| Initial Java implementation by <code>William B. Brogden. December, 1997</code>. |
| Permission given by <code>wbrogden</code> for code to be used anywhere. |
| <p> |
| <code>Hanging on the Metaphone</code> by <code>Lawrence Philips</code> in <code>Computer Language of Dec. 1990, |
| p 39.</code> |
| <p> |
| Note, that this does not match the algorithm that ships with PHP, or the algorithm found in the Perl implementations: |

| This class is conditionally thread-safe. |
| The instance field <span class="xref">Lucene.Net.Analysis.Phonetic.Language.Metaphone.maxCodeLen</span> is mutable <a class="xref" href="Lucene.Net.Analysis.Phonetic.Language.Metaphone.html#Lucene_Net_Analysis_Phonetic_Language_Metaphone_MaxCodeLen">MaxCodeLen</a> |
| but is not volatile, and accesses are not synchronized. |
| If an instance of the class is shared between threads, the caller needs to ensure that suitable synchronization |
| is used to ensure safe publication of the value between threads, and must not set <a class="xref" href="Lucene.Net.Analysis.Phonetic.Language.Metaphone.html#Lucene_Net_Analysis_Phonetic_Language_Metaphone_MaxCodeLen">MaxCodeLen</a> |
