设计模式的解析和实现(C++)之二-Abstract Factory模式

作者 佚名技术 来源 程序设计 浏览 发布时间 2012-06-29
实现
class ConcreateFactory1
    : public AbstractFactory
{
public:
    ConcreateFactory1();
    virtual ~ConcreateFactory1();

    virtual AbstractProductA* CreateProductA();
    virtual AbstractProductB* CreateProductB();
};

// 派生类ConcreateFactory2,继承自AbstractFactory
// 生产产品A和产品B的第二种实现
class ConcreateFactory2
    : public AbstractFactory
{
public:
    ConcreateFactory2();
    virtual ~ConcreateFactory2();

    virtual AbstractProductA* CreateProductA();
    virtual AbstractProductB* CreateProductB();
};

#endif

2)AbstractFactory.cpp
