「设计模式」 抽象工厂

抽象工厂

//单核

class SingleCore

{

public:

virtual void Show() = 0;

};

class SingleCoreA: public SingleCore

{

public:

void Show() { cout<<"Single Core A"<<endl; }   

};

class SingleCoreB :public SingleCore

{

public:

void Show() { cout<<"Single Core B"<<endl; }   

};

//多核

class MultiCore

{

public:

virtual void Show() = 0;

};

class MultiCoreA : public MultiCore

{

public:

void Show() { cout<<"Multi Core A"<<endl; }   

};

class MultiCoreB : public MultiCore

{

public:

void Show() { cout<<"Multi Core B"<<endl; }   

};

//工厂

class CoreFactory

{

public:

virtual SingleCore* CreateSingleCore() = 0;

virtual MultiCore* CreateMultiCore() = 0;

};

//工厂A，专门用来生产A型号的处理器

class FactoryA :public CoreFactory

{

public:

SingleCore* CreateSingleCore() { return new SingleCoreA(); }   

MultiCore* CreateMultiCore() { return new MultiCoreA(); }   

};

//工厂B，专门用来生产B型号的处理器

class FactoryB : public CoreFactory

{

public:

SingleCore* CreateSingleCore() { return new SingleCoreB(); }   

MultiCore* CreateMultiCore() { return new MultiCoreB(); }   

};

简单工厂模式和模板方法的区别？
