Interval Concept Reference

Definition

The concept Interval describes the requirements for the template argument Interval of a Interval_skip_list<Interval>.

The concept does not specify, whether the interval is open or closed. It is up to the implementer of a model for this concept to define that.

Has Models:

CGAL::Interval_skip_list_interval<Value>

CGAL::Level_interval

See also

Interval_skip_list

Examples:

Interval_skip_list/intervals.cpp, and Interval_skip_list/isl_terrain.cpp.
