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

Creation
	Interval ()
	Default constructor.

Types
typedef unspecified_type	Value
	The type of the lower and upper bound of the interval.

Access Functions
Value	inf () const
	Returns the lower bound.
Value	sup () const
	Returns the upper bound.
bool	contains (const Value &v) const
	Returns true, iff the interval contains v.
bool	contains_interval (const Value &i, const Value &s) const
	Returns true, iff the interval contains (i,s).
bool	operator== (const Interval &I) const
	Equality test.
bool	operator!= (const Interval &I) const
	Inequality test.
