Helper template class to manage releasable object pointers safely. When releasable object is assigned, its Release() method will be called at proper time. Can be used as follows.
ReleasablePtr<CReleasableObject> obj{ new CReleasableObject() };
// ...
// You may access CReleasableObject properties as methods in the usual way when you work with CReleasableObject pointer: obj->method()
// ...
// Instance of CReleasableObject stored in obj will be automatically released when obj is destroyed
You can find more information in comments below. Overrided methods can be found in corresponding base interface.
// TReleasable should be derived from IReleasable
template<class TReleasable>
class ReleasablePtr
{
public:
ReleasablePtr(); // Create without releasable object attached
ReleasablePtr(TReleasable *releasable); // Create with specified releasable object attached
ReleasablePtr(const ReleasablePtr &other); // Copy constructor
ReleasablePtr(ReleasablePtr &&other); // Move constructor
~ReleasablePtr(); // Destructor
ReleasablePtr &operator=(const ReleasablePtr &other); // Copy assignment operator
ReleasablePtr &operator=(ReleasablePtr &&other); // Move assignment operator
ReleasablePtr &operator=(TReleasable *releasable); // Assign releasable object
TReleasable *operator->();
const TReleasable* operator->() const;
operator TReleasable*();
operator const TReleasable* () const;
TReleasable *move() // Return assigned releasable object and clear internal reference to it so it is not released during class instance destruction
