[−][src]Trait broccoli::node::Aabb
Trait to signify that this object has an axis aligned bounding box.
Multiple calls to Aabb::get()
must return a aabb with the same value.
This is hard for the user not to do since the user
does not have &mut self
,
but it is still possible through the use of static objects or RefCell
/ Mutex
, etc.
Using these type of methods the user could make different calls to get()
return different aabbs.
This is unsafe since we allow query algorithms to assume the following:
If two object's aabb's don't intersect, then they can be mutated at the same time.
