DescriptiveStatisticsHistogramStatistics (Flink : Runtime 2.0.0 API)

java.lang.Object
- org.apache.flink.metrics.HistogramStatistics
- - org.apache.flink.runtime.metrics.DescriptiveStatisticsHistogramStatistics

All Implemented Interfaces:

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.
