std::flat_multiset::emplace(3) C++ Standard Libary std::flat_multiset::emplace(3)

NAME

std::flat_multiset::emplace - std::flat_multiset::emplace

Synopsis


template< class... Args > (since C++23)
iterator emplace( Args&&... args );


Inserts a new element into the container constructed in-place with the given args.


First, initializes an object t of type value_type with std::forward<Args>(args)...,
then inserts t as if by


auto it = ranges::upper_bound(c, t, compare);
c.insert(it, std::move(t));


This overload participates in overload resolution only if
std::is_constructible_v<value_type, Args...> is true.


Careful use of emplace allows the new element to be constructed while avoiding
unnecessary copy or move operations.


Information on iterator invalidation is copied from here

Parameters


args - arguments to forward to the constructor of the element

Return value


An iterator to the inserted element.

Exceptions


If an exception is thrown for any reason, this function has no effect (strong
exception safety guarantee).

Complexity


Logarithmic in the size of the container.
