//Amended by paul johnson June 26 to move class DataRecord outside of the
//InnerClassHDFDemo class. It crashed under JDK otherwise.

//Marcus Daniels June 26, 2001, swarm-support

//  First off, you can't put arrays in objects that are stored `shallow'.
//  The other thing is that any ivars you want picked up should be tagged public.

//  Here's an example.  The first time it is run it will write the HDF5 file,
//  and the second time it will print out what it finds.
