Class TableMap

java.lang.Object

javax.swing.table.AbstractTableModel

us.daveread.basicquery.util.TableMap

All Implemented Interfaces:

java.io.Serializable, java.util.EventListener, javax.swing.event.TableModelListener, javax.swing.table.TableModel

Direct Known Subclasses:

TableSorter

public class TableMap
extends javax.swing.table.AbstractTableModel
implements javax.swing.event.TableModelListener

In a chain of data manipulators some behaviour is common. TableMap provides most of this behavour and can be subclassed by filters that only need to override a handful of specific methods. TableMap implements TableModel by routing all requests to its model, and TableModelListener by routing all events to its listeners. Inserting a TableMap which has not been subclassed into a chain of table filters should have no effect.

java.lang.String	getColumnName(int aColumn) Returns the column name at the column index
javax.swing.table.TableModel	getModel() Implements TableModel by forwarding all messages to the model
int	getRowCount() Returns the number of rows in the model
java.lang.Object	getValueAt(int aRow, int aColumn) Returns the value of the cell at aRow and aColumn
boolean	isCellEditable(int row, int column) Returns true if the cell at row and column is editable If the cell is not editable then the setValueAt will not change the value
void	removeModel(javax.swing.table.TableModel pModel) Remove the model from this instance, removing this instance as a listener as well TODO Either don't pass the model or verify that it is the current model backing this instance
void	setModel(javax.swing.table.TableModel pModel) Sets the table model for this model and adds a listener to the model that's notified each time a change occurs
void	setValueAt(java.lang.Object aValue, int aRow, int aColumn) Sets the value in the cell at aRow and aColumn to aValue
void	tableChanged(javax.swing.event.TableModelEvent e) To fulfill the TableModelListener interface By default forward all events to all the listeners The notification that tells the listeners the exact range of cells,rows,or columns that changed

Specified by:

getValueAt in interface javax.swing.table.TableModel

Parameters:

aRow - The row whose value is queried

aColumn - The column whose value is queried

Returns:

The object at the specified cell

setValueAt

public void setValueAt(java.lang.Object aValue,
              int aRow,
              int aColumn)

isCellEditable

public boolean isCellEditable(int row,
                     int column)

Returns true if the cell at row and column is editable If the cell is not editable then the setValueAt will not change the value

The object with the true value if the cell is editable

tableChanged

public void tableChanged(javax.swing.event.TableModelEvent e)

To fulfill the TableModelListener interface By default forward all events to all the listeners The notification that tells the listeners the exact range of cells,rows,or columns that changed

Specified by:

tableChanged in interface javax.swing.event.TableModelListener

Parameters:

e - The table model event object that represents the event-fired.
