteria, javax.persistence.criteria.Expression<T>, javax.persistence.criteria.Selection<T>, javax.persistence.criteria.Subquery<T>, javax.persistence.TupleElement<T>
    public class SubqueryImpl<T>
extends ExpressionImpl<T>
implements javax.persistence.criteria.Subquery<T>
    Implementation of JPA2 Criteria "Subquery". A subquery in DataNucleus is represented as a variable (as it is in JDOQL), consequently this expression is backed by a VariableExpression.
