Persisting Extended Collections

Hi,
Is it possible to persist the toPersistAttr attribute below as a collection, since it has no extra attributes to Set, just helper methods? What annotations (or xml) is required to do this? I couldn't find anything, so I suspect the answer is no. Figured it doesn't hurt to ask.

Using a @OneToMany attribute on the get method produces the following exception:

Code:

org.hibernate.AnnotationException: CollectionHelper collection not yet supported

Code:

public class CollectionHelper extends Set<B>
{
  public void helperMethod();
}

public class ToPersist
{
  public CollectionHelper toPersistAttr;
}

Thanks,
- Xavier

CustomCollectionType - there is an example in the h3 unit tests.

why is hibernate3 unit tests not enough for you ? (do a search in your hibernate directory and you will find it)

I'm afraid I don't see it.

I just checked out

http://anonsvn.jboss.org/repos/hibernat ... Hibernate3

and searched for

CustomCollectionType

and found nothing. Nor do I see anything in the test subfolder that looks like a test for the CustomCollectionType.

What is the difference between the two?

usercollectiontype is an interface while the other is a class

Yes I Understand that one is a interface and the other is a class, but the class does not implement the interface. Functionally what is the difference? Why do they both exist?
