public class ColognePhonetic extends java.lang.Object implements StringEncoder
Implements the Kölner Phonetik (Cologne Phonetic) algorithm issued by Hans Joachim Postel in 1969.
The Kölner Phonetik is a phonetic algorithm which is optimized for the German language. It is related to the well-known soundex algorithm.

public java.lang.String colognePhonetic(java.lang.String text)
Implements the Kölner Phonetik algorithm.
In contrast to the initial description of the algorithm, this implementation does the encoding in one pass.
