Fields Summary
protected EventListenerList	listenerList List of listeners

Constructors Summary

Methods Summary
public void	addTableModelListener(javax.swing.event.TableModelListener l) Adds a listener to the list that's notified each time a change to the data model occurs. param l the TableModelListener listenerList.add(TableModelListener.class, l);
public int	findColumn(java.lang.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. param columnName string containing name of column to be located return the column with columnName, or -1 if not found for (int i = 0; i < getColumnCount(); i++) { if (columnName.equals(getColumnName(i))) { return i; } } return -1;
public void	fireTableCellUpdated(int row, int column) Notifies all listeners that the value of the cell at [row, column] has been updated. param row row of cell which has been updated param column column of cell which has been updated see TableModelEvent see EventListenerList fireTableChanged(new TableModelEvent(this, row, row, column));
public void	fireTableChanged(javax.swing.event.TableModelEvent e) Forwards the given notification event to all TableModelListeners that registered themselves as listeners for this table model. param e the event to be forwarded see #addTableModelListener see TableModelEvent see EventListenerList // Guaranteed to return a non-null array Object[] listeners = listenerList.getListenerList(); // Process the listeners last to first, notifying // those that are interested in this event for (int i = listeners.length-2; i>=0; i-=2) { if (listeners[i]==TableModelListener.class) { ((TableModelListener)listeners[i+1]).tableChanged(e); } }
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 TableModelEvent see EventListenerList see javax.swing.JTable#tableChanged(TableModelEvent) fireTableChanged(new TableModelEvent(this));
public void	fireTableRowsDeleted(int firstRow, int lastRow) Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been deleted. param firstRow the first row param lastRow the last row see TableModelEvent see EventListenerList fireTableChanged(new TableModelEvent(this, firstRow, lastRow, TableModelEvent.ALL_COLUMNS, TableModelEvent.DELETE));
public void	fireTableRowsInserted(int firstRow, int lastRow) Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been inserted. param firstRow the first row param lastRow the last row see TableModelEvent see EventListenerList fireTableChanged(new TableModelEvent(this, firstRow, lastRow, TableModelEvent.ALL_COLUMNS, TableModelEvent.INSERT));
public void	fireTableRowsUpdated(int firstRow, int lastRow) Notifies all listeners that rows in the range [firstRow, lastRow], inclusive, have been updated. param firstRow the first row param lastRow the last row see TableModelEvent see EventListenerList fireTableChanged(new TableModelEvent(this, firstRow, lastRow, TableModelEvent.ALL_COLUMNS, TableModelEvent.UPDATE));
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. see TableModelEvent see EventListenerList fireTableChanged(new TableModelEvent(this, TableModelEvent.HEADER_ROW));
public java.lang.Class	getColumnClass(int columnIndex) Returns Object.class regardless of columnIndex. param columnIndex the column being queried return the Object.class return Object.class;
public java.lang.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. param column the column being queried return a string containing the default name of column // // Default Implementation of the Interface // String result = ""; for (; column >= 0; column = column / 26 - 1) { result = (char)((char)(column%26)+'A") + result; } return result;
public T[]	getListeners(java.lang.Class 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. param listenerType the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener return an array of all objects registered as FooListeners on this component, or an empty array if no such listeners have been added exception ClassCastException if listenerType doesn't specify a class or interface that implements java.util.EventListener see #getTableModelListeners since 1.3 return listenerList.getListeners(listenerType);
public javax.swing.event.TableModelListener[]	getTableModelListeners() Returns an array of all the table model listeners registered on this model. return all of this model's TableModelListeners or an empty array if no table model listeners are currently registered see #addTableModelListener see #removeTableModelListener since 1.4 return (TableModelListener[])listenerList.getListeners( TableModelListener.class);
public boolean	isCellEditable(int rowIndex, int columnIndex) Returns false. This is the default implementation for all cells. param rowIndex the row being queried param columnIndex the column being queried return false return false;
public void	removeTableModelListener(javax.swing.event.TableModelListener l) Removes a listener from the list that's notified each time a change to the data model occurs. param l the TableModelListener listenerList.remove(TableModelListener.class, l);
public void	setValueAt(java.lang.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. param aValue value to assign to cell param rowIndex row of cell param columnIndex column of cell
