/* The Object class is a very minimal root class included with the
|
|
runtime. It is used as superclass for the two classes included
|
|
with the runtime, Protocol and NXConstantString.
|
|
|
|
Because Objective-C allows multiple root classes, you can define
|
|
your own root class, different from Object.
|
|
|
|
In particular, a Foundation library (such as GNUstep Base) is
|
|
expected to provide its own root class (typically called NSObject),
|
|
fully integrated with the library's own high-level features. It is
|
|
expected that you should always use and interact with NSObject, and
|
|
mostly ignore Object. */
