 23   
  * This implementation allows to pack some FileEntryParsers together
 24   
  * and handle the case where to returned dirstyle isnt clearly defined.
 25   
  * The matching parser will be cached.
 26   
  * If the cached parser wont match due to the server changed the dirstyle,
 27   
  * a new matching parser will be searched.
