public Gen()

Method Detail

format

protected static String format(String key,
                               Object... args)

format a string from the resource file.

Parameters:

args - can be null if none.

prolog

public static void prolog(PrintWriter out,
                          Parser parser)

output prolog.

main

public static void main(PrintWriter out,
                        String parser,
                        boolean addNull,
                        String className)

output main program for compiler.

jlex

public static void jlex(PrintWriter out,
                        Parser parser)
                 throws IOException

generate JLex-based scanner. Requires patched version of JLex.

Throws:

IOException

jlexSource

public static void jlexSource(PrintWriter out,
                              Parser parser)

generate source of JLex-based scanner.

actions

public static void actions(PrintWriter out,
                           Parser parser)

generate actions interface.

factory

public static void factory(PrintWriter out,
                           Parser parser)

generate tree factory. Backward compatibility: default factory name.

factory

public static void factory(PrintWriter out,
                           Parser parser,
                           String name)

generate tree factory. If visitor (and optionally param) is set in the properties file the tree factory will implement a visitor pattern.

Parameters:

name - for the tree factory class, Tree if null or empty.

epilog

public static void epilog(PrintWriter out,
                          Parser parser)

output epilog.
