HEVC代码中定义了几十种类，这些类的对象一般只实例化一次，在编码过程中都是通过指针来访问实例化的对象。
唯一以类名实例化的对象：cTAppEncTop

main ()
{
 TAppEncTop   cTAppEncTop;
}

这个对象被建立时，它的所有数据成员也被建立，并实例化（占据存储空间）

class TAppEncTop
{
    TEncTop  m_cTEncTop
}

而m_cTEncTop这个数据成员，本身作为一个对象，它自己的数据成员也被建立并实例化

class TEncTop : public TEncCfg
{
private:
  // picture
  Int                     m_iPOCLast;                     ///< time index (POC)
  Int                     m_iNumPicRcvd;                  ///< number of received pictures
  UInt                    m_uiNumAllPicCoded;             ///< number of coded pictures
  TComList<TComPic*>      m_cListPic;                     ///< dynamic list of pictures

  // encoder search
  TEncSearch              m_cSearch;                      ///< encoder search class
  //TEncEntropy*            m_pcEntropyCoder;                     ///< entropy encoder
  TEncCavlc*              m_pcCavlcCoder;                       ///< CAVLC encoder  
  // coding tool
  TComTrQuant             m_cTrQuant;                     ///< transform & quantization class
  TComLoopFilter          m_cLoopFilter;                  ///< deblocking filter class
  TEncSampleAdaptiveOffset m_cEncSAO;                     ///< sample adaptive offset class
  TEncEntropy             m_cEntropyCoder;                ///< entropy encoder
  TEncCavlc               m_cCavlcCoder;                  ///< CAVLC encoder
  TEncSbac                m_cSbacCoder;                   ///< SBAC encoder
  TEncBinCABAC            m_cBinCoderCABAC;               ///< bin coder CABAC
  TEncSbac*
