Factory.h
#ifndef FACORY_H
#define FACTORY_H
class product
{
public:
product(){}
virtual ~product(){}
};
class ConcreateProduct : public Product
{
public:
ConcreateProduct();
virtual ~ConcreateProduct();
};
class Creator
{
public:
Creator(){}
virtual ~Creator(){}
void AnOperation();
protected:
virtual product *FactoryMethod()=0;
};
class ConcreateCreator :public Creator
{
public:
ConcreateCreator();
virtual ~ConcreateCreator();
protected:
virtual Product * FactoryMethod();
};
#endif
