hibernate restrictions and/or order

Question

small questions about Restrictions.or and Restrictions.and

If I do something like this:

...
criterion = criterionA;
criterion = Restrictions.and(criterion, criterionB);
criterion = Restrictions.or(criterion, criterionC);
criterion = Restrictions.and(criterion, criterionD);

Will this be treated as:

(A and B) or (C and D) (following mathematical conventions)

Or will it be treated in the order it the restrictions have been added:

(((A and B) or C) and D)

Please also add references if there are any...

Answer 1

It should be treated as the latter

(((A and B) or C) and D)

You could do

criterion = Restriction.or(Restrictions.and(criterionA, criterionB), Restrictions.and(criterionC, criterionD))

If you want the first solution
