This protocol declares an interface is adopted by classes to provide
for archiving and
unarchiving of instances of the class. The
NSCoding protocol defines the two methods
initWithCode: and
encodeWithCode:. These two methods are the
foundation of archiving and distribution in the Foundation framework.
Each of these two methods passes an NSCoder
object, which is used to perform archiving and unarchiving. The
NSCoder class provides the tools to encode and
decode objects and C and Objective-C data types. See the
NSCoder class description and Chapter 2 for more information.
