Defined in header <iterator>
template <class Iterator> class move_iterator		(desde C++11)

std::move_iterator iterador es un adaptador que se comporta exactamente igual que el iterador subyacente (que debe ser de al menos un InputIterator), excepto que desreferencia convierte el valor devuelto por el iterador subyacente en un valor p. Si este iterador se utiliza como un iterador de entrada, el efecto es que los valores se desplazan de, en lugar de copiado de .

Original:

std::move_iterator is an iterator adaptor which behaves exactly like the underlying iterator (which must be at least an InputIterator), except that dereferencing converts the value returned by the underlying iterator into an rvalue. If this iterator is used as an input iterator, the effect is that the values are moved from, rather than copied from.

Ejemplo

#include <iostream>
#include <algorithm>
#include <vector>
#include <iterator>
#include <numeric>
int main()
{
    std::vector<std::string> v{"this", "is", "an", "example"};
 
    std::cout << "Old contents of the vector: ";
    for(auto& s : v)
        std::cout << '"' << s << "\" ";
 
    typedef std::vector<std::string>::iterator iter_t;
    std::string concat = std::accumulate(
                             std::move_iterator<iter_t>(v.begin()),
                             std::move_iterator<iter_t>(v.end()),
                             std::string());  // Can be simplified with std::make_move_iterator
 
    std::cout << "\nConcatenated as string: " << concat << '\n'
              << "New contents of the vector: ";
    for(auto& s : v)
        std::cout << '"' << s << "\" ";
    std::cout << '\n';
}

Output:

Old contents of the vector: "this" "is" "an" "example"
Concatenated as string: thisisanexample
New contents of the vector: "" "" "" ""
