These classes do not have to inherit from some interface or base class which provides a prototype for the serialize-to-asn-1 method. Such a requirement has more to do with static typing than object oriented programming. Usually in languages which require such inheritance, there are also statically typed references. A class must conform to some "ASNEncodable" class so that its instances can be passed to functions which expect references to an ASN1Encodable type, which is verified at compile time. |
