updateNodeReferences</H3>
<PRE>
public void <B>updateNodeReferences</B>(<A HREF="../../../javax/media/j3d/NodeReferenceTable.html">NodeReferenceTable</A>&nbsp;referenceTable)</PRE>
<DL>
<DD>Callback used to allow a node to check if any scene graph objects
 referenced
 by that node have been duplicated via a call to <code>cloneTree</code>.
 This method is called by <code>cloneTree</code> after all nodes in
 the sub-graph have been duplicated. The cloned Leaf node's method
 will be called and the Leaf node can then look up any object references
 by using the <code>getNewObjectReference</code> method found in the
 <code>NodeReferenceTable</code> object.  If a match is found, a
 reference to the corresponding object in the newly cloned sub-graph
 is returned.  If no corresponding reference is found, either a
 DanglingReferenceException is thrown or a reference to the original
 object is returned depending on the value of the
 <code>allowDanglingReferences</code> parameter passed in the
 <code>cloneTree</code> call.
 <p>
 NOTE: Applications should <i>not</i> call this method directly.
 It should only be called by the cloneTree method.
