public interface RowSequence extends Closeable, RowData, Sequence
Typical usage might look like this:
RowSequence rseq = table.getRowSequence(); try { while ( rseq.next() ) { Object[] row = rseq.getRow(); ... } } finally { rseq.close(); }
A RowSequence cannot in general be expected to be used safely from multiple threads.
