[antlr-interest] How to add code to the Parser class?

[jduquevieira]

To have more control over the parsing I added some Semantic 
Predicates to my Gramar.

These predicates rely on a Variable. The Variable has to known to 
all the rules.

How can I set this Variable as a member of the Parser class of my 
Gramar? I don't seem to find out how, except opening the generated 
Parser file and adding the Variable as a Member.

This way, everytime I change the Gramar and the Parser class is 
reconstruted, I need to edit it and insert a line of code declaring 
the Variable.

Is there any other way to do this?

Thanks a lot.
