[antlr-interest] declare throws-clause for rule

[tilman walter]

Hi List,

I am a newby to antlr.
Is there a possibility to let a rule throw a custom exception that can 
be catched by the class invoking the parser?
I think i could place this piece of code in the generated class, but i 
wonder if i can reach this through a grammar construct....

I would appreciate for any hint.
Thanks is advance.

Tilman
