初学设计模式之命令模式

命令模式的代码例子

#include<iostream>
using namespace std;
class team1
{
public:
    void DoSomeing()
    {
        cout<<"做一些事情"<<endl;
    }
};

class team2
{
public:
    void DoSomeing()
    {
        cout<<"做一些事情"<<endl;
    }
};

class team3
{
public:
    void DoSomeing()
    {
        cout<<"做一些事情"<<endl;
    }
};

class Command
{
protected:
    team1 m_team1;
    team2 m_team2;
    team3 m_team3;
public:
    virtual void exec()
    {};

};

class ConcreteCommand1:public Command
{
public:
    void exec()
    {
        m_team1.DoSomeing();
    };

};
class Invoker
{
private:

    void Action()
    {

int main()
