  - ### 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:
      3.0
