position of productions.

["Brandner Florian" <flopsi@hotmail.com>]

Hallo,

 

I have a gramma with something like an assignment statement in it like this:

p = a ':=' b;

 

a and b are typed and these types must be identical, to get a valid assignment.

If this is not the case i want to emit an error message, with the position of production p.

 

Is it posible to get the line and position of an production (like the Token.getLine() and Token.getPos() )?
