I have implemented the following interface:
template <typename T>
class Variable
{
public:
Variable (T v) : m_value (v) {}
virtual void Callback () = 0;
private:
T m_value;
};
A proper derived class would be defined like this:
class Derived : public Variable<int>
{
public:
Derived (int v) : Variable<int> (v) {}
void Callback () {}
};
However, I would like to derive classes where Callback accepts different parameters (eg: void Callback (int a, int b)). Is there a way to do it?
