 javax.swing.table.AbstractTableModel
All known Subclasses: javax.swing.table.DefaultTableModel,
| AbstractTableModel | | abstract public class AbstractTableModel implements TableModel,Serializable(Code) | | 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 JavaBeansTM
has been added to the java.beans package.

| Method Summary | |
| public void | addTableModelListener(TableModelListener l)
Adds a listener to the list that's notified each time a change
to the data model occurs. | | 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. | | public void | fireTableCellUpdated(int row, int column)
Notifies all listeners that the value of the cell at
[row, column] has been updated. | | public void | fireTableChanged(TableModelEvent e)
Forwards the given notification event to all
TableModelListeners that registered
themselves as listeners for this table model. | | public void | fireTableDataChanged()
Notifies all listeners that all cell values in the table's
rows may have changed. | | public void | fireTableRowsDeleted(int firstRow, int lastRow)
Notifies all listeners that rows in the range
[firstRow, lastRow], inclusive, have been deleted. | | public void | fireTableRowsInserted(int firstRow, int lastRow)
Notifies all listeners that rows in the range
[firstRow, lastRow], inclusive, have been inserted. | | public void | fireTableRowsUpdated(int firstRow, int lastRow)
Notifies all listeners that rows in the range
[firstRow, lastRow], inclusive, have been updated. | | 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. | | public Class | getColumnClass(int columnIndex)
Returns Object.class regardless of columnIndex. | | public String | getColumnName(int column)
Returns a default name for the column using spreadsheet conventions:
A, B, C, ... | | public T[] | getListeners(Class<T> listenerType)
Returns an array of all the objects currently registered
as FooListeners
upon this AbstractTableModel. | | public TableModelListener[] | getTableModelListeners()
Returns an array of all the table model listeners
registered on this model. | | public boolean | isCellEditable(int rowIndex, int columnIndex)
Returns false. | | public void | removeTableModelListener(TableModelListener l)
Removes a listener from the list that's notified each time a
change to the data model occurs. | | 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. |
| addTableModelListener | | public void addTableModelListener(TableModelListener l)(Code) | | Adds a listener to the list that's notified each time a change
to the data model occurs.
Parameters:
l - the TableModelListener |
| findColumn | | public int findColumn(String columnName)(Code) | | 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 the column with columnName, or -1 if not found |
| fireTableCellUpdated | | public void fireTableCellUpdated(int row, int column)(Code) | | Notifies all listeners that the value of the cell at
[row, column] has been updated.
Parameters:
row - row of cell which has been updated
Parameters:
column - column of cell which has been updated

| fireTableDataChanged | | public void fireTableDataChanged()(Code) | | 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.

| fireTableRowsDeleted | | public void fireTableRowsDeleted(int firstRow, int lastRow)(Code) | | Notifies all listeners that rows in the range
[firstRow, lastRow], inclusive, have been deleted.
Parameters:
firstRow - the first row
Parameters:
lastRow - the last row
See Also: TableModelEvent
See Also: EventListenerList |
| fireTableRowsInserted | | public void fireTableRowsInserted(int firstRow, int lastRow)(Code) | | Notifies all listeners that rows in the range
[firstRow, lastRow], inclusive, have been inserted.
Parameters:
firstRow - the first row
Parameters:
lastRow - the last row
See Also: TableModelEvent
See Also: EventListenerList |
| fireTableRowsUpdated | | public void fireTableRowsUpdated(int firstRow, int lastRow)(Code) | | Notifies all listeners that rows in the range
[firstRow, lastRow], inclusive, have been updated.
Parameters:
firstRow - the first row
Parameters:
lastRow - the last row

| fireTableStructureChanged | | public void fireTableStructureChanged()(Code) | | 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 Also: EventListenerList |
| getColumnClass | | public Class getColumnClass(int columnIndex)(Code) | | Returns Object.class regardless of columnIndex.
Parameters:
columnIndex - the column being queried the Object.class |
| getColumnName | | public String getColumnName(int column)(Code) | | 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.
Parameters:
column - the column being queried a string containing the default name of column |
| getListeners | | public T[] getListeners(Class<T> listenerType)(Code) | | 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 parametershould specify an interface that descends fromjava.util.EventListener an array of all objects registered asFooListeners on this component,or an empty array if no suchlisteners have been added
exception:
ClassCastException - if listenerTypedoesn't specify a class or interface that implementsjava.util.EventListener

| isCellEditable | | public boolean isCellEditable(int rowIndex, int columnIndex)(Code) | | Returns false. This is the default implementation for all cells.
Parameters:
rowIndex - the row being queried
Parameters:
columnIndex - the column being queried false |
| removeTableModelListener | | public void removeTableModelListener(TableModelListener l)(Code) | | Removes a listener from the list that's notified each time a
change to the data model occurs.
Parameters:
l - the TableModelListener |
| setValueAt | | public void setValueAt(Object aValue, int rowIndex, int columnIndex)(Code) | | This empty implementation is provided so users don't have to implement
this method if their data model is not editable.
Parameters:
aValue - value to assign to cell

rowIndex - row of cell
