Partha, what are you saying here?

parent_class.connect() will only call the super-class method.

Transport doesn't derive from Store, they both derive from Service.

So if you want to share the connect() implementation from both classes,
then it must be implemented in a sharable manner, and not separately.

Hence my original comment about merging the Transport and Store objects.
Infact ideally they would probably both be optional interfaces on a
Service rather than separate classes.

FWIW, I hope to be writing a decent amount of Camel documentation in the
coming weeks; a lot of it needs much more documentation beyond the
comments in the code, and many of the implementations to use as examples
aren't very clean.
