[Insight-developers] private constructor with argument Self

[Stephen R. Aylward]

Hi,

Question: When do I implement a private contructor that takes a const 
reference to self as an argument?

e.g.,

Class foo
  {
  public:
    stuff...
  private:
    foo(const Self &);
    void operator=(const Self &);
  }

Sometimes these functions are implemented in itk classes....sometimes 
not.   I thought I knew the answer...but...I guess I am 
wrong...Specifically, in ITK it doesn't appear to depend on whether or 
not there are local vars in the class...   I couldn't find anything on 
our web pages or in the software guide...

Thanks,
Stephen
