    Dear exterminator, I got your point now and it seems valid. May be some want to implement that way.

    In such case, yes, the container class can be created on heap there by making this class object aslo...

    Re: Why override new/delete operator?

    Dear NMTop40, Unfortunately it is not true. When the constructor of this class is held private, there is no way objects of this class can be contained in another class.

    Thanking you,
    Yours,...

    Re: Is this bad design???

    Dear exterminator, Since the calls are resolved at run-time based on the object type (and not based on pointer type), and since at run-time there is no access checking (such as private/public etc...)...

    Re: Is this bad design???

    Dear Vedam Shashank, Ofcourse you should. The call should resolve to derived class and not base class, due to Run-time polymorphism.

    Re: Why override new/delete operator?

    Dear Rigel,

    Overloading new and its peers (new[], delete, and delete[]) is quite useful in restricting the way the object is created.

    For example,
    class OnlyStackAlloc
    {
    private:
    ...
  14. Re: Can Singleton GetInstance() function be inlined?

    Dear NMTOP40,

    Thankyou for your response.

    Finally, you got it correct. Keep it up.

    Thanking you,

  15. Re: Can Singleton GetInstance() function be inlined?

    Dear exterminator,
    Thread-safety w.r.to initialization here is not defined in terms of number of times an object is initialized, but in terms of "whether the object is properly initialized by one...
  16. Re: Can Singleton GetInstance() function be inlined?

    Dear SuperKoko,
    Do not worry about the situation of invoking the constructor after assignment. Compilers are not that dumb --- they have clearly specified rules for them, Construction of object is a...
  17. Re: Can Singleton GetInstance() function be inlined?

    Dear NMTOP40,

    Thankyou for your reponse. As for your question

    May be you want to answer it yourself --- afterall it was your own singleton counter code that I have modified to show you how...
  18. Re: Can Singleton GetInstance() function be inlined?

    Dear Mr.venkyhyd,

    The code you have presented involves: static Class1 *UniqueObject;

    So you are using a native pointer type as a static varible, and hence its initialization does not involve...
  19. Re: Can Singleton GetInstance() function be inlined?

    Dear SuperKoko,

    There are dozens of "theoritically correct" singleton designs out there.

    But if you have not forgotten, the issue of this thread is more about the "efficiency factor" ---...

  23. Re: Can Singleton GetInstance() function be inlined?

    Dear NMTop40,

    Yes it is a singleton counter.

    The address tests of Mr.venkyhyd also confirm this.

    But, as pointed out by Mr.SuperKoko, due to the hidden boolen variable involved in...
  24. Re: Can Singleton GetInstance() function be inlined?

    Dear SuperKoko,

    Thankyou for the thorough and complete explanation again.

    You touched the real critical point: "Generally, compilers produce non thread-safe test code for the boolean flag! "...
  25. Re: Can Singleton GetInstance() function be inlined?

    Dear venkyhyd,

    Thankyou for brining the class - integer type difference to my attention. Now that you have mentioned it, I could see more clearly the purpose of your second code and it seems you...
