public class HllSketchIsLessThan
extends uk.gov.gchq.koryphe.predicate.KoryphePredicate<com.yahoo.sketches.hll.HllSketch>

An HllSketch is a Predicate that simply checks that the input HllSketch cardinality is less than a control value. Before applying the is less than check, it will round the HllSketch estimate to the nearest long.
