30 //
31 // Class description:
32 //
33 // Class for proxying smart voxels. The class represents either a header
34 // (in turn refering to more VoxelProxies) or a node. If created as a node,
35 // calls to GetHeader cause an exception, and likewise GetNode when a header.
36 //
37 // Note that the proxy does NOT gain deletion responsibility for proxied
38 // objects.
39 
40 // History:
41 // 12.07.95 P.Kent Initial version
42 // 03.08.95 P.Kent Updated to become non abstract class, removing
43 // HeaderProxy and NodeProxy derived classes
