how to get objects locked by a transaction?

[Jair da Silva Ferreira J�nior]

Hello,
    How can I safely get all objects locked by a transaction using ODMG or broker API?
    I need this because I want to remove all objects locked by a transaction from the 
cache. Something like this:

        .....
        Iterator lockedObjects=getLockedObjects(transaction);
        while(lockedObjects.hasNext()){
            broker.removeFromCache(lockedObjects.next());
        }
        .....
    
Thanks,
    Jair Jr
