Hi all,

I would like to know how can I define a FlatField with a range component
taking table values (no topology).  I tried the following:

class TestTableValuesAsRange {
    
   public TestTableValuesAsRange() 
    throws RemoteException, VisADException
   {
      // Generate the index
      RealType index = RealType.getRealType("index");
      Set index_set = new Integer1DSet(index, 5);

      // My range component
      List1DSet list_set =new List1DSet(new float[] {1.0f, 2.0f, 3.0f},
                  RealType.getRealType("list_of_system_ids"), null, null);

      RealType id=RealType.getRealType("System_id", null, list_set);

      // Create a FunctionType ( index -> id )      
      FunctionType data_type = new FunctionType(index, id);
      
      // Create the flat field
      FlatField aFlatField = new FlatField( data_type, index_set);
      
      // Put some samples values
      aFlatField.setSamples(new double [][] {{1.0, 1.0, 2.0, 1.0, 3.0}});  
      
      // Print out
      System.out.println("Results is " + aFlatField);

   }
    
   public static void main (String[] args)
       throws RemoteException, VisADException 
   {
      TestTableValuesAsRange myTest = new TestTableValuesAsRange();

   }    
    
}


but, i'm always getting:

Exception in thread "main" visad.UnimplementedException:
List1DSet.valueToIndex
        at visad.List1DSet.valueToIndex(List1DSet.java:82)
        at visad.FlatField.packValues(FlatField.java:932)
        at visad.FlatField.setSamples(FlatField.java:700)
        at visad.FlatField.setSamples(FlatField.java:652)
        at TestTableValuesAsRange.<init>(TestTableValuesAsRange.java:26)
        at TestTableValuesAsRange.main(TestTableValuesAsRange.java:36)


Do I need to sub-class List1DSet in order to use it?  Can I do the same
thing using something else?
