public interface ScrollableResults
A result iterator that allows moving around within the results
by arbitrary increments. The Query / ScrollableResults
pattern is very similar to the JDBC PreparedStatement/
ResultSet pattern and the semantics of methods of this interface
are similar to the similarly named methods on ResultSet.
Contrary to JDBC, columns of results are numbered from zero.
