◆ run()

void run	(	const Window &	window,
		cl::CommandQueue &	queue
	)

overridevirtual

Enqueue the OpenCL kernel to process the given window on the passed OpenCL command queue.

Note: The queue is not flushed by this method, and therefore the kernel will not have been executed by the time this method returns.

Parameters

[in]	window	Region on which to execute the kernel. (Must be a valid region of the window returned by window()).
[in,out]	queue	Command queue on which to enqueue the kernel.

Reimplemented from ICLKernel.
