- * PURPOSE:
- * This class represents a MArray with base type long.
- * @version $Revision: 1.7 $
- * for ODMG type Long(4 bytes, due to ODMG standard) please use RasMArrayInteger,
- * for ODMG type ULong(4 bytes, due to ODMG standard) you can use RasMArrayLong,
- * but only values up to 2^32 (performance loss because of convertion 8 bytes-> 4 bytes!);
- * method intersectionWith(RasMInterval) uses byte array and is not optimized for special data arrays
- *
- *
- *
- * COMMENTS:
- *
- * </pre>
