Sometime introspection doesnt work for remote object about txdbus HOT 2 OPEN

In order to call remote methods, an interface description is required.
Otherwise, the client code wouldn't know how to encode the arguments. The
interface can either be introspected on-the-fly or provided explicitly as
you're doing in your working code. Generally speaking, it's better to
provide an explicit interface as introspection isn't required by the DBus
specification and it only works if the object in question is online at the
time of the query. It's good for development and testing but I wouldn't
recommend relying upon it in production.

As to the API documentation, there isn't a well-documented API separate
from the tutorial. The docstrings are all there in the code but I never
figured out how to generate a separate doc with Lore. It might "just work"
but I haven't tried it. I recommend just browsing the modules on Github
directly. It's not quite as convenient as a standalone document but the
docstrings stick out pretty well and it's not a particularly large codebase.

Hi,

Is it mandatory to specify "Method" in interface explicitly?

=== Not working===
I tried following to call a remote method I wrote "ActivateConnection",
passed the argument using following piece of code:
Note I have not specified interface here

dialer_iface = DBusInterface(DIALUP_INTFACE)
self.dobj= yield self.mdmModel.bus.getRemoteObject(DIALUP_SERVICE,
DIALUP_OBJECT,dialer_iface)
self.path = yield
self.dobj.callRemote('ActivateConnection',self.mdmModel.device_opath,
timeout=80)
--> This gives an error that Remote Object doesnt have ActivateConnection
in any of interfaces --->

=== working===
Then I tried explicitly specifying the method in interface

dialer_iface = DBusInterface(DIALUP_INTFACE,
Method('ActivateConnection', 'o',returns=''))
self.dobj= yield self.mdmModel.bus.getRemoteObject(DIALUP_SERVICE,
DIALUP_OBJECT,dialer_iface)
self.path = yield
self.dobj.callRemote('ActivateConnection',self.mdmModel.device_opath,
timeout=80)

It works fine.. here, am I missing something?

• Also do you have API documentation for all public API ?
• Since from tutorial its tough to find all API definition and
  corresponding options

Thanks Tom, Yes now I am always using explicit definition. Will go through the code and if I comeup with a documentation, would try to share on the blog and give u the link
