Detailed Description

Classes of basic data encapsulations that allow abstraction and re-use across the Aft interface.

AftData implements a wrapper class that allows data to be encapsulated with some state as to what the underlying data actually is (whether it's an index, an IP address or an MPLS label). This allows us to do two things

• Abstract data references in the Aft client (and server)
• Add context to allow additional error checking on the client and the server

Obviously, we trade off some memory footprint for the extra context but this allows us to provide a rich interface for lookup key management, for example.
