Hi Fotis
I understand that jClouds generates the http calls for each concrete
provider but I cannot find the exact class that does this and where it gets
the information for the required attributes from.
Glad you're interested in jclouds! For a general overview of the
architectural concepts, you can try the 'Core Concepts' document on
the wiki page [1].
As regards the lower-level details, the HTTP call generation largely
happens in the RestAnnotationProcessor [2]. In many cases, concrete
implementations are encapsulated in "strategies" (e.g. [3, 4]) that
are injected abstraction layer classes like BaseComputeService [5] by
Guice.
Luckily, you'll find that BaseBlobStore is somewhat less complex than
BaseComputeService ;-)
This is only a very high-level sketch: please feel free to hop on to
IRC for further discussion!
