A convenience class to assist with managing archives for parallel checkpointing.
When checkpointing a parallel simulation, there are two kinds of data that need to be saved: replicated (same for every process) and distributed (different on each process). We wish to write these to separate archive files. This class hides the complexity of doing so, such that all a user needs to do is create an instance of this class, call GetCommonArchive, and read from/write to the returned archive. When done, just destroy the instance (e.g. by closing the scope).
Internally the class uses ProcessSpecificArchive<Archive> to store the secondary archive.
Note also that implementations of this templated class only exist for text archives, i.e. Archive = boost::archive::text_iarchive (with Stream = std::ifstream), or Archive = boost::archive::text_oarchive (with Stream = std::ofstream).

) |
Open the archives for this process, either for reading or writing depending on the template parameter Archive.
Note that when writing, only the master process writes to the main archive. For other processes the main archive is a dummy, writing to /dev/null.
If writing, and rDirectory is relative to CHASTE_TEST_OUTPUT, it will be created if it doesn't exist.
rDirectory | folder containing archive files. |
rFileNameBase | base name of archive files. This will be used for the main archive (for replicated data) with ".n" (where n is the process index) being appended for the secondary archive. |
procId | this can be specified to read a specific secondary archive, rather than this process' default. Should not be used for writing! |
