                                                 @NotNull java.lang.Object device)
        Description copied from class: MPSKernel
        NSSecureCoding compatability While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly. To avoid that problem, use initWithCoder:device instead.
        Overrides:
        initWithCoderDevice in class MPSMatrixRandom
        Parameters:
        aDecoder - The NSCoder subclass with your serialized MPSKernel
        device - The MTLDevice on which to make the MPSKernel
        Returns:
        A new MPSKernel object, or nil if failure. API-Since: 11.0

      • initWithDevice

        public MPSMatrixRandomMTGP32 initWithDevice​(@NotNull
                                            @NotNull java.lang.Object device)
        initialize a MPSMatrixRandomMTGP32 filter to generate 32-bit unsigned integer values with an initial seed of 0.
        Overrides:
        initWithDevice in class MPSMatrixRandom
        Parameters:
        device - The device the filter will run on
        Returns:
        a pointer to the newly initialized object. This will fail, returning nil if the device is not supported. Devices must be MTLFeatureSet_iOS_GPUFamily2_v1 or later.

        initialize a MPSMatrixRandomMTGP32 filter using a default distribution.
        Parameters:
        device - The device the filter will run on
        destinationDataType - The data type of the result.
        seed - The seed to initialize the random number generators with.

        initialize a MPSMatrixRandomMTGP32 filter
        Parameters:
        device - The device the filter will run on
        destinationDataType - The data type of the result.
        seed - The seed to initialize the random number generators with.
        distributionDescriptor - A descriptor containing information about the distribution.

        public boolean _supportsSecureCoding()
        Description copied from interface: NSSecureCoding
        This property must return YES on all classes that allow secure coding. Subclasses of classes that adopt NSSecureCoding and override initWithCoder: must also override this method and return YES. The Secure Coding Guide should be consulted when writing methods that decode data.
