[webkit-dev] Interface design question
Hello, Have a design related question and hope to hear some insights. Interfaces using abstract classes impose restriction(s) on it's derived implementations. - The most widely used restriction is to IMPLEMENT Function(s) Question: Is it permissible to have similar kind of restriction for any data members in the interface? In a way that if some one wants to implement the interface it also must initialize certain variable. Ex: Say for a TCP/IP it absolutely necessary to have peer's IP address and Port number. So, is wise to impose a restriction to pass above variable to initialize the class. class IP4Connection { public: explicit IP4Connection( string ip, uint port); virtual int send() = 0; virtual int listen() = 0; virtual int reconnect() = 0; protected: std::string ip; uint port; }; Thanks, Siva.___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev

webkit-dev doesn't seem like an appropriate place to discuss this topic unless you have a specific WebKit patch or bug that relates this design question.
