reverse

Synopsis

template<
      typename Sequence
    >
struct reverse
{
    typedef implementation-defined type;
};

Description

Reverses a sequence. The result sequence preserves all the functional and performance characteristics of the original Sequence, including its size, but not identity.

Definition

#include "boost/mpl/reverse.hpp"

Parameters

Expression semantics

Expression	Expression type	Precondition	Semantics	Postcondition
typedef reverse<Sequence>::type s;	A model of Extensible Sequence			size<s>::type::value == size<Sequence>::type::value.

Complexity

Linear.

Example

typedef list_c<int,9,8,7,6,5,4,3,2,1,0>::type numbers;
typedef reverse< numbers >::type result;

typedef range_c<int,0,10> answer;
BOOST_STATIC_ASSERT((equal<result,answer>::type::value));
