Hello,

A message has been sent to the antlr-interest group from

The message summary:

SUBJECT: Custom Exception? 

Hi all, 

Is it possible that in each rule we can throw custom 
exceptions other than modifying the generated code directly?
What I mean is: 

MyRule {action} returns [type retval] throws MyException1, 
MyException2 : declaration { // we can throw MyException1 or
MyException2 and eliminate // the need to catch the 
exception and convert it. } ;
