Archiving
From GNUstepWiki
Allowing objects to be archived
To permit an object to be archived (also known as serialisation) its class needs to implement the NSCoding protocol. This protocol exposes two methods: -encoderWithCoder and -initWithCoder:. By implementing these methods, your object can be serialised/deserialised as well as sent over GNUstep's Distributed objects mechanism.
See the reference manual for more details.
