 private void closeWindow(
     K key, W w, Map<W, AccumT> accumulators, Map<W, Instant> minTimestamps, ProcessContext c) {
   AccumT accum = accumulators.remove(w);
   Instant timestamp = minTimestamps.remove(w);
   checkState(accum != null && timestamp != null);
   c.windowingInternals()
       .outputWindowedValue(
           KV.of(key, combineFn.extractOutput(key, accum)),
           timestamp,
           Arrays.asList(w),
           PaneInfo.ON_TIME_AND_ONLY_FIRING);
 }
