Convert criteria to detached criteria

Question

This question is titled similar to this one, but it's no duplicate as the other OP actually wanted something else (anyway, there's no answer to my question there). What I want is to recycle my already constructed Criteria in Subqueries.exists(DetachedCriteria).

I know that Criteria is basically DetachedCriteria with an attached Session, so I'd expect something like Criteria#toDetached() or a factory method on the other side, but I can't find anything.

Answer 1

As per OP , it helped him to solve his problem.

One of the way could be the one given in NHibernate: Convert an ICriteria to a DetachedCriteria Thats for Nhibernate, but same can done in Hibernate Also.

Answer 2

Trivially rewritten in Java:

public class MyDetachedCriteria extends DetachedCriteria {
    public OcDetachedCriteria(Criteria criteria) {
        super((CriteriaImpl) criteria, criteria);
        ((CriteriaImpl) criteria).setSession(null);
    }
}
