copy constructor

[Scorpio]

can I prevent any copy constructor being called for my class.

[Cedric Moonen]

Yes, just make it private (or protected).

Then it won't compile.

It won't compile if somebody that uses your class tries to use the copy constructor. So, that was the purpose of his question no ? Preventing people to copy the class. Maybe I misunderstood the question :doh:

Maybe your suggestion is what he needed. I was thinking if he was trying to seek a method which redirects copy ctor to other methods ...

I think not. The same guy asked about the Singleton pattern a few threads down and the correct way to implement the Singleton pattern is to declare constructors, copy constructor and the assignment operator as protected or private. A compile time error is expected if the class implemented as a singleton is used in a way it shouldn't. -- Roger

Hi !!! If you don't define copy constructor in your class, the compiler creates one automatically. YOu cannot prevent that the compiler creates one, but you can implement one with aan empty body. By !!! -:KNOX:-
