Description

The abstract class standard-objc-object provides the framework for subclasses to implement an Objective-C class. Subclasses are typically defined using define-objc-class, which allows the Objective-C class name to be specified. Instances of such a subclass have an associated Objective-C foreign object whose pointer can be retrieved using the objc-object-pointer accessor. The function objc-object-from-pointer can be used to obtain the object again from the Objective-C foreign pointer.

There are two ways that subclasses of standard-objc-object can be made:
