MemGroup

class caput.memdata.MemGroup(distributed=False, comm=None)

Bases: _BaseGroup

In memory implementation of the h5py.Group.

This class doubles as the memory implementation of h5py.File, object, since the distinction between a file and a group for in-memory data is moot.

Parameters:

distributedbool

Allow memh5 object to hold distributed datasets.

commMPI.Comm | None

MPI Communicator to distributed over. If not set, use MPI.COMM_WORLD.

property mode

String indicating if group is readonly (“r”) or read-write (“r+”).

MemGroup is always read-write.
