软件设计⑩①|装饰模式

一、类图

二、效果

三、代码

#include<iostream>
using namespace std;

//公共抽象类
class Phone {
public:
    virtual void voice() {}
};

//SimplePhone
class SimplePhone :public Phone {
private:
    string phone;//手机
public:
    SimplePhone(string phone) :phone(phone) {}
    void voice() {
        cout << "来电声音提示" << endl;
    }
};

//装饰类
class PhoneDecorator :public Phone {
private:
    Phone* phone;//要装饰的手机
public:
    PhoneDecorator(Phone* phone) :phone(phone) {}
    virtual void voice() {
        phone->voice();
    }
};

//ComplexPhone
class ComplexPhone :public PhoneDecorator {
public:
    ComplexPhone(Phone* phone) :PhoneDecorator(phone) {}
    void voice() {
        cout << "来电声乐提示" << endl;
    }
    void shake() {
        cout << "来电振动提示" << endl;
    }
    void light() {
        cout << "来电灯光提示" << endl;
    }
};

//JarPhone
class JarPhone :public PhoneDecorator {
public:
    JarPhone(Phone* phone) :PhoneDecorator(phone) {}
    void voice() {
        cout << "来电声乐提示" << endl;
    }
    void shake() {
        cout << "来电振动提示" << endl;
    }
};

int main() {
    cout << "SimplePhone" << endl;
    Phone* phone = new SimplePhone("SimplePhone");
    phone->voice();
    cout << endl;
    cout << "JarPhone" << endl;
    JarPhone* phone1 = new JarPhone(phone);
    phone1->voice();
    phone1->shake();
    cout << endl;
    cout << "ComplexPhone" << endl;
    ComplexPhone* phone2 = new ComplexPhone(phone);
    phone2->voice();
    phone2->shake();
    phone2->light();
}
