## Classes
struct | ValueConverter
| ValueConverter<T>::Type is the type of a LeafNode having the same dimensions as this node but a different value type, T. More...
struct | SameConfiguration
| SameConfiguration<OtherNodeType>::value is `true` if and only if OtherNodeType is the type of a LeafNode with the same dimensions as this node. More...
struct | ValueIter
struct | ChildIter
| Leaf nodes have no children, so their child iterators have no get/set accessors. More...
struct | DenseIter

  This operation modifies only active states, not values. Also, because it can deactivate all of this node's voxels, consider subsequently calling prune.

Note
  This operation modifies only active states, not values. Also note that this operation can result in all voxels being inactive so consider subsequently calling prune.
