[antlr-interest] Follow-up on line numbers

[David Smith]

Sam,
I understood the answer, but we're talking novice here - if the front 
end of my grammar looks like this:

prog:   body EOF!
         ;

body    :
         parts -> ^(BODY parts)
         ;

parts   :
         ( (stat
            | ifStat
            | switchStat
            | whileStat
            | forStat)   )*
         ;

stat:
         (ID OPENP actualParameters CLOSEP DOT ID GETS)
          => str=ID OPENP actualParameters CLOSEP  DOT fld=ID GETS expr
          -> ^(GETS ?????? ^(STRUCTA $str $fld actualParameters) expr)
     |   (ID OPENP actualParameters CLOSEP DOT OPENP)
          => str=ID OPENP actualParameters CLOSEP DOT OPENP var=ID 
CLOSEP GETS expr
          -> ^(GETS ???????? ^(STRUCTAV $str $var actualParameters) expr)
// etc
     ;
how would I insert the line number at the ???????

It seems that the parse tree generated by the parser has a data field
'line' that seems to correspond to the source line when parsing.  How
do i access that to include the line number in the tree generated by
my grammar?

Both the Tree and Token interfaces have a method getLine().
