cuda::experimental::stf::stream_reduction_operator_untyped

class stream_reduction_operator_untyped : public cuda::experimental::stf::reduction_operator_base

Helper class to define a reduction operator attached to a data interface.

Defining a new operator requires to define the virtual methods stream_init_op and stream_redux_op which respectively initialize a data instance, and apply the reduction operator over two instances.

See stream_reduction_operator for a class which directly manipulates typed data instances, with a simpler programming interface.
