public class ResultSetIterator extends Object implements DynaBean, Iterator<DynaBean>
Implementation of java.util.Iterator

object returned by this iterator will be a DynaBean
that
represents a single row from the result set being wrapped.

protected boolean |
eof
Flag indicating whether the result set has indicated that there are
no further rows.
