Detailed Description

The saga::replica class implements the saga::attributes interface.

A checkpoint represents merely an entry in a name space which has (a) an associated set of registered (physical) checkpoint files of that checkpoint, and (b) an associated set of meta data describing that checkpoint. Both sets can be empty. To access the content of a checkpoint, a saga::file needs to be created with one of the registered file locations.
