### Question:
LongLastValueAggregator extends AbstractAggregator { @Override @Nullable public Point toPoint(long startEpochNanos, long epochNanos, Labels labels) { @Nullable Long currentValue = current.get(); return currentValue == null ? null : LongPoint.create(startEpochNanos, epochNanos, labels, current.get()); }  static AggregatorFactory getFactory(); @Override @Nullable Point toPoint(long startEpochNanos, long epochNanos, Labels labels); @Override void doRecordLong(long value);  }### Answer:
@Test void toPoint() { Aggregator aggregator = LongLastValueAggregator.getFactory().getAggregator(); assertNullPoint(aggregator); }
