Class AbstractTableModel

Field Detail

• listenerList

  protected EventListenerList listenerList

  List of listeners

Constructor Detail

• AbstractTableModel

  public AbstractTableModel()

Method Detail

• getColumnName

  public String getColumnName(int column)

  Returns a default name for the column using spreadsheet conventions: A, B, C, ... Z, AA, AB, etc. If column cannot be found, returns an empty string.

  Specified by:

  getColumnName in interface TableModel

  Parameters:

  column - the column being queried

  Returns:

  a string containing the default name of column

• findColumn

  public int findColumn(String columnName)

  Returns a column given its name. Implementation is naive so this should be overridden if this method is to be called often. This method is not in the TableModel interface and is not used by the JTable.

  Parameters:

  columnName - string containing name of column to be located

  Returns:

  the column with columnName, or -1 if not found

• getColumnClass

  public Class<?> getColumnClass(int columnIndex)

  Returns Object.class regardless of columnIndex.

  Specified by:

  getColumnClass in interface TableModel

  Parameters:

  columnIndex - the column being queried

  Returns:

  the Object.class

• isCellEditable

  public boolean isCellEditable(int rowIndex,
                       int columnIndex)

  Returns false. This is the default implementation for all cells.

  Specified by:

  isCellEditable in interface TableModel

  Parameters:

  rowIndex - the row being queried

  columnIndex - the column being queried

  Returns:

  false

  TableModel.setValueAt(java.lang.Object, int, int)

• setValueAt

  public void setValueAt(Object aValue,
                int rowIndex,
                int columnIndex)

  This empty implementation is provided so users don't have to implement this method if their data model is not editable.

  Specified by:

  setValueAt in interface TableModel

  Parameters:

  aValue - value to assign to cell

  rowIndex - row of cell

  columnIndex - column of cell

  TableModel.getValueAt(int, int), TableModel.isCellEditable(int, int)

• addTableModelListener

  public void addTableModelListener(TableModelListener l)

  Adds a listener to the list that's notified each time a change to the data model occurs.

  Specified by:

  addTableModelListener in interface TableModel

  Parameters:

  l - the TableModelListener

• removeTableModelListener

  public void removeTableModelListener(TableModelListener l)

  Removes a listener from the list that's notified each time a change to the data model occurs.

  Specified by:

  removeTableModelListener in interface TableModel

  Parameters:

  l - the TableModelListener

• getTableModelListeners

  public TableModelListener[] getTableModelListeners()

  Returns an array of all the table model listeners registered on this model.

  Returns:

  all of this model's TableModelListeners or an empty array if no table model listeners are currently registered

  Since:

  1.4

• fireTableDataChanged

  public void fireTableDataChanged()

  Notifies all listeners that all cell values in the table's rows may have changed. The number of rows may also have changed and the JTable should redraw the table from scratch. The structure of the table (as in the order of the columns) is assumed to be the same.

  See Also:

  TableModelEvent, EventListenerList, JTable.tableChanged(TableModelEvent)

• fireTableStructureChanged

  public void fireTableStructureChanged()

  Notifies all listeners that the table's structure has changed. The number of columns in the table, and the names and types of the new columns may be different from the previous state. If the JTable receives this event and its autoCreateColumnsFromModel flag is set it discards any table columns that it had and reallocates default columns in the order they appear in the model. This is the same as calling setModel(TableModel) on the JTable.

  TableModelEvent, EventListenerList

• fireTableRowsInserted

  public void fireTableRowsInserted(int firstRow,
                           int lastRow)

  Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been inserted.

  Parameters:

  firstRow - the first row

  lastRow - the last row

  See Also:

  TableModelEvent, EventListenerList

• fireTableRowsUpdated

  public void fireTableRowsUpdated(int firstRow,
                          int lastRow)

  Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been updated.

  Parameters:

  firstRow - the first row

  lastRow - the last row

  See Also:

  TableModelEvent, EventListenerList

• fireTableRowsDeleted

  public void fireTableRowsDeleted(int firstRow,
                          int lastRow)

  Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been deleted.

  Parameters:

  firstRow - the first row

  lastRow - the last row

  See Also:

  TableModelEvent, EventListenerList

• fireTableCellUpdated

  public void fireTableCellUpdated(int row,
                          int column)

  Notifies all listeners that the value of the cell at [row, column] has been updated.

  Parameters:

  row - row of cell which has been updated

  column - column of cell which has been updated

  See Also:

  TableModelEvent, EventListenerList

• fireTableChanged

  public void fireTableChanged(TableModelEvent e)

  Forwards the given notification event to all TableModelListeners that registered themselves as listeners for this table model.

  Parameters:

  e - the event to be forwarded

  See Also:

  addTableModelListener(javax.swing.event.TableModelListener), TableModelEvent, EventListenerList

• getListeners

  public <T extends EventListener> T[] getListeners(Class<T> listenerType)

  Returns an array of all the objects currently registered as FooListeners upon this AbstractTableModel. FooListeners are registered using the addFooListener method.

  You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a model m for its table model listeners with the following code:

  TableModelListener[] tmls = (TableModelListener[])(m.getListeners(TableModelListener.class));

  If no such listeners exist, this method returns an empty array.

  Parameters:

  listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener

  Returns:

  an array of all objects registered as FooListeners on this component, or an empty array if no such listeners have been added

  Throws:

  ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener

  1.3
