  - ### Method Detail

    - #### iterator

          public Iterator<T> iterator()

      Specified by:
        `iterator` in interface `Iterable<T>`
      Since:
        4.0

    - #### close

          public void close()

      Description copied from interface: `ResultIterator`
      Closes ResultIterator and associated ResultSet. This method must be called explicitly when the user is finished processing the records. Otherwise unused database resources will not be released properly.
      Specified by:
        `close` in interface `AutoCloseable`
      Specified by:
        `close` in interface `ResultIterator<T>`

    - #### allRows

          public List<T> allRows()

      Description copied from interface: `ResultIterator`
      Returns all yet unread rows from ResultSet without closing it.
      Specified by:
        `allRows` in interface `ResultIterator<T>`
      Since:
        3.0

    - #### hasNextRow

          public boolean hasNextRow()

      Description copied from interface: `ResultIterator`
      Returns true if there is at least one more record that can be read from the iterator.
      Specified by:
        `hasNextRow` in interface `ResultIterator<T>`

    - #### nextRow

          public T nextRow()

      Description copied from interface: `ResultIterator`
      Returns the next result row that is, depending on the query, may be a scalar value, a DataRow, or an Object[] array containing a mix of scalars and DataRows.
      Specified by:
        `nextRow` in interface `ResultIterator<T>`
      Since:
        3.0

    - #### skipRow

          public void skipRow()

      Description copied from interface: `ResultIterator`
      Goes past current row. If the row is not needed, this may save some time on data conversion.
      Specified by:
        `skipRow` in interface `ResultIterator<T>`
      Since:
