Class specific new/delete

2018-06-26 02:35:42

Is it possible to overload class specific new/delete that is called when arrays of objects are created.

class Foo;

Foo* f = new Foo[10]; // calls overloaded new
delete[] f; // calls overloaded delete

Thank you.

Yes, it is possible. There is a tutorial about overloading new and delete here, and there is a nice example of overloading new and delete for array, here.

class Myclass
{
  public:
        void* operator new(size_t); 
        void operator delete(void*);

        void* operator new[](size_t); 
        void operator delete[](void*);
};
