Class AbstractTableModel

java.lang.Object

charvax.swing.table.AbstractTableModel

All Implemented Interfaces:

TableModel

Direct Known Subclasses:

DefaultTableModel

public abstract class AbstractTableModel
extends java.lang.Object
implements TableModel

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

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

AbstractTableModel()

Method Summary

Modifier and Type	Method and Description
void	addTableModelListener(TableModelListener l) Adds a listener that will be notified each time the data model changes.
void	fireTableCellUpdated(int row_, int column_) Notifies all listeners that the value at [row, column] has been updated.
void	fireTableChanged(TableModelEvent evt_) Forwards the specified event to all TableModelListeners that registered themselves as listeners for this TableModel.
void	fireTableDataChanged() Notifies all listeners that all cell values in the table 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.
java.lang.String	getColumnName(int column_) Returns a default name for the column using spreadsheet conventions: A, B, C...
abstract int	getRowCount() Get the number of rows in the model.
void	removeTableModelListener(TableModelListener l) Removes the specified listener from the list of listeners.
void	setValueAt(java.lang.Object value_, int row_, int column_) This empty implementation is provided so that users don't have to provide their own implementation if their table is not editable.
