public class SearchedCaseExpression<R>
extends ExpressionImpl<R>
implements javax.persistence.criteria.CriteriaBuilder.Case<R>, java.io.Serializable

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

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