Class TreeModel

Show UML class diagram

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 Detail

insertNode

DefaultMutableTreeNode insertNode(DefaultMutableTreeNode pChild,
                                  DefaultMutableTreeNode pParent)

Add a node to the tree if it doesn't already exist

Parameters:

pChild - Node to possibly be inserted; relies on equals() to avoid duplicates

pParent - Node for the parent of the resource to be scanned, e.g. where in the tree to insert it.

Returns:

node, regardless of whether needed or not

instance

public static TreeModel instance()

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

controllers

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

loadSystem

void loadSystem()

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)
