Abstract AnnData class

This class is an abstract representation of an AnnData object. It is intended to be used as a base class for concrete implementations of AnnData objects, such as InMemoryAnnData or HDF5AnnData.

See AnnData-usage for details on creating and using AnnData objects.

Value

An AbstractAnnData object
