The name-indexed store contains only object UUIDs, indexed by the object names that they are stored (and looked up) by. Note that there is no place where we actually declare the data type of this database; all we do is declare the conversion routine (uu_convert( ), in the IDL file). The database is created without a header (the default), so all it will hold is UUIDs.
If, for some reason, we did want to declare a header, then we would have to go through the steps of declaring a separate complex data type for the store in the .idl file, wherein would be declared the header type and the UUID type.
