public static interface Fields.UpdateCallback

An UpdateCallback is a callback provided to calls that potentially update buckets. It is a single method interface that can provide feedback to the caller about when a bucket was updated. This enables the HipHllSketch to get the information it needs to use the HipEstimation algorithm instead of the built-in one.
