  Description copied from interface: RowSequence
  Attempts to advances the current row to the next one. If true is returned the attempt has been successful, and if false is returned there are no more rows in this sequence.

  Overrides:

  next in class WrapperRowSequence

  Returns:

  true iff this sequence has been advanced to the next row

  Throws:

  java.io.IOException - if there is some error
