A read-only proxy representing a Photos asset or collection object yet to be created by a change request.

You obtain object placeholders when you use change requests to create assets, collections, or collection lists. After the change request completes, you can use the object placeholder to fetch the newly created object. You can also use an object placeholder to make additional change requests involving the object to be created.
This is an abstract class. You can't create an instance, but you can get one from various plugin functions.
