NAME¶

std::front_insert_iterator::operator= - std::front_insert_iterator::operator=

Synopsis¶

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

Inserts the given value value to the container.

1) Results in container->push_front(value).
2) Results in container->push_front(std::move(value)).

Parameters¶

value - the value to insert

Return value¶

*this

Example¶

// Run this code

#include <deque>
#include <iostream>
#include <iterator>

int main()
{
std::deque<int> q;
std::front_insert_iterator<std::deque<int>> it(q);

for (int i = 0; i < 10; ++i)
it = i; // calls q.push_front(i)

for (auto& elem : q)
std::cout << elem << ' ';
std::cout << '\n';
}
