Package com.querydsl.core.types.dsl

Class CaseForEqBuilder<D>

java.lang.Object

com.querydsl.core.types.dsl.CaseForEqBuilder<D>

Type Parameters:

D -

public final class CaseForEqBuilder<D>
extends Object

CaseForEqBuilder enables the construction of typesafe case-when-then-else constructs for equals-operations : e.g.

 QCustomer c = QCustomer.customer;
 Expression<Integer> cases = c.annualSpending
     .when(1000l).then(1)
     .when(2000l).then(2)
     .when(5000l).then(3)
     .otherwise(4);
