Hibernate Criteria Restrictions AND / OR combination

Question

How would I achieve this using Hibernate Restrictions?

(((A=\'X\') and (B in(\'X\',Y))) or ((A=\'Y\') and (B=\'Z\')))

Answer 1

think works

Criteria criteria = getSession().createCriteria(clazz); 
Criterion rest1= Restrictions.and(Restrictions.eq(A, "X"), 
           Restrictions.in("B", Arrays.asList("X",Y)));
Criterion rest2= Restrictions.and(Restrictions.eq(A, "Y"), 
           Restrictions.eq(B, "Z"));
criteria.add(Restrictions.or(rest1, rest2));
