<DL>
<DD>Write <code>universe</code> to the Stream.<p>

 If <code>writeContent</code> is true then all BranchGraphs attached to the
 universe will be saved. If it is false then only the universe
 data structures will be output (PlatformGeometry, ViewerAvatar, Locales,
 and the MultiTransformGroup between the ViewingPlatform and the View).<p>

 If <code>writeContent</code> is true then all the BranchGraphs
 attached to the Locales of the universe must have the
 ALLOW_DETACH capability set. If they do not, a <code>CapabilityNotSetException</code>
 will be thrown<p>

<DL>
<DD>Write the entire graph to the stream.<p>

 The API will correctly handle NodeComponents that are shared
 between seperate graphs. However Nodes cannot be referenced
 in other Graphs.<p>

 If a reference to a Node in another graph is encountered a
 DanglingReferenceException will be thrown.

 <code>namedObjects</code> can contain a mapping between a key and a SceneGraphObject
 in the graph. During the read process this can be used to locate nodes
 in the graph.
