facility for writing and reading grids

facility for writing and reading a SPGrid

The BackupRestoreFacility allows writing hierarchic grids to disk and reading them back into another program.

It is guaranteed that all index sets and id sets are preserved by the backup / restore process. The result of restore is undefined, if the number of processes in a parallel program differs from the number of processes used on backup.

There are two pairs of backup / restore methods:

• methods writing into one or more dedicated files,
• methods operating on a std::stream.

These techniques may not be mixed, i.e., you cannot write the grid into files and read it back from a stream or vice versa. While operating on a std::stream might be convenient, a grid written in another language than C++ might need to emulate this method by writing through a temporary file.

Note

The backup and restore methods might not be implemented for each grid. In this case one can catch the Dune::NotImplemented exception and do something else.
