- [section:concept_segment Segment Concept]
- [heading Description]
- [concept Segment..segment]
- [heading Concept Definition]
- * there must be a specialization of `traits::tag` defining `segment_tag` as type
- * there must be a specialization of `traits::point_type` to define the underlying point type
- (even if it does not consist of points, it should define this type, to indicate the points it can work with)
- * there must be a specialization of `traits::indexed_access`, per index and per dimension, with two functions:
- * `get` to get a coordinate value
- * `set` to set a coordinate value (this one is not checked for ConstSegment)
-
- [note The segment concept is similar to the box concept, defining using another tag.
- However, the box concept assumes the index as `min_corner`, `max_corner`, while for the segment concept, there is no assumption.]
