Class ExponentialHistogramStates.WithLongGroupingState

java.lang.Object

org.elasticsearch.compute.aggregation.ExponentialHistogramStates.WithLongGroupingState

All Implemented Interfaces:

Closeable, AutoCloseable, GroupingAggregatorState, org.elasticsearch.core.Releasable

Enclosing class:

ExponentialHistogramStates

public static final class ExponentialHistogramStates.WithLongGroupingState
extends Object
implements GroupingAggregatorState

A grouping state consisting of a single long value with a ExponentialHistogram per group. The intermediate state contains three values in order: the long, the histogram, and a boolean specifying if a value was set or not.
