* \ingroup PkgAABB_tree
|
|
* Primitive type that uses as identifier an iterator with a 3D segment as `value_type`.
|
|
* The iterator from which the primitive is built should not be invalided
|
|
* while the AABB tree holding the primitive is in use.
|

*
|
|
* \cgalModels `AABBPrimitive`
|
|
*
|
|
* \tparam GeomTraits is a traits class providing the nested type `Point_3` and `Segment_3`.
|
|
* It also provides the functor `Construct_source_3` that has an operator taking a `Segment_3`
|
|
* and returning its source as a type convertible to `Point_3`.
|
|
* In addition `Construct_source_3` must support the result_of protocol.
|
|
* \tparam Iterator is a model of `ForwardIterator` with its value type convertible to `GeomTraits::Segment_3`
|
|
* \tparam CacheDatum 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).
