[antlr-interest] Collecting Values in Lists

[Behdad Forghani]

Hello,

In the grammar I am working on I have a lot of list items like:

x :
 y (',' y)*;

The rule y appears under other nodes. Now, when I am building my data
structure I am doing the following:

x
scope {
ArrayList<XType> list;
}
:
 xCollecty (',' xCollecty)*;

xCollectY :
  y 
  {
    $x::list.add($y.value);
  }
;

y
returns [value YType]
 token :
  {
      $value = ...;
  }
;

Is there a better way of doing this?

Thanks,
Behdad
