[antlr-interest] Token Ranges in TreeParser: possible

[aanno]

Hello,

I tried the following: I fixed the token types with *TokenTypes.txt 
in a TreeParser. Everything just works fine except when I tried to 
use a TOKEN RANGE (ie. (TOKEN_1 .. TOKEN_2)). There is no complaint 
from ANTLR 2.7.1, but its generated code can't be compiled by javac. 
There 
is a line like:

match(TOKEN_1, TOKEN_2);

there match(..) is not a method of TreeParser.

This are my questions:

1. Is it possible to have token ranges at all or are ranges limited 
to lexers?
2. Is there a way to define the method match(..) so that the token 
range just works fine?
3. Is it the same for not matches like in (~TOKEN_1).

By the way, apart from this problem, I think ANTLR is a great tool.

Cheers,

Thomas
