Package jmri.jmrix.jinput

Class TreeModel

java.lang.Object

javax.swing.tree.DefaultTreeModel

jmri.jmrix.jinput.TreeModel

All Implemented Interfaces:

Serializable, TreeModel

public final class TreeModel
extends DefaultTreeModel

TreeModel represents the USB controllers and components

Accessed via the instance() member, as we expect to have only one of these models talking to the USB subsystem.

The tree has three levels below the uninteresting root:

1. USB controller
2. Components (input, axis)

jinput requires that there be only one of these for a given USB system in a given JVM so we use a pseudo-singlet "instance" approach

Class is final because it starts a survey thread, which runs while constructor is still active.

Method Details

instance

public static TreeModel instance()

Provide access to the model. There's only one, because access to the USB subsystem is required.

Returns:

the default instance of the TreeModel; creating it if necessary

terminateThreads

public void terminateThreads()
                      throws InterruptedException

Throws:

InterruptedException

controllers

public net.java.games.input.Controller[] controllers()

loadSystem

boolean loadSystem()

Returns:

true for success

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)
