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. ) ProxyMethodClassrBr(rDrIrJDeferredMethodClassrbr`)rrhr1retrrrrgs   zProxyObject.get_dbus_methodcCsd|j|j|jt|fS)Nz&)rBr(rDid)rrrr__repr__szProxyObject.__repr__)NNNTF)N)N)r!r"r#r$r%rjrrkrHrJrWrpropertyr-requested_bus_namer.rQrKrUrSrTr`rbrirgrn__str__rrrrr7s6 R  C    &r7c@seZdZdZddZedddddZeZeddddd Zed dddd Z ed dddd Z edddddZ dddZ ddZ dddZddZeZdS) InterfacezAn interface into a remote object.
