I need some solution for the code given below, In this code, I want variables. I want to know that which variables returns from GPInitializer.

       GPType typ = (GPType)(e.nextElement());
        // make vectors for the type.
        Vector nodes_v = new Vector();
        Vector terminals_v = new Vector();
        Vector nonterminals_v = new Vector();

        // add GPFuncInfos as appropriate to each vector
        Enumeration v = tmp.elements();
        while (v.hasMoreElements())
            GPFuncInfo i = (GPFuncInfo)(v.nextElement());
            if (typ.compatibleWith(i.node.constraints().returntype,typ))
                if (i.node.children.length == 0)
                else nonterminals_v.addElement(i);

Best Regards,
