std::insert_iterator
Member functions
insert_iterator::operator=
(1)
insert_iterator<Container>&
operator=( typename Container::const_reference value );
(until C++11)
operator=( typename Container::const_reference value );
insert_iterator<Container>&
operator=( const typename Container::value_type& value );
(since C++11) operator=( const typename Container::value_type& value );
(until C++20)
constexpr insert_iterator<Container>&
operator=( const typename Container::value_type& value );
(since C++20)
operator=( const typename Container::value_type& value );
(2)
insert_iterator<Container>&
operator=( typename Container::value_type&& value );
(since C++11) operator=( typename Container::value_type&& value );
(until C++20)
constexpr insert_iterator<Container>&
operator=( typename Container::value_type&& value );
(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;.
Contents
[edit] Parameters
value
-
the value to insert
[edit] 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 ).
[edit] Example
Run this code
#include <deque> #include <iostream> #include <iterator> 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 << ' '; std::cout << '\n'; }
Output:
0 1 2 3 4 5 6 7 8 9
