从eclipse插件动态更新TreeViewer

Question

I am creating a eclipse plugin which requires TreeViewer to be dynamically updated when domain object changes.

I have found one article from eclipse site

http://www.eclipse.org/articles/Article-TreeViewer/TreeViewerArticle.htm?PHPSESSID=4d48764999a9cb66a7fd58a954ef2131

This article mentions below code to register for domain object changes

/** Because the domain model does not have a richer
 * listener model, recursively add this listener
 * to each child box of the given box. */
protected void addListenerTo(MovingBox box) {
    box.addListener(this);
    for (Iterator iterator = box.getBoxes().iterator(); iterator.hasNext();) {
       MovingBox aBox = (MovingBox) iterator.next();
       addListenerTo(aBox);
    }
}

It mentions addListener method of MovingBox which is supposedly the domain object in this case. The article does not provide any code samples for MovingBox implementation. I am facing lot of difficulty in understanding where addListener method came from?

I have searched a lot on web to find any working example of Treeview which can get dynamically updated on domain changes. Not sure if I am searching for right thing. Can someone please help me regarding the same?

All the source code for this TreeViewer example is available in the link given in the 'Source Code' section at the start of the article.
