public class DefaultMutableTreeTableModel
extends ComparableTreeTableModel

DefaultMutableTreeTableModel is a treetable model whose nodes' cell value depends on the aggregate values of a TreeTableRow. The value at each treetable cell is retrieved with TreeTableRow's getAggregateValue method.

Method Summary

protected DefaultMutableTreeNode	createLeafNode(Object o) Creates and returns a new instance of a leaf node whose 'column data' is identified by data.
protected DefaultMutableTreeNode	createNonLeafNode(DefaultMutableTreeNode child) Creates and returns a new instance of a group (non-leaf) node whose child is identified by child.
boolean	getEditable() Determines whether the model is editable.
Object	getValueAt(Object node, int column) Returns the value to be displayed for node, at column index column.
boolean	isCellEditable(Object node, int column) This method is actually a call to getEditable.

Method Detail

createLeafNode

protected DefaultMutableTreeNode createLeafNode(Object o)

Creates and returns a new instance of a leaf node whose 'column data' is identified by data. data in this framework is either DefaultMutableTreeNode's user object attribute or the aggregate values of a TreeTableRow.

Specified by:

createLeafNode in class ComparableTreeTableModel

Parameters:

o - the node's 'column data'.

Returns:

the newly created leaf node.

createNonLeafNode

protected DefaultMutableTreeNode createNonLeafNode(DefaultMutableTreeNode child)

Creates and returns a new instance of a group (non-leaf) node whose child is identified by child.

Specified by:

createNonLeafNode in class ComparableTreeTableModel

Parameters:

child - this node's child (or one of its children)

Returns:

the newly created group (non-leaf) node.

getEditable

public boolean getEditable()

Determines whether the model is editable. If the isCellEditable method is overriden, this method will not truely reflect if the model is editable.

Returns:

true if the model is editable, false otherwise.

getValueAt

public Object getValueAt(Object node,
                         int column)

Returns the value to be displayed for node, at column index column.

Parameters:

node - the node to query

column - the column index

Returns:

the value

isCellEditable

public boolean isCellEditable(Object node,
                              int column)

This method is actually a call to getEditable. Returns true if node at columnIndex is editable.

Specified by:

isCellEditable in interface TreeTableModel

Overrides:

isCellEditable in class MutableTreeTableModel

Parameters:

node - the node to consider

column - the column index

Returns:

true if the node at columnIndex is editable, false otherwise

replicateLeafNode

protected DefaultMutableTreeNode replicateLeafNode(DefaultMutableTreeNode child)

Creates and returns a new instance of the leaf node identified by child. This method is used when the underlying comparators have changed, so that the tree can be restructured.

Specified by:

replicateLeafNode in class ComparableTreeTableModel

Parameters:

child - the leaf we want to create a replica of.

Returns:

the newly created leaf node.

setEditable

public void setEditable(boolean editable)

Makes the model editable/non-editable.

Parameters:

editable - true, should the model be editable, false otherwise.

setValueAt

public void setValueAt(Object value,
                       Object node,
                       int column)

Sets the value for node at columnIndex to aValue.

Specified by:

setValueAt in interface TreeTableModel

Overrides:

setValueAt in class MutableTreeTableModel

Parameters:

value - the new value

node - the node whose value is to be changed

column - the column whose value is to be changed
