@Override

  final JavaRDD<?> input = context.getSingleInput(operator);
  final UnaryFunctor<?, ?> mapper = operator.getFunctor();
  final ExtractEventTime<?> evtTimeFn = operator.getEventTimeExtractor();

  LazyAccumulatorProvider accumulators =
    new LazyAccumulatorProvider(context.getAccumulatorFactory(), context.getSettings());
  if (evtTimeFn != null) {
   return input
     .flatMap(new EventTimeAssigningUnaryFunctor(mapper, evtTimeFn, accumulators))
     .setName(operator.getName() + "::event-time-and-apply-udf");
  } else {
   return input
     .flatMap(new UnaryFunctorWrapper(mapper, accumulators))
     .setName(operator.getName() + "::apply-udf");
  }
 }
