public static interface PrintVisitor.PrintRulesI

This interface specifies the method needed to implement a special print rule. A special rule must implement the append method, which should call pv.append to add data to the output. For example

        pv.addSpecialRule(Operator.OP_LIST,new PrintVisitor.PrintRulesI()
        {
        public void append(Node node,PrintVisitor pv) throws ParseException
                {
                        pv.append("[");
                        for(int i=0;i0) pv.append(",");
                                node.jjtGetChild(i).jjtAccept(pv, null);
                        }
                        pv.append("]");
                }});
