Interface PrintVisitor.PrintRulesI

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

PrintVisitor.StdElePrintRule, PrintVisitor.StdListPrintRule

Enclosing class:

PrintVisitor

public static interface PrintVisitor.PrintRulesI
extends java.io.Serializable

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 a string to the output, call pv.printNoBrackets(node) to print a node with no bracket call pv.printBrackets(node) to print a node surrounded by round brackets.

For example

        pv.addSpecialRule(Operator op,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("]");
                }});
