[antlr-interest] Return Values

[Philip Mötteli]

Hi,


I know, how to access a return value from a parser rule/token: By calling "$rule.returnValue". E. g:

parserRule0	:	parserRule1
				{	DoSomethingWithTheReturnValue($parserRule1.returnValue);	}
			;


But how do I access the return value, if it's one of several options ('or'ed together):

parserRule0	:	aParserToken=( parserRule1 | parserRule2 | parserRule3 )
				{	// How do I access "$aParserToken.returnValue"?	}
			;


Thanks for any help
