The Segment Concept describes the requirements for a segment type. All algorithms in Boost.Geometry will check any geometry arguments against the concept requirements.
traits::tag
defining segment_tag
as type
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)
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)

The segment concept is similar to the box concept, defining using another
tag. However, the box concept assumes the index as |
