selectHyperslab

public static final long selectHyperslab(long did,
 long[] dsetDims,
 long[] startDims,
 long[] selectedStride,
 long[] selectedDims,
 long[] spaceIDs)
                                  throws hdf.hdf5lib.exceptions.HDF5Exception

Set up a hyperslab selection within a dataset.

Parameters:

did - IN dataset ID

dsetDims - IN dimensions

startDims - IN start dimensions

selectedStride - IN selected stride values

selectedDims - IN selected dimensions
