Class StringEncoderComparator

java.lang.Object

edu.internet2.middleware.grouperClientExt.org.apache.commons.codec.StringEncoderComparator

All Implemented Interfaces:

Comparator

public class StringEncoderComparator
extends Object
implements Comparator

Strings are comparable, and this comparator allows you to configure it with an instance of a class which implements StringEncoder. This comparator is used to sort Strings by an encoding scheme such as Soundex, Metaphone, etc. This class can come in handy if one need to sort Strings by an encoded form of a name such as Soundex.
