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._______________________________________________
