.SH "Detailed Description"
.PP 
\fBA\fP way of extending a NSCoder to enable the setting of MTLDevice for unarchived objects  When a object is initialized by a NSCoder, it calls -initWithCoder:, which is missing the necessary MTLDevice to correctly initialize the \fBMPSKernel\fP, or \fBMPSNNGraph\fP\&. If the coder does not conform to \fBMPSDeviceProvider\fP, the system default device will be used\&. If you would like to specify which device to use, subclass the NSCoder (NSKeyedUnarchiver, etc\&.) to conform to \fBMPSDeviceProvider\fP so that the device can be gotten from the NSCoder\&.
.PP
See \fBMPSKeyedUnarchiver\fP for one implementation of this protocol\&. It reads files prepared with the NSKeyedArchiver and allows you to set the MTLDevice that the unarchived objects use\&.
