Question

Is it possible to prevent stack allocation of an object and only allow it to be instiated with ‘new’ on the heap?

Answer 1

One way you could do this would be to make the constructors private and only allow construction through a static method that returns a pointer. For example:

class Foo { public:     ~Foo();     static Foo* createFoo()     {         return new Foo();     } private:     Foo();     Foo(const Foo&);     Foo& operator=(const Foo&); };
