抽象工厂模式（AbstractFactory）和反射技术（Reflect）都在前面的笔记中记录了，现在将两个功能结合起来。还是以快餐店的食品为例子。

首先，有快餐店的食品作为产品的基类，然后有鸡腿和汉堡两类食品，而鸡腿和汉堡又分肯德基的和麦当劳的。肯德基和麦当劳的汉堡和鸡腿是不同的，也就是说是不同的实现类型，合乎抽象工厂的使用场合。

下面看具体的实现代码：

// ReflectFactory.h#pragma once#include 
   
    typedef void* (*lpCreateInstanceFun)();typedef struct tagClassInfoData{    std::string strClassName;    lpCreateInstanceFun pFun;    tagClassInfoData* pNext;}ClassInfoData;class CReflectFactory{private:    static ClassInfoData* pData;    static ClassInfoData* pHead;    static CReflectFactory _tmp_;public:    CReflectFactory(void);    ~CReflectFactory(void);    static void AddInstance(const std::string& strClassName, lpCreateInstanceFun pFun);    static void* GetInstance(const std::string& strClassName);};#define DECLARE_REFLECT(CLASS_NAME) private:\    static void* _CreateInstance_(){ return new CLASS_NAME(); }\    static wchar_t _m_AddFunc_;\    static wchar_t _AddFunc_() { CReflectFactory::AddInstance(#CLASS_NAME, &_CreateInstance_); return 0; }#define IMPLEMENT_REFLECT(CLASS_NAME) wchar_t CLASS_NAME::_m_AddFunc_ = _AddFunc_();// ReflectFactory.cpp#include ".\ReflectFactory.h"ClassInfoData* CReflectFactory::pData = NULL;ClassInfoData* CReflectFactory::pHead = NULL;CReflectFactory CReflectFactory::_tmp_;CReflectFactory::CReflectFactory(void){}CReflectFactory::~CReflectFactory(void){    ClassInfoData* pFind = pHead;    while ( pFind != NULL )    {        pFind = pHead->pNext;        delete pHead;        pHead = pFind;    }}void CReflectFactory::AddInstance(const std::string& strClassName, lpCreateInstanceFun pFun){    if ( NULL != pFun )    {        if ( NULL == pData )        {            pData = new ClassInfoData();            pHead = pData;        }        else        {            pData->pNext = new ClassInfoData();            pData = pData->pNext;        }        pData->strClassName = strClassName;        pData->pFun = pFun;        pData->pNext = NULL;    }}void* CReflectFactory::GetInstance(const std::string& strClassName){    std::string str = strClassName;    ClassInfoData* pFind = pHead;    while ( pFind != NULL )    {        if ( str == pFind->strClassName )        {            return pFind->pFun();   // 这个括号别再忘了        }        pFind = pFind->pNext;    }    return NULL;}//Product.h#ifndef _PRODUCT_H_#define _PRODUCT_H_#include
