org.apache.commons.codec.language.AbstractCaverphone

All Implemented Interfaces:

Encoder, StringEncoder

Direct Known Subclasses:

Caverphone1, Caverphone2

public abstract class AbstractCaverphone
extends java.lang.Object
implements StringEncoder

Encodes a string into a Caverphone value. This is an algorithm created by the Caversham Project at the University of Otago. It implements the Caverphone 2.0 algorithm:

This class is immutable and thread-safe.

Method Detail

encode

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

Encodes an Object using the caverphone 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:

source - Object to encode

Returns:

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

Throws:

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

isEncodeEqual

public boolean isEncodeEqual(java.lang.String str1,
                             java.lang.String str2)
                      throws EncoderException

Tests if the encodings of two strings are equal. This method might be promoted to a new AbstractStringEncoder superclass.

Parameters:

str1 - First of two strings to compare

str2 - Second of two strings to compare

Returns:

true if the encodings of these strings are identical, false otherwise.

Throws:

EncoderException - thrown if there is an error condition during the encoding process.
