设计模式之 原型模式(prototype)(C++实现 深拷贝 + 浅拷贝版本[bug])_c++原型模式深克隆

本文介绍设计模式中的原型模式。

本质上其实就是克隆。

下面以个人简历为例进行举例说明：

深拷贝版本：

#include <iostream>
#include <string>
#include <memory>
 
using namespace std;
 
template<class T>
class ICloneable
{
public:
	virtual T* clone() = 0;
};
 
class CWorkExperience
{
public:
	CWorkExperience(){}
 
	CWorkExperience(const string& company,
		const string& workTime)
	{
		m_strCompany = company;
		m_strWorkTime = workTime;
	}
 
	CWorkExperience(const CWorkExperience& right)
	{
		m_strCompany = right.m_strCompany;
		m_strWorkTime = right.m_strWorkTime;
	}
 
	~CWorkExperience()
	{
		cout << "CWorkExperience析构" << endl;
		printInfo();
	}
 
	void setCompany(const string& company)
	{
		m_strCompany = company;
	}
 
	const string& getCompany() const
	{
		return m_strCompany;
	}
 
	void setWorkTime(const string& workTime)
	{
		m_strWorkTime = workTime;
	}
 
	const string& getWorkTime() const
	{
		return m_strWorkTime;
	}
 
	void printInfo()
	{
		cout << "Company: " << m_strCompany << endl;
		cout << "WorkTime: " << m_strWorkTime << endl;
	}
 
private:
	string m_strCompany;		// company name
