How to Disable Further Derivation of a Class

How to Disable Further Derivation of a Class

In some rare cases, it is useful to disallow further derivation of a class. Classes that implement system API or sensitive security management are good examples for that. Declaring the constructor as private prohibits any further derivation of that class.

 class Firewall { 	public: 		bool isAdressValid( const IP_address& ip);private: Firewall() {}//private constructor disables further derivation from this class};

If you’re familiar with Java, it has the same effect as declaring a class as final.
