Package jmri.jmrix.jinput

Class TreeModel

  • All Implemented Interfaces:
    java.io.Serializable, javax.swing.tree.TreeModel
    public final class TreeModel
extends javax.swing.tree.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.

        the default instance of the TreeModel; creating it if necessary
