java.lang.Objectorg.apache.commons.codec.language.Soundex
public class Soundex
Encodes a string into a Soundex value. Soundex is an encoding used to relate similar names, but can also be used as a general purpose scheme to find word with similar phonemes.
| Field Summary | |
|---|---|
static Soundex |
US_ENGLISH
An instance of Soundex using the US_ENGLISH_MAPPING mapping. |
static String |
US_ENGLISH_MAPPING_STRING
This is a default mapping of the 26 letters used in US English. |
| Constructor Summary | |
|---|---|
Soundex()
Creates an instance using US_ENGLISH_MAPPING |
|
Soundex(char[] mapping)
Creates a soundex instance using the given mapping. |
|
Soundex(String mapping)
Creates a refined soundex instance using a custom mapping. |
|
| Method Summary | |
|---|---|
int |
difference(String s1,
String s2)
Encodes the Strings and returns the number of characters in the two encoded Strings that are the same. |
Object |
encode(Object pObject)
Encodes an Object using the soundex algorithm. |
String |
encode(String pString)
Encodes a String using the soundex algorithm. |
int |
getMaxLength()
Deprecated. This feature is not needed since the encoding size must be constant. Will be removed in 2.0. |
void |
setMaxLength(int maxLength)
Deprecated. This feature is not needed since the encoding size must be constant. Will be removed in 2.0. |
String |
soundex(String str)
Retrieves the Soundex code for a given String object. |
