All Implemented Interfaces:

Closeable, AutoCloseable, GroupingAggregatorState, Releasable

Enclosing class:

ExponentialHistogramStates

public static final class ExponentialHistogramStates.SeenGroupingState
extends Object
implements GroupingAggregatorState

A grouping state consisting of a single ExponentialHistogram per group, without a sort key. The intermediate state contains two values in order: the histogram, and a boolean specifying if a value was set or not.
