Method calls on the proxy are translated into method calls on the remote object. :Parameters: `bus_name` : str A bus name (either the unique name or a well-known name) of the application owning the object. The keyword argument named_service is a deprecated alias for this. `object_path` : str The object path of the desired object `introspect` : bool If true (default), attempt to introspect the remote object to find out supported methods and their signatures `follow_name_owner_changes` : bool If the object path is a well-known name and this parameter is false (default), resolve the well-known name to the unique name of its current owner and bind to that instead; if the ownership of the well-known name changes in future, keep communicating with the original owner. This is necessary if the D-Bus API used is stateful. If the object path is a well-known name and this parameter is true, whenever the well-known name changes ownership in future, bind to the new owner, if any. If the given object path is a unique name, this parameter has no effect. :Returns: a `dbus.proxies.ProxyObject` :Raises `DBusException`: if resolving the well-known name to a unique name fails rG NrH r rI ziPassing the named_service parameter to get_object by name is deprecated: please use positional parametersrK rL z4get_object does not take these keyword arguments: %sz, )� introspect�follow_name_owner_changes) Z_require_main_looprR rS rT rJ rU �join�keysZProxyObjectClass)r8 r1 Z object_pathrb rc �kwargsrG rJ r" r" r% � get_object� s& $ � � �zBusConnection.get_objectc C s t |� | �tttdd|f�S )z�Get the numeric uid of the process owning the given bus name. :Parameters: `bus_name` : str A bus name, either unique or well-known :Returns: a `dbus.UInt32` :Since: 0.80.0 ZGetConnectionUnixUserr5 �r � call_blockingr r r �r8 r1 r" r" r% � get_unix_user� s �zBusConnection.get_unix_userr c C s$ t |� d| �tttdd||f�fS )a?
