中介者模式和命令模式

標籤：中介者模式   命令模式   

1、中介者模式

  就是借用一個中間的類,來完成其他2個類之間要實現的功能!!!

2、具體實現

  (1)、代碼如下

#include<string>using namespace std;class Mediator{    public:        virtual void getParent() = 0;    private:};class contreMediator{    public:    private:};  class Person{    public:        Person(string name, int sex, int condi){            m_name = name;            m_sex = sex;            m_condi = condi;        }        string getName(){            return m_name;        }        int getSex(){            return m_sex;        }        int getCondi(){            return m_condi;        }        virtual void getParent(Person *p) = 0;    protected:        string m_name;        int m_sex;        int m_condi;};////////////////////////////////////////////////////////////////////////////////////////////class Woman : public Person{    public:        Woman(string name, int sex, int condi) : Person(name, sex, condi){        }        void getParent(Person *p){            if(this->m_sex == p->getSex()){                cout<<"不是同性戀"<<endl;               }            if(this->getCondi() == p->getCondi()){                cout<<this->getName()<<"和"<<p->getName()<<"絕配"<<endl;            }else{                cout<<this->getName()<<"和"<<p->getName()<<"不配"<<endl;            }        }    private:};//////////////////////////////////////////////////////////////////////////////////////////////////class Man : public Person{    public:        Man(string name, int sex, int condi) : Person(name, sex, condi){        }        void getParent(Person *p){            if(this->m_sex == p->getSex()){                cout<<"不是同性戀"<<endl;            }            if(this->getCondi() == p->getCondi()){                cout<<this->getName()<<"和"<<p->getName()<<"絕配"<<endl;            }else{                cout<<this->getName()<<"和"<<p->getName()<<"不配"<<endl;            }             }    private:};int main(void){    Person *xiaofang = new Woman("小芳", 2, 5);    Person *zhangsan = new Man("張三", 1, 4);    Person *lisi = new Man("李四", 1, 5);    xiaofang->getParent(zhangsan);    xiaofang->getParent(lisi);    return 0;}

  (2)、運行結果

3、命令模式

 把一個動作進行分解,分成發行者和接受者;

4、具體實現

  (1)代碼如下

#include<iostream>using namespace std;class Doctor{    public:        void treatEye(){            cout<<"醫生 治療 眼病"<<endl;        }           void treatNose(){            cout<<"醫生 治療 鼻科病"<<endl;        }       private:};class Command{    public:        virtual void treat() = 0;    private:};class CommandTreatEye : public Command{    public:        CommandTreatEye(Doctor *doctor){            m_doctor = doctor;        }        void treat(){            m_doctor->treatEye();        }    private:        Doctor *m_doctor;};class CommandTreatNose : public Command{    public:        CommandTreatNose(Doctor *doctor){            m_doctor = doctor;        }        void treat(){            m_doctor->treatNose();        }    private:        Doctor *m_doctor;};class BeautyNurse{    public:        BeautyNurse(Command *command){            this->command = command;        }    public:            void SubmittedCase(){  //提交病類, 下單命令            command->treat();        }    private:        Command *command;};int main(void){    /*    //1、醫生直接看病    Doctor *doctor = new Doctor;    doctor->treatEye();    delete doctor;    */    /*    //2、通過一個命令    Doctor *doctor = new Doctor;    Command *command = new CommandTreatEye(doctor);    command->treat();    delete command;    delete doctor;    */    //護士提交簡曆,醫生看病;    Doctor *doctor = new Doctor;//  Command *command = new CommandTreatEye(doctor);    Command *command01 = new CommandTreatNose(doctor);    BeautyNurse *beautyNurse = new BeautyNurse(command01);    beautyNurse->SubmittedCase();    delete doctor;    delete command01;    delete beautyNurse;    return 0;}
