public class IlvTreeTableToTreeListModel
extends IlvDefaultTreeListModel

This class implements an IlvTreeListModel, based on a TreeTableModel.

There are multiple equivalent variants of TreeTableModel, such as the original TreeTableModel from Sun, the JDNC org.jdesktop.swing.treetable.TreeTableModel from Sun, ilog.webui.dhtml.components.IlxWTreeTableModel (part of Rogue Wave JTGO), the Mozilla org.mozilla.javascript.tools.debugger.TreeTableModel.

Note: This model does not support adding and removing objects. You should use the underlying TreeTableModel for this purpose (assuming it is an instance of DefaultTreeModel and its nodes are instances of MutableTreeNode).

JViews 7.5

Sets the value for node node, at column number column.

getRoot

public Object getRoot()

Returns the root object in this model, or null if the model is empty.

Specified by:

getRoot in interface IlvTreeListModel

Overrides:

getRoot in class IlvDefaultTreeListModel

getChildren

public List getChildren(Object parent)

Returns the children objects of a given object in this model.

Specified by:

getChildren in interface IlvTreeListModel

Overrides:

getChildren in class IlvDefaultTreeListModel

Returns:

An unmodifiable list.

getPath

public TreePath getPath(Object object)

Returns the path from the root to the given object.

Specified by:

getPath in interface IlvTreeListModel

Overrides:

getPath in class IlvDefaultTreeListModel

Parameters:

object - An object in the model.

Returns:

A TreePath whose first component is getRoot() and whose last component is the given object.

getValueAt

public Object getValueAt(Object object,
                         int columnIndex)

Returns the value for the attribute number columnIndex in the given object.

Specified by:

getValueAt in interface IlvObjectModelWithColumns

Specified by:

getValueAt in interface IlvTreeListModel

Overrides:

getValueAt in class IlvDefaultTreeListModel

Parameters:

object - The object (row) in which the value is to be looked up.

columnIndex - The column denoting the attribute whose value is to be looked up.

getDoubleAt

public double getDoubleAt(Object object,
                          int columnIndex)

Returns the value for the attribute number columnIndex in the given object.

This method should only be used for columns whose type is Double. For other types of columns, this method will do a conversion from the object returned by getValueAt, which may be inefficient or inaccurate or raise exceptions.

Specified by:

getDoubleAt in interface IlvObjectModelWithColumns

Specified by:

getDoubleAt in interface IlvTreeListModel

Overrides:

getDoubleAt in class IlvDefaultTreeListModel

Parameters:

object - The object (row) in which the value is to be looked up.

columnIndex - The column denoting the attribute whose value is to be looked up.

setValueAtInternal

protected boolean setValueAtInternal(Object value,

                                     boolean forReal)

Does the equivalent of a setValueAt(). Instead of notifying it simply returns a boolean indicating whether notification should be done.

If forReal is false, the value is not actually set, but the method still returns the same Boolean, indicating whether the given value is different from the previous one.

Overrides:

setValueAtInternal in class IlvDefaultTreeListModel

setDoubleAtInternal

protected boolean setDoubleAtInternal(double value,
                                      Object object,

                                      boolean forReal)

Does the equivalent of a setDoubleAt(). Instead of notifying it simply returns a boolean indicating whether notification should be done.

If forReal is false, the value is not actually set, but the method still returns the same Boolean, indicating whether the given value is different from the previous one.

Overrides:

setDoubleAtInternal in class IlvDefaultTreeListModel

isColumnComputed

protected boolean isColumnComputed(int columnIndex)

Returns true if setValueAtInternal and setDoubleAtInternal have no effect on a given column.

Overrides:

isColumnComputed in class IlvBasicTreeListModel

getSupportedEventsMask

public int getSupportedEventsMask()

Returns a bit mask denoting the optional kinds of events that are guaranteed to be sent by this model to the registered listeners.

This implementation returns DURING_OBJECTS_REMOVED_MASK | BEFORE_COLUMN_REMOVED_MASK, intersected with the eventsMaskHint constructor argument. It may need to be overridden in subclasses.

Specified by:

getSupportedEventsMask in interface IlvTreeListModel

Overrides:

getSupportedEventsMask in class IlvDefaultTreeListModel
