NAME¶

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

Synopsis¶

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

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 << ' ';
}
