Class AbstractTableModel

java.lang.Object

javax.swing.table.AbstractTableModel

All Implemented Interfaces:

Serializable, TableModel

Direct Known Subclasses:

DefaultTableModel

public abstract class AbstractTableModel
extends Object
implements TableModel, Serializable

This abstract class provides default implementations for most of the methods in the TableModel interface. It takes care of the management of listeners and provides some conveniences for generating TableModelEvents and dispatching them to the listeners. To create a concrete TableModel as a subclass of AbstractTableModel you need only provide implementations for the following three methods:

  public int getRowCount();
  public int getColumnCount();
  public Object getValueAt(int row, int column);
  

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.

Method Summary

Modifier and Type	Method	Description
void	addTableModelListener(TableModelListener l)	Adds a listener to the list that's notified each time a change to the data model occurs.
int	findColumn(String columnName)	Returns a column given its name.
void	fireTableCellUpdated(int row, int column)	Notifies all listeners that the value of the cell at [row, column] has been updated.
void	fireTableChanged(TableModelEvent e)	Forwards the given notification event to all TableModelListeners that registered themselves as listeners for this table model.
void	fireTableDataChanged()	Notifies all listeners that all cell values in the table's rows may have changed.
void	fireTableRowsDeleted(int firstRow, int lastRow)	Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been deleted.
void	fireTableRowsInserted(int firstRow, int lastRow)	Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been inserted.
void	fireTableRowsUpdated(int firstRow, int lastRow)	Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been updated.
void	fireTableStructureChanged()	Notifies all listeners that the table's structure has changed.
Class<?>	getColumnClass(int columnIndex)	Returns Object.class regardless of columnIndex.
String	getColumnName(int column)	Returns a default name for the column using spreadsheet conventions: A, B, C, ...
<T extends EventListener> T[]	getListeners(Class<T> listenerType)	Returns an array of all the objects currently registered as FooListeners upon this AbstractTableModel.
TableModelListener[]	getTableModelListeners()	Returns an array of all the table model listeners registered on this model.
boolean	isCellEditable(int rowIndex, int columnIndex)	Returns false.
void	removeTableModelListener(TableModelListener l)	Removes a listener from the list that's notified each time a change to the data model occurs.
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.
