### reverse_view

`reverse_view` presents a reversed view of underlying sequence. The first element will be its last and the last element will be its first.

#### Header

    #include <boost/fusion/view/reverse_view.hpp>
    #include <boost/fusion/include/reverse_view.hpp>

#### Synopsis

    template <typename Sequence>
    struct reverse_view;

#### Template parameters

Parameter | Description | Default
--- | --- | ---
`Sequence` | A Bidirectional Sequence |

#### Model of

- Bidirectional Sequence

Notation

`RV`

  A `reverse_view` type

`s`

  An instance of `Sequence`

`rv`, `rv2`

  Instances of `reverse_view`

#### Expression Semantics

Semantics of an expression is defined only where it differs from, or is not defined in Bidirectional Sequence.

Expression | Semantics
--- | ---
`RV(s)` | Creates a unary `reverse_view` given sequence, `s`.
`RV(rv)` | Copy constructs a `reverse_view` from another `reverse_view`, `rv`.
`rv = rv2` | Assigns to a `reverse_view`, `rv`, from another `reverse_view`, `rv2`.

#### Example

    typedef vector<int, short, double> vector_type;
    vector_type vec(2, 5, 3.3);

    reverse_view<vector_type> reverse(vec);
    std::cout << reverse << std::endl;
