[antlr-interest] Re: Passing OutputStream to Lexer

[spenserkao]

Empirically, I think I've found the alternative for the same goal.
In the Lexer part of the grammar, create a method something like
Public String getOutputMsg() { 
 } to return the outgoing message, 
then in the main program, where Parser and Lexer will be 
instantiated, call the public method to pass the outgoing message to 
PrintWriter.println().

I am answering my own question here:o)
