今天的微博有人讨论到对象池，我想到之前项目的实现，应该用模板来实现啊，唉，还是被前人的想法给框定了，不过实现一个特别简单，花了几分钟写了个：

#include 
  
   
#include 
   
     using namespace std; const int DefaultPoolSize = 1024; template 
    
      class ObejctPool{ private: queue
     
       m_OriBlock; queue
      
        m_ObjectBlock; const int m_DefaultBlockSize; public: ~ObejctPool(){ while (!m_OriBlock.empty()){ T* pBlock = m_OriBlock.front(); delete []pBlock; m_OriBlock.pop(); } } ObejctPool(int 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); } }; int main(){ ObejctPool
       
         obj; int* p = obj.GetObject(); *p = 1; printf("get:%d\n", *p); obj.ReleaseObejct(p); }
