Class StringEncoderComparator

java.lang.Object

com.epam.reportportal.apache.commons.codec.StringEncoderComparator

All Implemented Interfaces:

java.util.Comparator

public class StringEncoderComparator
extends java.lang.Object
implements java.util.Comparator

Compares Strings using a 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.

This class is immutable and thread-safe.

Method Detail

compare

public int compare(java.lang.Object o1,
                   java.lang.Object o2)

Specified by:

compare in interface java.util.Comparator

Parameters:

o1 - the object to compare

o2 - the object to compare to

Returns:

the Comparable.compareTo() return code or 0 if an encoding error was caught.
