New in version (cfdm): 1.11.2.0

nc_hdf5_chunksizes, nc_set_hdf5_chunksizes, cfdm.read, cfdm.write

Parameters
constructs: dict or bool, optional

Also clear the HDF5 chunking strategy from selected metadata constructs. The chunking strategies of unselected metadata constructs are unchanged.

If constructs is a dict then the selected metadata constructs are those that would be returned by f.constructs.filter(**constructs, filter_by_data=True). Note that an empty dictionary will therefore select all metadata constructs that have data. See filter for details.

For constructs being anything other than a dictionary, if it evaluates to True then all metadata constructs that have data are selected, and if it evaluates to False (the default) then no metadata are constructs selected.

Returns
None or str or int or tuple of int

The chunking strategy prior to being cleared, as would be returned by nc_hdf5_chunksizes.
