Hi Peter, > What I am going to ask may not make much sense to you. > Can we set and get name for Tuple ?

The visad.Tuple class does not have a name field, but your HDF-5 adapter could construct its Data objects using an extension of Tuple such as: public class NamedTuple extends Tuple { private String name; public NamedTuple(TupleType type, Data[] datums, boolean copy, String n) throws VisADException, RemoteException { super(type, datums, copy); name = n; } // . . . other constructors public String getName() { return name; } } Of course, VisAD's internal logic would know nothing about this, so for example adding two such Data objects would produce a result that did not use any NamedTuples. If this is a problem for you, we could add a name String field to visad.Tuple. Cheers, Bill ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
