[antlr-interest] accessing multiple return values

[Des Hartman]

I have an interesting problem. I have written a tree parser for Actionscript
and in it I call external code to convert a reference from Stirng to Number.
I also calculate additional attributes of this reference (Type and format)
The details of the actual reference call is not really relevant. the code
snippets look like this:

@members{
public function
evaluateInternalReference(ref:CommonTree):TreeRuleReturnScope {return null;}

}

reference returns [Object value, String formulaType, String formatString]
    : ^(IREF ir=INT )                {     $value         =
(evaluateInternalReference($ir) as TreeRuleReturnScope).values.value;
                                            $formulaType     =
(evaluateInternalReference($ir) as TreeRuleReturnScope).values.formulaType;
                                            $formatString     =
(evaluateInternalReference($ir) as
TreeRuleReturnScope).values.formatString;}

I am now converting this same Tree Grammar to Java and having a tough time
doing the same thing. Could someone help me out here with what I think
should be a simple solution? I need to somehow access value, formulaType and
formatString as I did above, but in Java?

@members{
public TreeRuleReturnScope evaluateInternalReference(CommonTree ref) {return
null;}
}

reference returns [Object value, String formulaType, String formatString]
    : ^(IREF ir=INT )                {     $value         =
(TreeRuleReturnScope)(evaluateInternalReference($ir)).values.value; ?????


Thanks
