类 SimpleCaseExpression<C,R>

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<R>

org.hibernate.query.criteria.internal.expression.SimpleCaseExpression<C,R>

所有已实现的接口:

Serializable, javax.persistence.criteria.CriteriaBuilder.SimpleCase<C,R>, javax.persistence.criteria.Expression<R>, javax.persistence.criteria.Selection<R>, javax.persistence.TupleElement<R>, ExpressionImplementor<R>, ParameterContainer, Renderable, SelectionImplementor<R>, TupleElementImplementor<R>

public class SimpleCaseExpression<C,R>
extends ExpressionImpl<R>
implements javax.persistence.criteria.CriteriaBuilder.SimpleCase<C,R>, Serializable

Models what ANSI SQL terms a simple case statement. This is a CASE expression in the form

 CASE [expression]
     WHEN [firstCondition] THEN [firstResult]
     WHEN [secondCondition] THEN [secondResult]
     ELSE [defaultResult]
 END
