Constructor Summary

TVModel(TreeViewer treeViewer)
Construct a TVModel, which includes both the hierarchial and type-based views.

Method Summary

void	create() Explicitly create the models.
protected void	createModelsFromData() Creates two models (type & hierarchy) from 1 data set.
int	getModelType() Returns the model type currently displayed; is either BY_HIERARCHY or BY_TYPE.
void	setModelType(int value) Select which model to display; we have a choice of BY_HIERARCHY or BY_TYPE.
void	valueForPathChanged(javax.swing.tree.TreePath path, java.lang.Object newValue) This method should be called any time a node has been altered.

Constructor Detail

TVModel

public TVModel(TreeViewer treeViewer)

Construct a TVModel, which includes both the hierarchial and type-based views. The models are not created until the create() method is called.

Parameters:

treeViewer - A reference to the TreeViewer instance.

Method Detail

create

public void create()

Explicitly create the models.

setModelType

public void setModelType(int value)

Select which model to display; we have a choice of BY_HIERARCHY or BY_TYPE.

Parameters:

value - Model type to display.

getModelType

public int getModelType()

Returns the model type currently displayed; is either BY_HIERARCHY or BY_TYPE.

valueForPathChanged

public void valueForPathChanged(javax.swing.tree.TreePath path,
                                java.lang.Object newValue)

This method should be called any time a node has been altered.

Overrides DefaultModel valueForPathChanged(), and provides filtering support for items that have changed.

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

Overrides:

valueForPathChanged in class javax.swing.tree.DefaultTreeModel

createModelsFromData

protected void createModelsFromData()

Creates two models (type & hierarchy) from 1 data set. Note that this uses the example data; in 'real life' we would use data from the Universe database.

TVData objects are shared between models.
