所有已实现的接口:

Serializable

public class DescriptiveStatisticsHistogramStatistics
extends org.apache.flink.metrics.HistogramStatistics
implements Serializable

DescriptiveStatistics histogram statistics implementation returned by DescriptiveStatisticsHistogram.

The statistics takes a point-in-time snapshot of a DescriptiveStatistics instance and allows optimised metrics retrieval from this.
