@Shareable public class ValueArrayQuantizer extends java.lang.Object implements Quantizer, java.io.Serializable
Abstract quantizer implementation using a pre-generated array of possible values. Values are quantized to their closest discrete possibility.

Quantizer
Get the possible values into which this quantizer will map input values. These are the values corresponding to each “bin” into which the quantizer will put values.
