今天的微博有人討論到對象池，我想到之前項目的實現，應該用模板來實現啊，唉，還是被前人的想法給框定了，只是實現一個特別簡單，花了幾分鐘寫了個：

const int DefaultPoolSize = 1024; template <class T> class CSSObejctPool{ private:queue<T*> m_OriBlock;queue<T*> m_ObjectBlock;const INT32 m_DefaultBlockSize; public:~CSSObejctPool(){while (!m_OriBlock.empty()){T* pBlock = m_OriBlock.front();delete []pBlock;m_OriBlock.pop();}}CSSObejctPool(INT32 blockSize = DefaultPoolSize):m_DefaultBlockSize(blockSize){}T* GetObject(){if (true == m_ObjectBlock.empty()){T* pNewObject = new T[m_DefaultBlockSize];m_OriBlock.push(pNewObject);for (int i = 0; i < m_DefaultBlockSize; ++i){m_ObjectBlock.push(pNewObject+i);}}T* pGetObject = m_ObjectBlock.front();m_ObjectBlock.pop();return pGetObject;}void ReleaseObejct(T* pObject){if (0 == pObject){return;}m_ObjectBlock.push(pObject);}void Clear(){while (!m_ObjectBlock.empty()){T* pObject = m_ObjectBlock.front();pObject->Clear();m_ObjectBlock.pop();}queue<T*> tempBlock;while (!m_OriBlock.empty()){T* pBlock = m_OriBlock.front();for (INT32 i = 0; i < m_DefaultBlockSize; ++i){m_ObjectBlock.push(pBlock + i);}tempBlock.push(pBlock);m_OriBlock.pop();}m_ObjectBlock = tempBlock;} };

等下再實現個線程安全的。
