Dumping Attributes with H5Easy to H5 Groups / Root

[mgaimann]

Hello,

I would like to add attributes to the root of a H5 file (which is a group and not a dataset).

When trying to do this via

H5Easy::dumpAttribute(h5File, "/", "seed", 12345);

the error

    if (file.getObjectType(path) != ObjectType::Dataset) {
        throw error(file, path, "H5Easy::dumpAttribute: path not a DataSet");
    }

appears (defined in the file H5Easy_misc.hpp). Dumping to a dataset works perfectly fine.

Is dumping attributes to groups not supported with H5Easy? Is it supported at all? (I could not find such case in the referenced example).

What would you suggest as a solution? Creating an "empty" or "dummy" dataset at the root and dumping the attributes there?

Thank you for your help :)

Thank you for reporting this bug. I've improved the examples to show how it can be done using core HighFive in #758. Note that a H5Easy::File is just a HighFive::File.
