I find it hard to think of one more function that would be added and not be under the control of a % directive.
But if the Bison user defines his own class to wrap the parser class (like the parser driver), he can create whatever interface he likes for the parser user.
I think if we can live without the parser driver, it is better (and the fact that Java uses only virtual methods makes me believe this is the case). I don't know of other parser generators for Java that require a parser driver.
