  public void addRow(Row row)
  
  Description copied from interface: ResultsetRows
  
  Adds a row.
  
  Specified by:
  
  addRow in interface ResultsetRows
  
  Parameters:
  
  row - the row to add
- afterLast
  
  public void afterLast()
  
  Description copied from interface: ResultsetRows
  
  Moves to after last.

  Description copied from interface: ResultsetRows
  
  Moves to before first.
  
  Specified by:
  
  beforeFirst in interface ResultsetRows
- beforeLast
  
  public void beforeLast()
  
  Description copied from interface: ResultsetRows
  
  Moves to before last.
  
  Specified by:
  
  beforeLast in interface ResultsetRows
- get
  
  public Row get(int atIndex)
  
  Description copied from interface: RowList
  
  Optionally retrieve Row at index n. Only works on non dynamic row lists.
  
  Specified by:
  
  get in interface RowList
  
  Parameters:
  
  atIndex - row number
  
  Returns:
  
  Row
- getPosition
  
  public int getPosition()
  
  Description copied from interface: RowList
  
  Returns the current position.
  
  Specified by:
  
  getPosition in interface RowList
  
  Returns:
  
  the current row number
- hasNext
  
  public boolean hasNext()
  
  Specified by:
  
  hasNext in interface java.util.Iterator<Row>
- isAfterLast
