org.openjena.atlas.lib.ColumnMap
General descriptor of a reordering (mapping) of columns in tuples to columns in indexes, for example, from triples to triple index order. Naming: map is convert to the reordered form, fetch is get back.

    protected TupleIndex makeTupleIndex(Location location, String name, String primary, String indexOrder)
    {
        // Commonly,  name == indexOrder.
        // FileSet
        FileSet fs = new FileSet(location, name) ;
        ColumnMap colMap = new ColumnMap(primary, indexOrder) ;
        return tupleIndexBuilder.buildTupleIndex(fs, colMap, indexOrder) ;
    }

          if ( tupleLength == 3 ) {
              primaryOrder = Names.primaryIndexTriples;
          } else if ( tupleLength == 4 ) {
              primaryOrder = Names.primaryIndexQuads;
          }
          ColumnMap colMap = new ColumnMap(primaryOrder, indexName) ;
      
      while (iter.hasNext()) {
        Record record = iter.next();
        System.out.println(record);
        Tuple<NodeId> tuple = TupleLib.tuple(record, colMap);
