com.linkedin.alpini.base.statistics.LongStatsArrayAggregator

All Implemented Interfaces:

java.util.function.LongConsumer

public class LongStatsArrayAggregator
extends LongStatsAggregator

Extend the LongQuantileEstimation class and add computation for the mean and standard deviation of the supplied values. The statistics are summarised in a LongStats object and the statistics are reset.
