It will either return a tuple of returned data, or raise :exc:`.DBusErrorResponse`. The methods available are defined by the message generator you wrap. You can set a time limit on a call by passing ``_timeout=`` in the method call, or set a default when creating the proxy. The ``_timeout`` argument is not passed to the message generator. All timeouts are in seconds, and :exc:`TimeoutErrror` is raised if it expires before a reply arrives. :param msggen: A message generator object :param ~blocking.DBusConnection connection: Connection to send and receive messages :param float timeout: Default seconds to wait for a reply, or None for no limit Nr6cst|||_||_dSr)rxr$ _connection_timeout)r!msggen connectionr7rr"r#r$s  zProxy.__init__cCs4|jdurdnd|j}d|jd|j|dS)Nz , timeout=zProxy(z, ))r_msggenr)r!extrar"r"r#__repr__szProxy.__repr__cstfdd}|S)Ncs@|dj}|i|}|jjtjusJjj||ddS)NrTr)poprr message_typer method_callrr)argskwargsr7ramake_msgr!r"r#inner s z!Proxy._method_call..inner) functoolswraps)r!rrr"rr# _method_callszProxy._method_call)r1r2r3rvr$rrrr"r"rr#rs rcCs|s tttt|S)zRaise ConnectionResetError from an empty read.

An error will be raised if the bus does not allow this. For simplicity, it's advisable to leave this disabled unless you need it. D-Bus has an authentication step before sending or receiving messages. This takes < 1 ms in normal operation, but there is a timeout so that client code won't get stuck if the server doesn't reply. *auth_timeout* configures this timeout in seconds. r6)rrr)busr? auth_timeoutbus_addrr=connr"r"r#r>s r__main__z Unique name:)Fr)rFr)7rvrR collectionsrerrnorr itertoolsrr selectorsrrrWr4typingrjeepneyrr r r jeepney.authr r jeepney.busr jeepney.fdsrrjeepney.wrappersrrjeepney.routingrjeepney.bus_messagesrcommonrrr__all__rr8r;r<rrrfrrr1rprintrEr"r"r"r#sH       Cm(
