The use of 'CaseBuilder()' example

CaseBuilder.java

// String compare, Result Long
// query().from(cat).list(cat.name.when("Bob").then(1).otherwise(2));
// java.lang.ClassCastException: org.hibernate.hql.ast.tree.ParameterNode cannot be cast to org.hibernate.hql.ast.tree.SelectExpression
// https://github.com/querydsl/querydsl/issues/185
query().from(cat).list(cat.name.when("Bob").then(Expressions.numberTemplate(Long, "1")).otherwise(Expressions.numberTemplate(Long, "2")));

// String hour compare, Result String
StringExpression amPm = new CaseBuilder().when(o.hour.lt("1200")).then("AM").otherwise("PM");
