[Insight-users] I have some problem about the ITK code , the Register() method in itkSmartPointer.h

[zhq]

Hello , All 
       In the itkSmartPointer.h , the SmartPointer class has a method , Register() ,shown as follow 
  void Register()
  {
    if ( m_Pointer ) { m_Pointer->Register(); }
  }
the m_Pointer is a member variable of SmartPoint  ,  but what's the effect of the method ? I think the method just call a Register() , and don't do something meaningfully ?
