Expression<R>, Selection<R>, TupleElement<R>
Enclosing interface:
CriteriaBuilder

public static interface CriteriaBuilder.SimpleCase<C,R>
extends Expression<R>

Interface used to build simple case expressions. Case conditions are evaluated in the order in which they are specified.


Method Summary
 Expression<C> getExpression()
          Return the expression to be tested against the conditions.
 Expression<R> otherwise(Expression<? extends R> result)
          Add an "else" clause to the case expression.
 Expression<R> otherwise(R result)
          Add an "else" clause to the case expression.
 CriteriaBuilder.SimpleCase<C,R> when(C condition, Expression<? extends R> result)
          Add a when/then clause to the case expression.
 CriteriaBuilder.SimpleCase<C,R> when(C condition, R result)
          Add a when/then clause to the case expression.
