|

| 34 | // Class for proxying smart voxels. The class represents either a header
|
|---|
| 35 | // (in turn refering to more VoxelProxies) or a node. If created as a node,
|
|---|
| 36 | // calls to GetHeader cause an exception, and likewise GetNode when a header.

| 37 | //
|

| 38 | // Note that the proxy does NOT gain deletion responsibility for proxied
|
|---|
| 39 | // objects.
