org.apache.derby.iapi.types.LocatedRow

Mutable holder for the column values and RowLocation of a conglomerate row. Use with caution because values and arrays are not copied when they are passed in and out.

            columnValues = cloneRow( columnValues );
        }


        Object key = KeyHasher.buildHashKey( columnValues, key_column_numbers );
        Object hashValue = !includeRowLocations() ?
            columnValues : new LocatedRow( columnValues, rowLocation );
        Object duplicate_value = hash_table.put( key, hashValue );


        if (duplicate_value == null)
        {
            doSpaceAccounting( hashValue, false );
