Search proxies without materialization

[Piet Molenaar]

Hi,
First of all, ojb is great and I find great support on this list.
Unfortunately I did not find a solution to the following problem.
At the moment I'm implementing a persistent datalayer for an application 
that has to perform queries over large sets of data.
I only want to search for id's so I use dynamic proxies, but I don't want 
to materialize each proxy to query its details.
Now I implemented something like:

   for (Iterator iter = 
myCreatedPersistenceBroker.getIteratorByQuery(someQueryReturningLargeSet);
         iter.hasNext(); )
    {
      java.lang.reflect.Proxy item = (java.lang.reflect.Proxy) iter.next();
      IndirectionHandler handler = (IndirectionHandler) 
item.getInvocationHandler(item);
      Object[] values = handler.getIdentity().getPrimaryKeyValues();
      if (values[0].equals(theIdSearchedFor) )
      {
        TargetInterface target = (TargetInterface) item;
	
      }
    }

This worked and was in a first test about 5 times faster than querying all 
materialized proxies but it seems so complicated to me.
Is there a proper way to achieve this using ojb-pb api or am I 
misunderstanding something completely?

thanks a lot in advance,
Piet
