[antlr-interest] How to tell antlr to use stg in generated __Test__.java?

[John Leung]

Thanks for the fast reply!

I tried to do my own test rig exactly the same as is in the book, but I'm
getting the following compilation error msg:

incompatible types
found: java.lang.Object
Required: org.antlr.stringtemplate.StringTemplate
  StringTemplate output = r.getTemplate();
                                                         ^

I found the reason for this is that the generated parser.java declares
getTemplate() to be:
        public Object getTemplate() { return st; }

Do you know why it's not declared as StringTemplate instead?

thanks,
john
