I tried to make delete operator private for my class. Strangely it is
giving me error if I compile that code in VC++.NET. But it compiles
successfully on VC++6.o. Can anybody give me inputs about it. I wanted
that on my class delete should not work. Object pointer should be
deleted using my function only which is taking care of reference count
for particular class.
Thanx in advance for your inputs.
Please show what you tried that didn't work.
I tried following one:
class RefCountImpl
{
private:
//data members
protected:
void operator delete(void*);
public:
//methods};
if i have above class implementation.Then in VC++6.0 it works. You can
allocate memory using new but you cannot delete that pointer in your
clilent code. You have to use some method provided by above class to
release the pointer.
Same thing doesnt work in VC++.NET. It clearly throws error that
making delete private cause memory leakage. May be VC++.NET compiler
become more stirct about this. :(.....
The problem is that the new operator must call delete if the
constructor throws. So you can't use new outside of a member
function if operator delete is private. Since this behavior was
added during standardization, some older compilers (e.g. VC++
6.0) might not implement it.
The solution, of course, is to provide factory functions as
well: static member functions which do the new.
