[antlr-interest] Conditional grammar

[Jose Juan Tapia]

How can make it so that certain parts of my grammar are only executed when a
certain condition is met. For example,

method1:
(myCondtion? INT) STRING;


method1 would require that INT STRING if myCondition evaluates to true. And
only STRING otherwise. I know I've seen this
somewhere in the ANTLR reference but for the life of me I can't find it
again. And all my google searches through the newsgroup leads to conditional
tree rewrite or something similar.
