[C++知识库]设计模式之原型模式

个人理解

类中提供了复制类的函数，能够在你需要他的副本的情况下快速的创建出一个相同的类来。

原型模式

#include<iostream>
using namespace std;

class Clone
{
public:
	virtual Clone* clone() = 0;
	virtual void eat() = 0;
};

class person : public Clone
{
public:
	person(string name)
	{
		this->m_name = name;
	}

	person(const person& other)
	{
		this->m_name = other.m_name;
	}

	Clone* clone()
	{
		return new person(*this);
	}


	void eat()
	{
		cout << m_name << " is a foodie" << endl;
	}
private:
	string m_name;
};

int main()
{
	Clone* woman = new person("xiaozhang");
	Clone* woman_1 = woman->clone();
	woman->eat();
	woman_1->eat();
	if (woman)
	{
		delete woman;
		woman = NULL;
	}
	if (woman_1)
	{
		delete woman_1;
		woman_1 = NULL;
	}
	return 0;
}
