std::insert_iterator<Container>::operator=

(1) 
insert_iterator<Container>&
    operator=( typename Container::const_reference value );
 (until C++11) 
insert_iterator<Container>&
    operator=( const typename Container::value_type& value );
 (since C++11)
(until C++20) 
constexpr insert_iterator<Container>&
    operator=( const typename Container::value_type& value );
 (since C++20)
(2) 
insert_iterator<Container>&
    operator=( typename Container::value_type&& value );
 (since C++11)
(until C++20) 
constexpr insert_iterator<Container>&
    operator=( typename Container::value_type&& value );
 (since C++20)

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

#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
