Interface PrintVisitor.PrintRulesI

Enclosing class:
  PrintVisitor

    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("]");
                    }});
