Direct Known Subclasses:

LocaleComparator

public class CollatorComparator
extends Object
implements Comparator<String>

A comparator that sorts Strings using a Collator. This class is needed because, even though Collator implements Comparator<Object> and the required compare(String, String) method, you can't safely cast Collator to Comparator<String>.
