Detailed Description

Unarchives objects created using CPKeyedArchiver.

CPKeyedUnarchiver is used for creating objects out of coded files or CPData objects that were created by CPKeyedArchiver. More specifically, this class unarchives objects from a data stream or file and brings them back into memory for programmatic usage.

-(Class)unarchiver:(CPKeyedUnarchiver)unarchiver cannotDecodeObjectOfClassName:(CPString)name originalClasses:(CPArray)classNames; Called when the specified class is not available during decoding. The delegate may load the class, or return a substitute class to use instead.

Parameters:

unarchiver	the unarchiver performing the decode
name	the name of the class that can't be found
an	array of class names describing the encoded object's class hierarchy. The first index is the encoded class name, and each superclass is after that.

Returns:

the Class to use instead or nil to abort the unarchiving operation

-(id)unarchiver:(CPKeyedUnarchiver)unarchiver didDecodeObject:(id)object; Called when the unarchiver decodes an object.

Parameters:

unarchiver	the unarchiver doing the decoding
object	the decoded object

Returns:

a substitute to use for the decoded object. This can be the same object argument provide, another object or nil.

-(void)unarchiver:(CPKeyedUnarchiver)unarchiver willReplaceObject:(id)object withObject:(id)newObject; Called when a decoded object has been substituted with another. (for example, from -unarchiver:didDecodeObject:.

Parameters:

unarchiver	the unarchiver that decoded the object
object	the original decoded object
newObject	the replacement object

-(void)unarchiverWillFinish:(CPKeyedUnarchiver)unarchiver; Called when the unarchiver is about to finish decoding.

Parameters:

unarchiver

the unarchiver that's about to finish

-(void)unarchiverDidFinish:(CPKeyedUnarchiver)unarchiver; Called when the unarchiver has finished decoding.

Parameters:

unarchiver

the unarchiver that finished decoding

Method Documentation

- (BOOL) allowsKeyedCoding

Returns a flag indicating whether the receiver supports keyed coding. The default implementation returns NO. Subclasses supporting keyed coding must override this to return YES.

Reimplemented from CPCoder.
