public class DefaultRemoteTreeTableModel
extends TreeModelMap
implements RemoteTreeTableModel

DefaultRemoteTreeTableModel is the default implementation of a RemoteTreeTableModel. This class wraps around a cacheable treetable model and uses an internal thread in order to asynchronously retrieve the data from the underlying model.

Constructor Summary

DefaultRemoteTreeTableModel(CacheableTreeTableModel model)
Constructs a DefaultRemoteTreeTableModel.

Method Summary

void	addRemoteTableListener(RemoteTableListener l) Adds a RemoteTableListener that is notified each time the RemoteTableModel will start or stop querying the underlying treetable model.
void	fireRemoteAction(int type) Notifies listeners of this RemoteTreeTableModel's status.
int	getChildCount(Object parent) Returns the number of children of parent. Returns 0 if the node is a leaf or if it has no children. parent must be a node previously obtained from this data source.
Class	getColumnClass(int column) Returns the class of all the cells in the column.
int	getColumnCount() Returns the number of columns.
String	getColumnName(int column) Returns the name of the column at columnIndex as it will be displayed by the table
Object	getPendingValue(Object node, int column) Returns the object to display if a cell value is pending.
Object	getValueAt(Object node, int column) Returns the value to be displayed for node, at column index column.
boolean	isCellEditable(Object node, int column) Returns true if node at columnIndex is editable.
void	removeRemoteTableListener(RemoteTableListener l) Removes a RemoteTableListener from the list that is notified each time the RemoteTableModel will start or stop querying the underlying treetable model.
void	setTreeModel(TreeModel newModel) Sets the underlying tree model to newModel
void	setValueAt(Object aValue, Object node, int column) Sets the value for node at columnIndex to aValue.
void	stop() Stops the thread that asynchronously queries the underlying cacheable treetable model.

Constructs a DefaultRemoteTreeTableModel.

Method Detail

addRemoteTableListener

public void addRemoteTableListener(RemoteTableListener l)

Notifies listeners of this RemoteTreeTableModel's status.

Parameters:

type - the type of the event - either STARTED or STOPPED.

getChildCount

public int getChildCount(Object parent)

Returns the number of children of parent. Returns 0 if the node is a leaf or if it has no children. parent must be a node previously obtained from this data source.

Specified by:

getChildCount in interface TreeModel

parent - a node in the tree, obtained from this data source

Returns:

the number of children of the node parent

getColumnClass

public Class getColumnClass(int column)

the class of all the cells in the column.

getColumnCount

public int getColumnCount()

Returns the number of columns.

Specified by:

getColumnCount in interface TreeTableModel

Specified by:

getPendingValue in interface RemoteTreeTableModel

Parameters:

node - the node to consider

column - the node's column index

Returns:
