<h3 class="section">8.1 GNU Objective-C Runtime API</h3>
|
||
|
|
|
||
|
|
<p>This section is specific for the GNU Objective-C runtime. If you are
|
||
|
|
using a different runtime, you can skip it.
|
||
|
|
</p>
|
||
|
|
<p>The GNU Objective-C runtime provides an API that allows you to
|
||
|
|
interact with the Objective-C runtime system, querying the live
|
||
|
|
runtime structures and even manipulating them. This allows you for
|
||
|
|
example to inspect and navigate classes, methods and protocols; to
|
||
|
|
define new classes or new methods, and even to modify existing classes
|
||
|
|
or protocols.
|
||
|
|
</p>
|
||
|
|
<p>If you are using a “Foundation” library such as GNUstep-Base, this
|
||
|
|
library will provide you with a rich set of functionality to do most
|
||
|
|
of the inspection tasks, and you probably will only need direct access
|
||
|
|
to the GNU Objective-C runtime API to define new classes or methods.
|
||
|
|
