This is an abstract class for any volume in any sense which can be said to define the locality of reference of a node in a graph, along with all of its descendants.
It is not necessarily a geometric volume (although see GeometricBoundingVolume); this is simply an abstract interface for bounds of any sort.
enum BoundsType 
enum IntersectionFlags 
int contains  (  const BoundingVolume  vol  ) 
Returns the appropriate set of IntersectionFlags to indicate the amount of intersection with the indicated volume.
bool extendBy  (  const BoundingVolume  vol  ) 
Increases the size of the volume to include the given volume.

bool isEmpty  (  ) 
Any kind of volume might be empty.
This is a degenerate volume that contains no points; it's not the same as, for instance, a sphere with radius zero, since that contains one point (the center). It intersects with no other volumes.
bool isInfinite  (  ) 
The other side of the empty coin is an infinite volume.
This is a degenerate state of a normally finite volume that contains all points. (Note that some kinds of infinite bounding volumes, like binary separating planes, do not contain all points and thus correctly return is_infinite() == false, even though they are technically infinite. This is a special case of the word 'infinite' meaning the volume covers all points in space.)
It completely intersects with all other volumes except empty volumes.
BoundingVolume makeCopy  (  ) 
output  (  Ostream  out  ) 
setInfinite  (  ) 
Marks the volume as infinite, even if it is normally finite.
You can think of this as an infinite extend_by() operation.
