「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?
