    • getObject

      public java.lang.Object getObject(int row, int column)
      Returns the object from a particular cell in the table. Returns null, if there is no object at the given position.

      Note: throws IndexOutOfBoundsException if row or column is negative.

      Parameters:
      row - the row index (zero-based).
      column - the column index (zero-based).
      Returns:
      The object.
    • setObject

      public void setObject(int row, int column, java.lang.Object object)
      Sets the object for a cell in the table. The table is expanded if necessary.

      row - the row index (zero-based).
      column - the column index (zero-based).
      object - the object.
    • copyColumn

      public void copyColumn(int oldColumn, int newColumn)
      Copys the contents of the old column to the new column.
      Parameters:
      oldColumn - the index of the old (source) column
      newColumn - the index of the new column
    • copyRow

      public void copyRow(int oldRow, int newRow)
      Copys the contents of the old row to the new row. This uses raw access to the data and is remarkably faster than manual copying.
