[antlr-interest] Generic parser class

[Sam Harwell]

One possibility is you could derive a generic class from your parser, and place your action code in it. Create empty virtual functions in the parser itself as the placeholder for the actions. Does that cover what you need?

I just need a type parameter for the class.  Currently, I have a sed
script replacing 

public class XXXParser extends Parser { ... }

with

public class XXXParser<P extends Foo> extends Parser { ... }

That's exactly what I need done: The Java action code refers to that
type parameter.
