* \ingroup PkgAABB_tree
|
|
* The class AABB_segment_primitive is a model of the concept `AABBPrimitive`.
|
|
* An iterator with a 3D segment as `value_type}` is used as identifier.
|
|
* The iterator from which the primitive is built should not be invalided
|
|
* while the AABB tree holding the primitive is in use.
|
|
*
|
|
* \tparam Iterator is a model of `ForwardIterator`, with `Segment_3<Kernel>`
|
|
* as value type
|
|
* \tparam cache_datum is either `CGAL::Tag_true` or `CGAL::Tag_false`. In the former case,
|
|
* the datum is stored in the primitive, while in the latter it is
|
|
* constructed on the fly to reduce the memory footprint.
|
|
* The default is `CGAL::Tag_false` (datum is not stored).
