                                     Object[] path,
                                     int[] childIndices,
                                     Object[] children)

Notifies all listeners that have registered interest for notification on this event type.

getRoot

public Object getRoot()

Returns the root of the tree. Returns null only if the tree has no nodes.

Specified by:

getRoot in interface TreeModel

Returns:

the root of the tree

isAggregate

public boolean isAggregate(Object row)

Determines if node is an aggregate row.

Specified by:

isAggregate in interface TreeTableModel

Parameters:

row - the node to consider

Returns:

true if node is an aggregate row, false otherwise

isFooter

public boolean isFooter(Object row)

Determines if node is a footer.

Specified by:

isFooter in interface TreeTableModel

Parameters:

row - the row to consider

Returns:

true if node is a footer, false otherwise

isHeader

public boolean isHeader(Object row)

Determines if node is a header.

Specified by:

isHeader in interface TreeTableModel

Parameters:

row - the row to query

Returns:

true if node is a header, false otherwise

removeTreeModelListener

public void removeTreeModelListener(TreeModelListener l)

Removes a listener previously added with addTreeModelListener.

Specified by:

removeTreeModelListener in interface TreeModel

Parameters:

l - the listener to remove

See Also:

TreeModel.addTreeModelListener(javax.swing.event.TreeModelListener)

setRoot

public void setRoot(Object newRoot)

Assigns a new root to the model.

Parameters:

newRoot - the new root to assign

fireTreeTableStructureChanged

public void fireTreeTableStructureChanged()

Generates an event that notifies listeners that the whole treetable structure has changed: both row and column data. This event will trigger a structure change TableModelEvent. You can use fireTreeTableStructureChanged(false), if a data change event is to be triggered.

fireTreeTableStructureChanged

public void fireTreeTableStructureChanged(boolean adapterStructureChange)

Generates an event that notifies listeners that the whole treetable structure has changed: both row and column data. The adapterStructureChange argument is significant only if the model is contained within a TreeTableModelAdapter. In this case, using adapterStructureChange with a true value will make TreeTableModelAdapter fire a table structure event.

Parameters:

adapterStructureChange - true if this event will triger a structure change TableModelEvent, false otherwise
