This is the only class - * a user needs to use to perform Yadis discovery. This class - * performs the discovery AND stores the result of the discovery. - * - * First, require this library into your program source: - * - * 
  require_once "Auth/Yadis/Yadis.php";
- * - * To perform Yadis discovery, first call the "discover" method - * statically with a URI parameter: - * - * 
  $http_response = array();
- *  $fetcher = Auth_Yadis_Yadis::getHTTPFetcher();
- *  $yadis_object = Auth_Yadis_Yadis::discover($uri,
- *                                    $http_response, $fetcher);
- * - * If the discovery succeeds, $yadis_object will be an instance of - * {@link Auth_Yadis_Yadis}. If not, it will be null. The XRDS - * document found during discovery should have service descriptions, - * which can be accessed by calling - * - * 
  $service_list = $yadis_object->services();
- * - * which returns an array of objects which describe each service. - * These objects are instances of Auth_Yadis_Service. Each object - * describes exactly one whole Service element, complete with all of - * its Types and URIs (no expansion is performed). The common use - * case for using the service objects returned by services() is to - * write one or more filter functions and pass those to services(): - * - * 
  $service_list = $yadis_object->services(
- *                               array("filterByURI",
- *                                     "filterByExtension"));
- * - * The filter functions (whose names appear in the array passed to - * services()) take the following form: - * - * 
  function myFilter(&$service) {
- *       // Query $service object here.  Return true if the service
- *       // matches your query; false if not.
- *  }
- * - * This is an example of a filter which uses a regular expression to - * match the content of URI tags (note that the Auth_Yadis_Service - * class provides a getURIs() method which you should use instead of - * this contrived example): - * - * 
- *  function URIMatcher(&$service) {
- *      foreach ($service->getElements('xrd:URI') as $uri) {
- *          if (preg_match("/some_pattern/",
- *                         $service->parser->content($uri))) {
- *              return true;
- *          }
- *      }
- *      return false;
- *  }
- * - * The filter functions you pass will be called for each service - * object to determine which ones match the criteria your filters - * specify. The default behavior is that if a given service object - * matches ANY of the filters specified in the services() call, it - * will be returned. You can specify that a given service object will - * be returned ONLY if it matches ALL specified filters by changing - * the match mode of services(): - * - * 
  $yadis_object->services(array("filter1", "filter2"),
- *                          SERVICES_YADIS_MATCH_ALL);
- * - * See {@link SERVICES_YADIS_MATCH_ALL} and {@link - * SERVICES_YADIS_MATCH_ANY}. - * - * Services described in an XRDS should have a library which you'll - * probably be using. Those libraries are responsible for defining - * filters that can be used with the "services()" call. If you need - * to write your own filter, see the documentation for {@link - * Auth_Yadis_Service}. - * - * @package OpenID - */ -class Auth_Yadis_Yadis { - - /** - * Returns an HTTP fetcher object.
