Class RangedClassifier

Object

Classifier

RangedClassifier

public final class RangedClassifier
extends Classifier

Classifies into ranges of minimum and maximum values.

The buckets are defined such that:
min <= x < max

So if you provide the following min/max values:
min = {3, 6, 9}
max = {4, 10, 30}

The classify function will classify items based on:
3 <= x < 4
6 <= x < 10
9 <= x <= 30
