 * data tree. Internal routines of the TE topology manager may use the
 * following example methods to construct and manipulate any piece of data in
 * the data tree:
 * <pre>
 * newNode.getTe().setAdminStatus(), or
 * newNode.getSupportingNodeIds().add(nodeId), etc.
 * </pre>
 * Same for constructors where, for example, a child list may be constructed
 * first and passed in by reference to its parent object constructor.
