Detailed Description

Command group handler class.

Objects of the handler class collect information about command group, such as kernel, requirements to the memory, arguments for the kernel.

sycl::queue::submit([](handler &CGH){
  CGH.require(Accessor1);   // Adds a requirement to the memory object.
  CGH.setArg(0, Accessor2); // Registers accessor given as an argument to
                            // the kernel + adds a requirement to the memory
                            // object.
  CGH.setArg(1, N);         // Registers value given as an argument to the
                            // kernel.
  // The following registers KernelFunctor to be a kernel that will be
  // executed in case of queue is bound to the host device, Kernel - for
  // an OpenCL device. This function clearly indicates that command group
  // represents kernel execution.
  CGH.parallel_for(KernelFunctor, Kernel);
 });

The command group can represent absolutely different operations. Depending on the operation we need to store different data. But, in most cases, it's impossible to say what kind of operation we need to perform until the very end. So, handler class contains all fields simultaneously, then during "finalization" it constructs CG object, that represents specific operation, passing fields that are required only.

inline

Implements parallel_for() accepting nd_range Range and one reduction object.
