public class TreeTableModel
extends ListTableMap

TreeTableModel is the tablemodel that the TreeTable class uses. TreeTableModel wraps around a ListTableModel instance in order to provide a tree-like view of the table's data. Rows are grouped together if they are found to be equal by this class's row comparator. The default row comparator is a TreeTableModel.RowComparator, which compares rows by using a single column. However, more complex schemes can be employed, such as comparing using more than one columns. The current row comparator can be assigned with setRowComparator.

Constructor Detail

TreeTableModel

public TreeTableModel(ListTableModel tableModel)

Constructs a TreeTableModel with tableModel as the underlying tablemodel holding the data.

Method Detail

createDefaultRowComparator

protected Comparator createDefaultRowComparator()

Creates the default row comparator that will be used to determine row similarity. This method returns an instance of TreeTableModel.RowComparator that uses the first column of the table for the equality check.

fireTableChanged

public void fireTableChanged(TableModelEvent e)

Forwards the given notification event to all TableModelListeners that registered themselves as listeners for this table model.

Specified by:

fireTableChanged in interface ListTableModel

Overrides:

fireTableChanged in class AbstractTableModel

Parameters:

e - the event to be forwarded

See Also:

AbstractTableModel.addTableModelListener(javax.swing.event.TableModelListener), TableModelEvent, EventListenerList

getRowComparator

public Comparator getRowComparator()

Returns the Comparator instance that will be used to determine row similarity.

Returns:

the current row comparator instance

getRowCount

public int getRowCount()

Returns tableModel.getRowCount

Specified by:

getRowCount in interface TableModel

Overrides:

getRowCount in class ListTableMap

Returns:

the number of rows in the model

See Also:

TableModel.getColumnCount()

getValueAt

public Object getValueAt(int rowIndex,
                         int columnIndex)

Returns tableModel.getValueAt

Specified by:

getValueAt in interface TableModel

Overrides:

getValueAt in class ListTableMap

Parameters:

rowIndex - the row whose value is to be queried

columnIndex - the column whose value is to be queried

Returns:

the value Object at the specified cell

isCellEditable

public boolean isCellEditable(int rowIndex,
                              int columnIndex)

Returns false if the row at rowIndex is a grouping row, otherwise returns the value of its super method.

Specified by:

isCellEditable in interface TableModel

Overrides:

isCellEditable in class ListTableMap

Parameters:

rowIndex - the row being queried

columnIndex - the column being queried

Returns:

true if the cell is editable, false otherwise

See Also:

TableModel.setValueAt(java.lang.Object, int, int)

removeRow

public void removeRow(int row)

Removes a row from the data model

Specified by:

removeRow in interface ListTableModel

Overrides:

removeRow in class ListTableMap

Parameters:

row - the index of the row being removed

removeRows

public void removeRows(int[] rows)

Removes a few rows from the data model

Specified by:

removeRows in interface ListTableModel

Overrides:

removeRows in class ListTableMap

Parameters:

rows - an integer array that contains indexes of the rows being deleted

rowsReordered

public void rowsReordered(ReorderEvent e)

Does nothing. Called whenever the rows of a JTable have been restructured.

Specified by:

rowsReordered in interface ReorderListener

Overrides:

rowsReordered in class ListTableMap

Parameters:

e - the ReorderEvent object

setRowComparator

public void setRowComparator(Comparator rowComparator)

Sets the row comparator that will be used to determine row similarity.

Parameters:

rowComparator - the row comparator that we want to use

setValueAt

public void setValueAt(Object aValue,
                       int rowIndex,
                       int columnIndex)

Assigns aValue to the object at columnIndex and rowIndex.

Specified by:

setValueAt in interface TableModel

Overrides:

setValueAt in class ListTableMap

Parameters:

aValue - value to assign to the cell

rowIndex - row of the cell

columnIndex - column of the cell
