So this strikes me as a fairly common problem. If I was going to solve it I don't think i would use a "dispatch table" I wold prefer to use polymorphism. In C# maybe i would have an interface with the common method. An abstract class to provide a default implementation. Then several classes which either implement the interface directory, or inherit the abstract class.
