private Status c()
    {
        Status status = null;
        Iterator iterator = a.iterator();
        do
        {
            while (!iterator.hasNext())
                if (status != null)
                    return status;
                else
                    return b;
            ImportLogEntry importlogentry = (ImportLogEntry)iterator.next();
            status = b.eval(importlogentry.getStatus());

        }
        return tmp==null ? status : tmp;
