# Class NumberCharSequenceNormalizer

java.lang.Object
opennlp.tools.util.normalizer.NumberCharSequenceNormalizer

All Implemented Interfaces:
  `Serializable`, `opennlp.tools.util.normalizer.CharSequenceNormalizer`

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.
