Map to non managed entity with criteria-api

Question

In JPA1 you could map a result to a non-managed entity by something like this:

Query query = entityManager.createQuery("SELECT NEW com.test.TestInfo(e.name, e.city) from Example e");

In JPA2 you could do it like this :

Query query = entityManager.createQuery(“SELECT e.name, e.city from Example e”,TestInfo.Class);

How would I do that with the criteria-api? I simply don't know the buzzwords to google for.

Any hints?

That can be done via CriteriaBuilder.construct. First argument is class of result, following arguments are Selections.
