org.datanucleus.store.rdbms.request.FetchRequest
Class to retrieve the fields of an object of a specified class from the datastore. If some of those fields are themselves persistent objects then this can optionally retrieve fields of those objects in the same fetch.
Any surrogate version stored in this table will be fetched *if* the object being updated doesn't already have a value for it. If the caller wants the surrogate version to be updated then they should nullify the "transactional" version before calling.

        RequestIdentifier reqID = new RequestIdentifier(table, mmds, RequestType.FETCH, 
            cmd.getFullClassName());
        Request req = requestsByID.get(reqID);
        if (req == null)
        {
            req = new FetchRequest(table, mmds, cmd, clr);
            requestsByID.put(reqID, req);
        }
        return req;
    }
