程序包 org.hibernate.query.criteria.internal.expression

类 NullifExpression<T>

java.lang.Object

org.hibernate.query.criteria.internal.AbstractNode

org.hibernate.query.criteria.internal.expression.AbstractTupleElement<X>

org.hibernate.query.criteria.internal.expression.SelectionImpl<T>

org.hibernate.query.criteria.internal.expression.ExpressionImpl<T>

org.hibernate.query.criteria.internal.expression.NullifExpression<T>

所有已实现的接口:

Serializable, javax.persistence.criteria.Expression<T>, javax.persistence.criteria.Selection<T>, javax.persistence.TupleElement<T>, ExpressionImplementor<T>, ParameterContainer, Renderable, SelectionImplementor<T>, TupleElementImplementor<T>

public class NullifExpression<T>
extends ExpressionImpl<T>
implements Serializable

Models an ANSI SQL NULLIF expression. NULLIF is a specialized CASE statement.
