(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. As of this time only string arguments can be matched (in particular, object paths and signatures can't). )� signal_namer4 r0 �path)rE Zadd_signal_receiverr+ rG �r rS Zhandler_functionr4 r r r r �connect_to_signal2 s < ���z ProxyObject.connect_to_signalc C s> i }t rd|d< | jj| j| jtddd| j| jfddi|��S )NTZ utf8_stringsZ Introspect� r Zrequire_main_loopF)r rE r" r+ rG r �_introspect_reply_handler�_introspect_error_handler)r rO r r r rN u s ���zProxyObject._Introspectc C s* | j D ]\}}}||i |�� qg | _ d S r )rI )r r r r r r r �_introspect_execute_queue� s z%ProxyObject._introspect_execute_queuec C s� | j �� zpzt|�| _W n< tyV } z$| �|� W Y d }~W | j �� d S d }~0 0 | j| _d | _ | � � W | j �� n | j �� 0 d S r ) rJ �acquirer r8 r rY �release� INTROSPECT_STATE_INTROSPECT_DONErL rH rZ )r �data�er r r rX � s � z%ProxyObject._introspect_reply_handlerc C sr t �� t�d| j| j|jj|jj|� | j � � z.t� d� | j | _ d | _| �� W | j �� n | j �� 0 d S )Nz$Introspect error on %s:%s: %s.%s: %sz'Executing introspect queue due to error)�loggingZ basicConfig�_logger�errorr+ rG � __class__r% r$ rJ r[ �debugrK rL rH rZ r\ )r rb r r r rY � s � z%ProxyObject._introspect_error_handlerc C s> | j �� z"| jd ur | j�� W | j �� n | j �� 0 d S r )rJ r[ rH r r\ rP r r r �_introspect_block� s z ProxyObject._introspect_blockc C sX | j �� z<| j| jkr,| j�|||f� n||i |�� W | j �� n | j �� 0 d S r )rJ r[ rL rM rI r r\ )r �callbackr rO r r r �_introspect_add_to_queue� s z$ProxyObject._introspect_add_to_queuec C s, |� d�r |�d�r t|��n | �|�S d S �N�__)� startswith�endswith�AttributeError�get_dbus_method�r �memberr r r � __getattr__� s zProxyObject.__getattr__c C s< | � | | j| j| j||�}| j| jkr8| �|| j| j�}|S )a, Return a proxy method representing the given D-Bus method. The returned proxy method can be called in the usual way. For instance, :: proxy.get_dbus_method("Foo", dbus_interface='com.example.Bar')(123) is equivalent to:: proxy.Foo(123, dbus_interface='com.example.Bar') or even:: getattr(proxy, "Foo")(123, dbus_interface='com.example.Bar') However, using `get_dbus_method` is the only way to call D-Bus methods with certain awkward names - if the author of a service implements a method called ``connect_to_signal`` or even ``__getattr__``, you'll need to use `get_dbus_method` to call them. For services which follow the D-Bus convention of CamelCaseMethodNames this won't be a problem. ) �ProxyMethodClassrE r+ rG rL rM �DeferredMethodClassrg re )r ro r4 �retr r r rm � s � �zProxyObject.get_dbus_methodc C s d| j | j| jt| �f S )Nz&<ProxyObject wrapping %s %s %s at %#x>)rE r+ rG �idrP r r r �__repr__� s �zProxyObject.__repr__)NNNTF)N)N)r$ r% r& r' r( rq r rr rK rM r] r �propertyr0 �requested_bus_namer1 rV rN rZ rX rY re rg rp rm ru �__str__r r r r r: � s> � S ��� C &r: 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.
