[antlr-interest] Why CommonTreeNodeStream.index() always returns 0?

[Frank Du]

Hi All,

I am using antlr-3.1.3. The problem is that, all the time TreeNodeStream.index() returns 0. Apparently it is not what we expected. I wish to define function and remember its entry position. Is it a bug in 3.1.3, or do I need any configuration? The related interpreter example and my comment:

Thank you so much!
