```
public class SequentialJELRowReader
extends StarTableJELRowReader
implements uk.ac.starlink.table.RowSequence
```
Implements JELRowReader for sequential access to a table. This class also implements RowSequence, and this object should be treated in the same way as a row sequence taken out on its table, that is iteration should proceed using the next and close methods.
