Java or C++?  The source is all there.  You should be able to dig into the
base class and see what it does.

Subject: [antlr-interest] Help: writing your own scanner with antlr


Hello,
For some reasons I need to interface my own scanner with my antlr 
grammar. The standard interface between scanner and parser in Antlr 
seems to be through an object Token and getToken() method that 
returns the next token within the stream.

I have problems achieving this. I use Token.setText() method to set 
the text field within the scanner but it does not work. I have no way 
to find out exactly how the antlr-generated scanner does it, because 
I only know that the tokens actually get created through base class 
that Antlr-scanner inherits so it happens "behind the scenes".

Can you please let me know any way to do this? If needed, I can 
provide more info, and we could take this discussion offline.

Thanks a lot for all the help,
Medha
