[antlr-interest] error handling

[Bharath Sundararaman]

Hi Lance,

Did you visit http://www.antlr.org/doc/err.html#_bb1 yet? That should be
your first stop.

I catch parser exceptions from my main java program (the code which
calls the lexer, parser, tree walker and prints the ast), extract
relevant information presented by each exception (API:
http://www.antlr.org/javadoc/antlr/ANTLRException.html) and create my
own exception based on my app needs.

This is probably a simple question.  I want to report parse errors to
the 
user.  The parser throws an exception.  Which one do I catch and what 
information about the position and nature of the error is there?  If 
someone could point me to some documentation on this subject I would be 
grateful.

Thanks
Lance
