There should be little need for future loaders to subclass this, or to implement Scene directly, as the functionality of a SceneBase is fairly straightforward. This class is responsible for both the storage and retrieval of data from the Scene. The storage methods (used only by Loader writers) are all of the add* routines. The retrieval methods (used primarily by Loader users) are all of the get* routines.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!--
