Class DynamicTreeBuilder

java.lang.Object
org.cristalise.gui.tree.Node
org.cristalise.gui.DynamicTreeBuilder
All Implemented Interfaces:
Runnable, NodeSubscriber
public class DynamicTreeBuilder extends Node implements NodeSubscriber
Installed as the user object on a single child node of a new node known to be composite.

Shows 'Loading . . .' when the branch is opened, but a TreeExpansionListener attempts to fire this thread off in the first child node.
When started, this thread will retrieve all of the real child nodes and add them to its parent while removing itself (hopefully for garbage collection)
