Class RefinedSoundex

java.lang.Object

org.apache.commons.codec.language.RefinedSoundex

All Implemented Interfaces:

Encoder, StringEncoder

Deprecated.

Please use URL.openConnection() instead. Please visit this webpage for further details.

@Deprecated
public class RefinedSoundex
extends java.lang.Object
implements StringEncoder

Encodes a string into a Refined Soundex value. A refined soundex code is optimized for spell checking words. Soundex method originally developed by Margaret Odell and Robert Russell.

Field Detail

US_ENGLISH

public static final RefinedSoundex US_ENGLISH

Deprecated.

This static variable contains an instance of the RefinedSoundex using the US_ENGLISH mapping.

US_ENGLISH_MAPPING

public static final char[] US_ENGLISH_MAPPING

Deprecated.

RefinedSoundex is *refined* for a number of reasons one being that the mappings have been altered. This implementation contains default mappings for US English.

Constructor Detail

RefinedSoundex

public RefinedSoundex()

Deprecated.

Creates an instance of the RefinedSoundex object using the default US English mapping.

RefinedSoundex

public RefinedSoundex(char[] mapping)

Deprecated.

Creates a refined soundex instance using a custom mapping. This constructor can be used to customize the mapping, and/or possibly provide an internationalized mapping for a non-Western character set.

Parameters:

mapping - Mapping array to use when finding the corresponding code for a given character

Method Detail

difference

public int difference(java.lang.String s1,
                      java.lang.String s2)
               throws EncoderException

Deprecated.

Returns the number of characters in the two encoded Strings that are the same. This return value ranges from 0 to the length of the shortest encoded String: 0 indicates little or no similarity, and 4 out of 4 (for example) indicates strong similarity or identical values. For refined Soundex, the return value can be greater than 4.

Parameters:

s1 - A String that will be encoded and compared.

s2 - A String that will be encoded and compared.

Returns:

The number of characters in the two encoded Strings that are the same from 0 to to the length of the shortest encoded String.

Throws:

EncoderException - if an error occurs encoding one of the strings

Since:

1.3

encode

public java.lang.Object encode(java.lang.Object pObject)
                        throws EncoderException

Deprecated.

Encodes an Object using the refined soundex algorithm. This method is provided in order to satisfy the requirements of the Encoder interface, and will throw an EncoderException if the supplied object is not of type java.lang.String.

Specified by:

encode in interface Encoder

Parameters:

pObject - Object to encode

Returns:

An object (or type java.lang.String) containing the refined soundex code which corresponds to the String supplied.

Throws:

EncoderException - if the parameter supplied is not of type java.lang.String

encode

public java.lang.String encode(java.lang.String pString)

Deprecated.

Encodes a String using the refined soundex algorithm.

Specified by:

encode in interface StringEncoder

Parameters:

pString - A String object to encode

Returns:

A Soundex code corresponding to the String supplied

soundex

public java.lang.String soundex(java.lang.String str)

Deprecated.

Retreives the Refined Soundex code for a given String object.

Parameters:

str - String to encode using the Refined Soundex algorithm

Returns:

A soundex code for the String supplied
