Factory Pattern（C++实现）
/*Product.h*/
#ifndef PRODUCT_H
#define PRODUCT_H
class Product
{
public:
virtual ~Product()=0;
protected:
Product();
private:
};
class ConcreteProduct:public Product
{
public:
~ConcreteProduct();
ConcreteProduct();
protected:
private:
};
#endif
/*Product.cpp*/
#include "Product.h"
#include <iostream>
Product::Product()
{
}
Product::~Product()
{
}
ConcreteProduct::ConcreteProduct()
{
std::cout<<"ConcreteProduct..."<<std::endl;
}
ConcreteProduct::~ConcreteProduct()
{
}
/*Factory.h*/
#ifndef FACTORY_H
#define FACTORY_H
class Product;
class Factory
{
public:
virtual ~Factory()=0;
virtual Product *CreateProduct()=0;
protected:
Factory();
private:
};
class ConcreteFactory:public Factory
{
public;
~ConcreteFactory();
ConcreteFactory();
Product *CreateProduct();
protected:
private:
};
#endif
/*Factory.cpp*/
#include "Factory.h"
#include "Product.h"
#include <iostream>
Factory::Factory()
{
}
Factory::~Factory()
{
}
ConcreteFactory::ConcreteFactory()
{
std::cout<<"ConcreteFactory..."<<std::endl;
}
ConcreteFactory::~ConcreteFactory()
{
}
Product *ConcreteFactory::CreateProduct()
{
return new ConcreteProduct();
}
/*main.cpp*/
#include "Factory.h"
#include "Product.h"
#include <iostream>
int main()
{
Factory *fac=new ConcreteFactory();
Product *p=fac->CreateProduct();
return 0;
}
