Its positional arguments will be the arguments of the signal. By default it will receive no keyword arguments, but see the description of the optional keyword arguments below. `signal_name` : str The signal name; None (the default) matches all names `dbus_interface` : str The D-Bus interface name with which to qualify the signal; None (the default) matches all interface names `bus_name` : str A bus name for the sender, which will be resolved to a unique name if it is not already; None (the default) matches any sender. `path` : str The object path of the object which must have emitted the signal; None (the default) matches any object path :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). `named_service` : str A deprecated alias for `bus_name`. rNrrrzrPassing the named_service parameter to add_signal_receiver by name is deprecated: please use positional parametersrr) Z_require_main_loopr5r6rrrrrzacquirerx setdefaultrQrelease) r:Zhandler_function signal_namer>r}pathkeywordsrrmatch by_interface by_membermatchesrrradd_signal_receiverKs4G         zConnection.add_signal_receiverc cs|dur d|f}nd}|durd|f}nd}|dur d|f}nd}|D]5}|j|}|dur1q$|D]%}||d}|dur@q3|D]}||d} | durOqB| D]} | VqQqBq3q$dS)Nr)rxget) r:rr>r?Z path_keysZinterface_keysZ member_keysrrrmrrr_iter_easy_matchess8      zConnection._iter_easy_matchescKsb|dd}|dur!|durtd|}ddlm}|dtddg} g} |jzt|j|d} | dur>W|j dS| |d} | durPW|j dS| |d} | durbW|j dS| D]}||usw|j |||||fi|r}| |qd| |qd| r| | |<n| |=| s| |=| s|j|=W|j n|j w| D]}| |qdS)NrrrrzuPassing the named_service parameter to remove_signal_receiver by name is deprecated: please use positional parametersrr) r5r6rrrrzrrxrrrZrQ_clean_up_signal_match)r:Zhandler_or_matchrr>r}rrrrnewZ deletionsrrrrrrrrlsh         z!Connection.remove_signal_receivercCrrr)r:rrrrrsz!Connection._clean_up_signal_matchc Cst|tstS|}|}|}||||D]}||q|tkrN|t krN|dkrN|j D]}z||Wq1t yMt tjdddYq1wtS)zvD-Bus filter function.
