Class IlvTreeListToTreeModel

java.lang.Object

ilog.views.chart.datax.adapter.IlvTreeListToTreeModel

All Implemented Interfaces:

Cloneable, TreeModel

Direct Known Subclasses:

IlvTreeListToTreeTableModel

public class IlvTreeListToTreeModel
extends Object
implements TreeModel, Cloneable

This class implements a Swing TreeModel, based on an IlvTreeListModel.

Note: This model does not support adding and removing objects. You should use the underlying IlvTreeListModel for this purpose (assuming it is an instance of IlvDefaultTreeListModel).

Since:

JViews 7.5

Constructor Detail

IlvTreeListToTreeModel

public IlvTreeListToTreeModel(IlvTreeListModel model)

Creates a model backed by a given IlvTreeListModel.

Parameters:

model - An IlvTreeListModel.

Method Detail

addTreeModelListener

public void addTreeModelListener(TreeModelListener listener)

Specified by:

addTreeModelListener in interface TreeModel

removeTreeModelListener

public void removeTreeModelListener(TreeModelListener listener)

Specified by:

removeTreeModelListener in interface TreeModel

getRoot

public Object getRoot()

Specified by:

getRoot in interface TreeModel

getChild

public Object getChild(Object parent,
                       int index)

Specified by:

getChild in interface TreeModel

getChildCount

public int getChildCount(Object parent)

Specified by:

getChildCount in interface TreeModel

isLeaf

public boolean isLeaf(Object node)

This method returns true if and only if the node has no children. It should be overridden in subclasses if there are nodes without children that are not leaves.

Specified by:

isLeaf in interface TreeModel

valueForPathChanged

public void valueForPathChanged(TreePath path,
                                Object newValue)

This method does nothing. It should be overridden in subclasses to achieve the desired side effect in the underlying model.

Specified by:

valueForPathChanged in interface TreeModel

Parameters:

path - Path to the node that the user has altered.

newValue - The new value from the TreeCellEditor.

getIndexOfChild

public int getIndexOfChild(Object parent,
                           Object child)

Specified by:

getIndexOfChild in interface TreeModel

getColumnCount

public int getColumnCount()

Returns the number of available columns.

getColumnName

public String getColumnName(int columnIndex)

Returns the name for column number columnIndex.

getColumnClass

public Class getColumnClass(int columnIndex)

Returns the type for column number columnIndex.

getValueAt

public Object getValueAt(Object node,
                         int columnIndex)

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

setValueAt

public void setValueAt(Object newValue,
                       Object node,
                       int columnIndex)

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

isCellEditable

public boolean isCellEditable(Object node,
                              int columnIndex)

Indicates whether the value for node node, at column number columnIndex is editable. This default implementation always returns false.

noteDataChanged

protected void noteDataChanged(Object object,
                               TreePath objectPath,
                               boolean recursive,
                               int column)

This method is called when the values for some objects and some columns have changed in the underlying model. It can be extended in subclasses.

noteObjectsChanged

protected void noteObjectsChanged(Object parent,
                                  TreePath parentPath,
                                  Object[] oldObjects,
                                  Object[] newObjects,
                                  int firstIndex)

This method is called when some objects (rows) have been added or removed in the underlying model. It can be extended in subclasses.

noteColumnAdded

protected void noteColumnAdded(int column,
                               IlvDataColumnInfo columnInfo)

This method is called when a column has been added to the underlying model. It can be extended in subclasses.

noteColumnRemoved

protected void noteColumnRemoved(int column,
                                 IlvDataColumnInfo columnInfo)

This method is called when a column has been removed from the underlying model. It can be extended in subclasses.

noteColumnPropertyChanged

protected void noteColumnPropertyChanged(TreeListModelEvent.Type type,
                                         int column,
                                         Object oldValue,
                                         Object newValue)

This method is called when column properties have changed in the underlying model. It can be extended in subclasses.

getUnderlyingModel

public IlvTreeListModel getUnderlyingModel()

Returns the underlying model.

Returns:

The IlvTreeListModel passed to the constructor.

dispose

public void dispose()

Cleans up this model and drops references to objects to help garbage collection.

Note: After calling this function, this model is no longer functional.

disconnect

public void disconnect()

Drops references to objects to help garbage collection.

Note: After calling this function, and after some changes occurred in the underlying model, this model is no longer functional.

JViews 8.0

clone

public Object clone()

Returns a copy of this object.

Overrides:

clone in class Object
