Command Design Pattern C++

Command Design Pattern

// Parameter should contain in type T // if need to use different signature for function pointer use function and bind from Boost. // use union concept and make this can work with function pointer vs class member function pointer.

template <typename T> class command { public: // class member function pointer typedef void(T::*Action)(); Command(T *object=0, Action method=0){ m_object = object; m_method = method; } void execute() { (m_object->*m_method)(); }

// now decide as per your domain //is this copyable or movable or none

private: T *m_object; Action m_method; }
