Class AlphanumericComparator

java.lang.Object

com.docdoku.core.util.AlphanumericComparator

All Implemented Interfaces:

Comparator<CharSequence>

public class AlphanumericComparator
extends Object
implements Comparator<CharSequence>

Comparator for ordering by Collator while treating digits numerically. This provides a "natural" order that humans usually perceive as 'logical'. It should work reasonably well for western languages (provided you use the proper collator when constructing). For free control over the Collator, use the constructor that takes a Collator as parameter. Configure the Collator using Collator.setDecomposition()/setStrength() to suit your requirements.
