std::move_iterator::operator*

reference operator*() const;
Dereference iterator
Returns an rvalue reference to the element pointed by the iterator.

Internally, the function returns the result of dereferencing its base iterator casted to the appropriate rvalue reference type.

The iterator shall point to some object in order to be dereferenceable.

Parameters

none

Return value

An rvalue reference to the element pointed by the iterator.
Member type reference is an alias of the rvalue reference type that refers to base iterator's own value type.

// move_iterator::operator* example
#include <iostream>     // std::cout
#include <iterator>     // std::move_iterator
#include <vector>       // std::vector
#include <string>       // std::string

int main () {
  std::string str[] = {"one","two","three"};
  std::vector<std::string> foo;

  std::move_iterator<std::string*> it (str);
  for (int i=0; i<3; ++i) {
    foo.push_back(*it);
    ++it;
  }

  std::cout << "foo:";
  for (std::string& x : foo) std::cout << ' ' << x;
  std::cout << '\n';

  return 0;
}


Output:

foo: one two three

Data races

The object is accessed.
The reference returned can be used to access or modify elements.

Exception safety

Provides the same level of guarantee as the operations internally applied to the base iterator.
