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.

#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

A model of Bidirectional Sequence if Sequence is a Bidirectional Sequence else, Random Access Sequence if Sequence is a Random Access Sequence.
Associative Sequence if Sequence implements the Associative Sequence model.

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 the implemented models.

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;
