Cocoa in a Nutshell

Name

NSCoder — Mac OS X 10.0

Synopsis

This class defines an abstract interface for subclasses that implement object archival functionality. The Foundation framework implements five concreate subclasses: NSArchiver and NSUnarchiver are used for non-keyed archiving, while NSKeyedArchiver and NSKeyedUnarchiver provide support for keyed-archiving. NSPortCoder is used by the distributed objects system to send object proxies across a connection. For more information, see the class references for these five classes, the protocol reference for the NSCoding protocol, and Chapter 2.
