Class CollatorComparator

  • All Implemented Interfaces:
    Direct Known Subclasses:

    public class CollatorComparator
    extends java.lang.Object
    implements java.util.Comparator<java.lang.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>.
