Re: Node
Hi Yuntao,
This is similar to what I was talking about in a previous post to this
mailing list:
http://www.sable.mcgill.ca/listarchives/sablecc-list/msg00792.html
Although, if you want to add the method to the Node class you might find
it easier to just edit the generated file. Maybe you could write a shell
script or Makefile to do it for you every time you run sablecc.
A last approach is to write an interface for the extended nodes which
includes the method, and then make sure you extend each node [1] and
have a copy of the method in each. I used the C preprocesser (#included
the method in each node) to do this and it works quite well but the
makefile is a bit of a pain
(http://roger.ninthave.net/software/snippets/java/makefile.inc).
Good luck!
Rog
[1] you need to hack the sablecc source and remove the final keyword in
order to extend generated classes (see link above).
