The Threetuple<T> class stores a homogeneous (same type) triple of objects of type T. A Threetuple<T> is much like a container, in that it "owns" its elements. It is not actually a model of container, though, because it does not support the standard methods (such as iterators) for accessing the elements of a container.

This class is DEPRECATED, and will be removed in some future CGAL release. Please use CGAL::array instead.

#include <CGAL/Threetuple.h>


T must be Assignable.


typedef T value_type;


T e0; first element
T e1; second element
T e2; third element


Threetuple<T> t;
introduces a Threetuple<T> using the default constructor of the elements.

Threetuple<T> t ( T x, T y, T z);
constructs a Threetuple<T> such that e0 is constructed from x, e1 is constructed from y and e2 is constructed from z.
