AW: position of productions.

["Thomas Leonhardt" <leonhardt@informatik.tu-darmstadt.de>]

What I'm doing in this case is to check the actual type in the

in or out method of my visitor, like:

 

if( node instanceof alternative_one )

{

}

else

if( node instanceof alternative_two )

{

}

 

I do this until I get an token at one point. It's not nice but it works.

I do it for java source analysis to get the position of method usages and

such.

 

Cheers,

Thomas

Betreff: position of productions.

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() )?

 

Florian
