      • next

        @Nullable
public Result next()
        Move the cursor forward one row from its current row position. Caution: next() method and iterator() method share same data structure. Please don't use them together. Caution: In case ResultSet is obtained from QueryChangeListener, and QueryChangeListener is already removed from Query, ResultSet is already freed. And this next() method returns null.
        Returns:
        the Result after moving the cursor forward. Returns null value if there are no more rows, or ResultSet is freed already.
