public class PrimitiveParDoSingleFactory<InputT,OutputT>
extends org.apache.beam.runners.core.construction.SingleInputOutputOverrideFactory<PCollection<? extends InputT>,PCollection<OutputT>,ParDo.SingleOutput<InputT,OutputT>>

A PTransformOverrideFactory that produces PrimitiveParDoSingleFactory.ParDoSingle instances from ParDo.SingleOutput instances. PrimitiveParDoSingleFactory.ParDoSingle is a primitive PTransform, to ensure that RunnerApi.DisplayData appears on all ParDos in the DataflowRunner.
