How to do JOIN ON query using Criteria API

Since version 2.1 JPA supports join on. I found few examples how to use join on in JPQL but none for Criteria API, and here is my question:

Is JOIN ON is implemented in Criteria APi? And if yes, Can anyone provide example?

Try something like this

CriteriaQuery<Person> crit = cb.createQuery(Person.class);
Root<Person> candidateRoot = crit.from(Person.class);
Join<Person, Address> addrJoin = candidateRoot.join(Person_.address, JoinType.INNER);
addrJoin.on({some predicate});

filling "{some predicate}" with whatever ON clause you want to impose.
