## Definition

template<typename T>
class CGAL::Twotuple< T >

The `Twotuple` class stores a homogeneous (same type) pair of objects of type `T`.

A `Twotuple` 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.

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

Template Parameters

  T | must be `Assignable`.

## Types
typedef T | value_type

## Variables
T | e0
| first element
T | e1
| second element

## Creation
| Twotuple ()
| introduces a `Twotuple` using the default constructor of the elements.
| Twotuple (T x, T y)
| constructs a `Twotuple` such that `e0` is constructed from `x` and `e1` is constructed from `y`.
