[antlr-interest] Knowing line and position in tree parser

I'm doing type checking within a Tree Grammar and want to include line and
position (if possible) of where the error was.

For example:

int i = "a";

When analysing the expression part the type won't match so I want to emit an
error saying "type missmatch in X:Y" where X would be the line number and Y
the position where the error happened.

I don't know where to start searching in the API. I think an example would
be much better.

Thanks!
