constexpr insert_iterator<Container>& 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
