template<class...Args> iterator emplace( Args&&...args); | (since C++23) (constexpr since C++26) | |
Inserts a new element into the container constructed in-place with the givenargs.
First, initializes an objectt of typevalue_type withstd::forward<Args>(args)..., then insertst as if byauto it=ranges::upper_bound(c, t, compare);c.insert(it, std::move(t));
This overload participates in overload resolution only ifstd::is_constructible_v<value_type, Args...> istrue.
Ifvalue_type is notEmplaceConstructible intoflat_multiset fromargs, the behavior is undefined.

An iterator to the inserted element.
If an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).
Logarithmic in the size of the container.
Careful use ofemplace allows the new element to be constructed while avoiding unnecessary copy or move operations.
