   9       * Identifies the right kind of url, based on the format of our links. This class is only taken
  10       * into use when custom urls are enabled, and it basically loops through all provided regular expressions
  11       * and a given HTTP request to check which one of them is the matching one. The matching engine (converting
  12       * from *_link_format format to a valid regexp) is provided by the LinkParser class.
  13       *
  14       * Once ready, it will call the LinkFormatMatcher::getParameters() to retrieve the right parameters
  15       * for the request (the core does not understand this kind of requests, and this class acts as some sort
  16       * of a filter that parses an incoming nicer link, gets the information based on a regexp and puts it back to
  17       * the request in a more "normal" format)
  18       *
  19       * Users or plugin developers should never need to use this class directly.
