Lets say I have 3 very complex Java classes (ClassA, ClassB, ClassC) with some inheritance:
ClassC extends ClassA
ClassB extends ClassA

I want to obtain the identifier of a set of objects and the class of this objects:

for(ClassA element: getSession(false).createQuery("from ClassA where ...").list() ) {
doSomeProcessWith( element.getClass(), element.getId() )
}

Because I have really complex objects, this HQL query causes a heavy database query (complete ClassA objects and inheritance solving causes complex queries).

Then I try this alternative query (causing a really simple sql query)

for(Object[] element: getSession(false).createQuery("select class, id from ClassA where ...").list() {
doSomeProcessWith( element[0], element[1] )
}

The problem here is Hibernate solves "class" as an integer value (the class discriminator in a polymorfic query)

¿Is there any way to obtain the Java Class as a result in HQL?
¿Is there any way to traslate the HQL polymorfic discriminator in a Java Class object?

Thanks a lot
