This class reconstructs objects from an archive.
Re-using the archiver
The -resetUnarchiverWithData:atIndex: method lets you re-use the archive to decode a new data object or, in conjunction with the 'cursor' method (which reports the current decoding position in the archive), decode a second archive that exists in the data object after the first one.
Subclassing with different input format.
NSUnarchiver normally reads directly from an
NSData object using the methods -
And uses other NSData methods to read the archive header information from within the method: [-deserializeHeaderAt:version:classes:objects:pointers:] to read a fixed size header including archiver version (obtained by [self systemVersion]) and crossreference table sizes.
To subclass NSUnarchiver, you must implement your own
versions of the four methods above, and override
the 'directDataAccess' method to return NO
so that the archiver knows to use your serialization
methods rather than those in the NSData object.
