C++中CSimpleList的完成與測試實例。本站提示廣大學習愛好者:(C++中CSimpleList的完成與測試實例)文章只能為提供參考,不一定能成為您想要的結果。以下是C++中CSimpleList的完成與測試實例正文
本文實例講述了C++簡略列表類的完成辦法。分享給年夜家供年夜家參考。詳細辦法以下:
_AFXTLS.CPP文件以下:
//#include "StdAfx.h #include <stddef.h> #include <stdio.h> #include "_AFXTLS_.H" struct MyThreadData{ MyThreadData* pNext; int nShortData; }; void CSimpleList::AddHead(void *p) { *GetNextPtr(p)=m_pHead; m_pHead = p; } BOOL CSimpleList::Remove(void* p) { BOOL bRet = FALSE; if (p == NULL) { bRet = FALSE; } if (p == m_pHead) { m_pHead = GetNext(m_pHead); bRet = TRUE; } else { void* pTest; pTest = m_pHead; while (pTest && (GetNext(pTest) != p)) { pTest = GetNext(pTest); } if (pTest != NULL) { *GetNextPtr(pTest) = GetNext(p); bRet = TRUE; } } return bRet; } void main() { MyThreadData* pData; CSimpleList list; list.Construct(offsetof(MyThreadData, pNext)); for (int i=0;i<10;i++) { pData = new MyThreadData; pData->nShortData = i; list.AddHead(pData); } //遍歷鏈表,釋放MyThreadData對象占用的空間 pData = (MyThreadData*)list.GetHead(); while(pData != NULL) { MyThreadData* pNextData = pData->pNext; printf("The value is %d\n",pData->nShortData); delete pData; pData = pNextData; } }
_AFXTLS_.H文件以下:
//#include "StdAfx.h #ifndef __AFXTLS_H__ #define __AFXTLS_H__ #include <Windows.h> class CSimpleList { public: CSimpleList(int nNextOffset=0); void Construct(int nNextOffset); //接口 BOOL IsEmpty() const; void AddHead(void *p); void RemoveAll(); void* GetHead() const; void* GetNext(void* preElement) const; BOOL Remove(void* p); //為完成接口所需的成員 void *m_pHead; size_t m_nextOffset; void** GetNextPtr(void* preElement) const; }; //類的內聯函數 inline CSimpleList::CSimpleList(int nNextOffset) {m_pHead = NULL; m_nextOffset = nNextOffset; } inline void CSimpleList::Construct(int nNextOffset) {m_nextOffset = nNextOffset; } inline BOOL CSimpleList::IsEmpty() const { return m_pHead==NULL; } //inline void AddHead(void *p) //{ // //} inline void CSimpleList::RemoveAll() { m_pHead = NULL; } inline void* CSimpleList::GetHead() const { return m_pHead; } inline void* CSimpleList::GetNext(void* preElement) const { return *GetNextPtr(preElement); } //inline BOOL CSimpleList::Remove(void* p) //{ // //} inline void** CSimpleList::GetNextPtr(void* preElement) const { return (void**)((BYTE*)preElement+m_nextOffset); } #endif
