有没有办法在antlr语法文件中指定Java注释？

Question

I'm looking for a way to include a few additional strings in output .java files generated from antlr. Is there a comprehensive listing of available directives? For example, given parser output like this:

package com.foo.bar; //<-- this can be generated with @header { .... }
//antlr generated
import org.antlr.runtime.*; 
...

//<-- is there a way to generate anything here?
public class MyParser {

    //<--- or here?
    public void f1(){ ... }

}

Is there a way to generate strings that appear after the import statements (eg class-level annotations) or possibly method annotations?

To the best of my knowledge, you cannot do this. The book doesn't mention anything. Maybe you can ask at the mail list : antlr-interest@antlr.org
