Folks
Can anyone tell me quick if this makes sense... I have grammar A that imports
B. I want to reuse the A parser so I call
AParser.setTokenStream(input);
Thing is setTokenStream() is inherited from Parser and by default does not
communicate with delegate parsers. Should I override in AParser with
public void setTokenStream(TokenStream input) {
super.setTokenStream(input);
gB.setTokenStream(input);
}
where gB is the delegate parser in AParser?
And a feature request... I use grammar imports quite extensively and have
already run into an issue where I needed a method in a parser to get its
delegate parsers. Is there some fundamental barrier to providing such a method
on Lexer, Parser, and TreeParser that would return some collection of delegate
parsers/lexers/tree parsers?
