Restrictions for class type of associated object

azachar · **Joined:** Sun May 28, 2006 1:09 pm **Posts:** 2

Suppose example:

B - an abstract class
B1 - a (concrete) subclass of class B
B2 - a subclass of class B

A - class that is asociated with B like this A.getB()

Criteria rootCriteria = session.createCriteria(A.class);
Criteria asociatedCriteria = rootCriteria.createCriteria("B");

Is it possible to query like this?
asociatedCriteria.add(Restrictions.eq("class", B1.class));

How can I reach this polymorphism restriction on associations?

Thanks for your answers, or future soon implementation.
