I'm trying to write an attribute that just has a single string as data and I do not want it wrapped in an array. The Attribute class' JavaDoc suggests you could set the dimensions to null for scalar data, but line 1743 ind H5File does not handle that case:
sid = H5.H5Screate_simple(attr.getRank(), attr.getDataDims(), null);
I guess it should do
if (attr.getDataDims() == null) {
sid = H5.H5Screate(HDF5Constants.H5S_SCALAR);
} else {
sid = H5.H5Screate_simple(attr.getRank(), attr.getDataDims(), null);
}
The only other way is in the client code to revert to using all that H5.* stuff yourself, with all the int ids and return value checking you'd rather avoid in Java.
I haven't tried the above code, but does that look reasonable? Did I miss another way of doing the same thing?
Cheers,
Tobias
