(Read-only, may change.) If the proxy was instantiated using a unique name, this property is that unique name. If the proxy was instantiated with a well-known name and with ``follow_name_owner_changes`` set false (the default), this property is the unique name of the connection that owned that well-known name when the proxy was instantiated, which might not actually own the requested well-known name any more.

Its positional arguments will be the arguments of the signal; optionally, it may be given keyword arguments as described below. `dbus_interface` : str Optional interface with which to qualify the signal name. If None (the default) the handler will be called whenever a signal of the given member name is received, whatever its interface. :Keywords: `utf8_strings` : bool If True, the handler function will receive any string arguments as dbus.UTF8String objects (a subclass of str guaranteed to be UTF-8). If False (default) it will receive any string arguments as dbus.String objects (a subclass of unicode). `byte_arrays` : bool If True, the handler function will receive any byte-array arguments as dbus.ByteArray objects (a subclass of str). If False (default) it will receive any byte-array arguments as a dbus.Array of dbus.Byte (subclasses of: a list of ints). `sender_keyword` : str If not None (the default), the handler function will receive the unique name of the sending endpoint as a keyword argument with this name `destination_keyword` : str If not None (the default), the handler function will receive the bus name of the destination (or None if the signal is a broadcast, as is usual) as a keyword argument with this name. `interface_keyword` : str If not None (the default), the handler function will receive the signal interface as a keyword argument with this name. `member_keyword` : str If not None (the default), the handler function will receive the signal name as a keyword argument with this name. `path_keyword` : str If not None (the default), the handler function will receive the object-path of the sending object as a keyword argument with this name `message_keyword` : str If not None (the default), the handler function will receive the `dbus.lowlevel.SignalMessage` as a keyword argument with this name. `arg...` : unicode or UTF-8 str If there are additional keyword parameters of the form ``arg``\ *n*, match only signals where the *n*\ th argument is the value given for that keyword parameter.

The returned proxy method can be called in the usual way. For instance, :: proxy.get_dbus_method("Foo", dbus_interface='com.example.Bar')(123) is equivalent to:: proxy.Foo(123, dbus_interface='com.example.Bar') or even:: getattr(proxy, "Foo")(123, dbus_interface='com.example.Bar') However, using `get_dbus_method` is the only way to call D-Bus methods with certain awkward names - if the author of a service implements a method called ``connect_to_signal`` or even ``__getattr__``, you'll need to use `get_dbus_method` to call them. For services which follow the D-Bus convention of CamelCaseMethodNames this won't be a problem. ) �ProxyMethodClassrN r- rR rX rY �DeferredMethodClassr} r{ )r r� r; �retr r r r� � s � �zProxyObject.get_dbus_methodc C s d| j | j| jt| �f S )Nz&<ProxyObject wrapping %s %s %s at %#x>)rN r- rR �idr` r r r �__repr__� s �zProxyObject.__repr__)NNNTFr )r& r' r( r) r* r� r r� rW rY rr r �propertyr5 �requested_bus_namer6 rh rZ ro rm rn r{ r} r� r� r� �__str__r r r r rB � s@ � S��� C &rB c @ s� e Zd ZdZdd� Zedd� ddd�ZeZedd� ddd �Zed d� ddd �Z ed d� ddd �Z edd� ddd�Z ddd�Z dd� Z ddd�Zdd� ZeZdS )� Interfacez�An interface into a remote object.
