[antlr-interest] Accumulation of return values (Java)

[Thomas Karcher]

Hi,

> 		{ $result = new Term(TEXT, $name.result, XXX); }
> 	;
> The question is, what ought to go in place of XXX in order to

Did you try something like


text_block returns [Term result]
	: ^(TEXT name? phr+=phrase*)
		{ $result = new Term(TEXT, $name.result, $phr); }
	;

Then Term should have a "List" as last parameter type.
