Inheritance and Customization

[Maksimenko Alexander <ma...@bird.cris.net>]

Hi!
In the article "Advanced Object Relational Mapping techniques ****" in 
the section "Mapping All Classes on the Same Table" is written that it's 
possible to customize field which determines concrete type of extent 
(ojbConcreteClass by default).
I want to customize both the name and type of the field.
But the QueryFactory class add criterias which discriminate concrete 
classes if and only if search class has field with name "ojbConcreteClass".
So if I change the field's name I can't  use abstract class as reference 
in other objects.
The situation is same with fields type. QueryFactory class adds concrete 
class names in InCriteria and there are not query-customizer in 
class-descriptor level to change the names to some integer values.
So in fact I can't customize the field if I want use abstract classes as 
references in other objects. Am I right?

Sorry for stupid question.
Of cause all OK  - if you specify your own RowReader implementation you 
can tell to OJB which class it have instantiate
