一个很好用的模板（截取网络数据包）

template <typename T, int minsize = sizeof(T)> 
class Analizer
{
private:
   const char* m_pccPacket;
   int  m_Size;
   static const int M_MIN_SIZE = minsize;
public:
   void Bind(const char* pccPacket, int size)
   {
  m_pccPacket = pccPacket;
  m_Size = size;
   };
   bool IsValidate() const
   {
  if(m_Size >=  M_MIN_SIZE)
  {
   return true;
  }
  else
  {
   return false;
  }
   }
   const T* GetObject() const
   {
   if(IsValidate())
   {
   return (T*) m_pccPacket;
   }
   else
   {
   return NULL;
   }
   }
};
