public interface NavigatableRowIterator

extends RowIterator

Provides simple access to a set of rows.

View Object methods may use row set iterators to navigate through a row set resulting from a query. Row set iterators provide a window into the row set, making a subset of it accessible. Each row of the row set is represented by a Row object.
