When instantiated, objects of this class attempt to claim the given well-known name on the given bus for the current process. The name is released when the BusName object becomes unreferenced. If a well-known name is requested multiple times, multiple references to the same BusName object will be returned. Caveats ------- - Assumes that named services are only ever requested using this class - if you request names from the bus directly, confusion may occur. - Does not handle queueing. c C sS t | d t d t �| d k rP d d l } | j d t d d �t � } n | | j k rj | j | S| ry t j p| d | r� t j p� d B| r� t j p� d B} | j | | � } | t j k r� nX | t j k r� nF | t j k r� t | � � n( | t j k r n t d | | f � � t j | � } | | _ | | _ | | j | <| S( sS Constructor, which may either return an existing cached object or a new object. :Parameters: `name` : str The well-known name to be advertised `bus` : dbus.Bus A Bus on which this service will be advertised.
