std::insert_iterator<Container>::operator= – std::insert_iterator<Container>::operator=

Synopsis

insert_iterator<Container> &(until C++ 11)

operator=(typename Container::const_reference value);

insert_iterator<Container> &(since C++ 11)

operator=(const typename Container::value_type &value);
(until C++ 20)

    constexpr insert_iterator<Container> &(1)(since C++ 20)

    operator=(const typename Container::value_type &value);

insert_iterator<Container> &(since C++ 11)

operator=(typename Container::value_type &&value);
(2)(until C++ 20)

    constexpr insert_iterator<Container> &(since C++ 20)

    operator=(typename Container::value_type &&value);
Inserts the given value value to the container.

1) Results in iter = container->insert(iter, value);
++iter;

2) Results in iter = container->insert(iter, std::move(value));
++iter;

Parameters

value – the value to insert

Return value

*this

Notes

This function exploits the signature compatibility between hinted insert for associative containers (such as std::set::insert) and positional insert for sequential containers (such as std::vector::insert).

Example

// Run this code

#include <iostream>

#include <iterator>

#include <deque>
int main()

{
    std::deque<int> q;
    std::insert_iterator<std::deque<int>> it(q, q.begin());
    for (int i = 0; i < 10; ++i)
        it = i; // inserts i
    for (auto &elem : q)
        std::cout << elem << ' ';
}

Output:

0 1 2 3 4 5 6 7 8 9
