设计模式--抽象工厂模式（C++）

抽象工厂可以理解为简单工厂模式和工厂方法模式的结合，抽象工厂模式拥有多个工厂，每个工厂又可以生产多种产品；可大致理解为简单工厂模式是一个工厂，自己一对多；工厂方法模式是多个工厂，每个工厂一对一；抽象工厂模式是多个工厂，每个工厂一对多；

1.产品接口Human （人类，其子类有黄种人、白种人）

#pragma once
class Human
{
public:
	Human();
	virtual ~Human();
	virtual void character() = 0;
	virtual void Sex() = 0;
private:

};

Human::Human()
{
}

Human::~Human()
{
}

2.抽象产品1 WhiteHuman （白种人，其子类有白种男孩、白种女孩）

#pragma once
#include "Human.h"
#include 
class WhiteHuman:public Human
{
public:
	WhiteHuman();
	virtual ~WhiteHuman();
	void character();
	virtual void Sex()=0;
private:

};

WhiteHuman::WhiteHuman()
{
}

WhiteHuman::~WhiteHuman()
{
}

void WhiteHuman::character()
{
	std::cout << "白种人性格贪婪" << std::endl;
}

2.1 具体产品1 （白种男孩）

#pragma once
#include "WhiteHuman.h"
class WhiteBoyHuman:public WhiteHuman
{
public:
	WhiteBoyHuman();
	~WhiteBoyHuman();
	void Sex();
private:

};

WhiteBoyHuman::WhiteBoyHuman()
{
}

WhiteBoyHuman::~WhiteBoyHuman()
{
}

void WhiteBoyHuman::Sex()
{
	std::cout << "白种男孩的性别是男" << std::endl;
}

2.2 具体产品2 （白种女孩）

#pragma once
#include "WhiteHuman.h"
class WhiteGirlHuman:public WhiteHuman
{
public:
	WhiteGirlHuman();
	~WhiteGirlHuman();
	void Sex();
private:

};

WhiteGirlHuman::WhiteGirlHuman()
{
}

WhiteGirlHuman::~WhiteGirlHuman()
{
}

void WhiteGirlHuman::Sex()
{
	std::cout << "白种女孩的性别是女" << std::endl;
}

3.抽象产品2 YellowHuman（黄种人，其子类有黄种男孩、黄种女孩）

#pragma once
#include "Human.h"
#include 
class YellowHuman:public Human
{
public:
	YellowHuman();
	~YellowHuman();
	void character();
	void Sex()=0;
private:

};

YellowHuman::YellowHuman()
{
}

YellowHuman::~YellowHuman()
{
}


void YellowHuman::character()
{
	std::cout << "黄种人性格温良" << std::endl;
}

3.1 具体产品1 （黄种男孩）

#pragma once
#include "YellowHuman.h"
class YellowBoyHuman:public YellowHuman
{
public:
	YellowBoyHuman();
	~YellowBoyHuman();
	void Sex();
private:

};

YellowBoyHuman::YellowBoyHuman()
{
}

YellowBoyHuman::~YellowBoyHuman()
{
}

void YellowBoyHuman::Sex()
{
	std::cout << "黄种男孩的性别是男" << std::endl;
}

3.2 具体产品2 （黄种女孩）

#pragma once
#include "YellowHuman.h"
class YellowGirlHuman:public YellowHuman
{
public:
	YellowGirlHuman();
	~YellowGirlHuman();
	void Sex();
private:

};

YellowGirlHuman::YellowGirlHuman()
{
}

YellowGirlHuman::~YellowGirlHuman()
{
}

void YellowGirlHuman::Sex()
{
	std::cout << "黄种女孩的性别是女" << std::endl;
}

4.抽象工厂

#pragma once
#include "Human.h"
#include "WhiteHuman.h"
#include "YellowHuman.h"
#include
#include 
class CreatHumanFactory
{
public:
	CreatHumanFactory();
	virtual ~CreatHumanFactory();
	virtual Human* creatWhiteHuman() = 0;
	virtual Human* creatYellowHuman() = 0;
private:

};

CreatHumanFactory::CreatHumanFactory()
{
}

CreatHumanFactory::~CreatHumanFactory()
{
}

5.男人工厂 （生产白种男孩、黄种男孩）

#pragma once
#include "CreatHumanFactory.h"
#include "WhiteHuman.h"
#include "WhiteBoyHuman.h"
#include "YellowBoyHuman.h"
class CreateBoyHumanFactory :public CreatHumanFactory
{
public:
	CreateBoyHumanFactory();
	~CreateBoyHumanFactory();
	Human* creatWhiteHuman();
	Human* creatYellowHuman();
private:

};

CreateBoyHumanFactory::CreateBoyHumanFactory()
{
}

CreateBoyHumanFactory::~CreateBoyHumanFactory()
{
}

Human* CreateBoyHumanFactory::creatWhiteHuman()
{
	return new WhiteBoyHuman();
}

Human* CreateBoyHumanFactory::creatYellowHuman()
{
	return new YellowBoyHuman();
}

6.女人工厂 （生产白种女孩、黄种女孩）

#pragma once
#include "CreatHumanFactory.h"
#include "YellowHuman.h"
#include "WhiteGirlHuman.h"
#include "YellowGirlHuman.h"
class CreateGirlHumanFactory:public CreatHumanFactory
{
public:
	CreateGirlHumanFactory();
	~CreateGirlHumanFactory();
	Human* creatWhiteHuman();
	Human* creatYellowHuman();
private:

};

CreateGirlHumanFactory::CreateGirlHumanFactory()
{
}

CreateGirlHumanFactory::~CreateGirlHumanFactory()
{
}

Human*  CreateGirlHumanFactory::creatWhiteHuman()
{
	return new WhiteGirlHuman();
}

Human* CreateGirlHumanFactory::creatYellowHuman()
{
	return new YellowGirlHuman();
}
