Command

Общая реализация на языке С++

Command

template <typename Reseiver>
class Command
{
public:
	virtual ~Command() = default;
	
	virtual void execute(shared_ptr<Reseiver>) = 0;
};

ConcreteCommand

template <typename Reseiver>
class ConcreteCommand : public Command<Reseiver>
{
	using Action = void(Reseiver::*)();
private:
	Action act;

public:
	ConcreteCommand(Action a) : act(a) {}

	virtual void execute(shared_ptr<Reseiver> r) override { ((*r).*act)(); }
};

Object

class Object
{
public:
    virtual void run() = 0; 
};

ConcreteObject

class ConcreteObject : public Object
{
public:
	virtual void run() override 
	{ 
		cout << "Run method;" << endl; 
	}
};
