.SH "Detailed Description"
.PP 
This depends on Metal\&.framework\&.  The \fBMPSCNNDropoutGradientState\fP is used to hold the mask used by both \fBMPSCNNDropout\fP forward filter and \fBMPSCNNDropoutGradient\fP backward filter\&. The \fBMPSCNNDropout\fP forward filter populates the \fBMPSCNNDropoutGradientState\fP object and the \fBMPSCNNDropoutGradient\fP backward filter consumes the state object\&.
.PP
While the mask is stored internally, the mask data is accessible by the user for debugging purposes via an accessor method\&. 
.SH "Method Documentation"

.PP
Reimplemented from \fBMPSState\fP\&.
.SS "\- (nonnull NSData*) maskData "
Mask data accessor method\&. 
.PP
\fBReturns:\fP
.RS 4
An autoreleased NSData object, containing the mask data\&. The mask data is populated in the -encode call, thus the contents are undefined until you -encode the filter\&. Use for debugging purposes only\&.
.RE
.PP
In order to gaurantee that the mask data is correctly synchronized for CPU side access, it is the application's responsibility to call the [gradientState synchronizeOnCommandBuffer:] method before accessing the mask data\&.
