public class NumberCharSequenceNormalizer
extends Object
implements opennlp.tools.util.normalizer.CharSequenceNormalizer

A CharSequenceNormalizer implementation that normalizes text in terms of numbers: every maximal run of ASCII digits (0 to 9), that is the longest unbroken stretch of consecutive digits, is replaced by a single space. For example, "a1234b56" becomes "a b ". Non-ASCII digits, for example Arabic-Indic or fullwidth digits, are not treated as digits and are left unchanged.
