std::flat_multiset
flat_multiset::emplace
template< class... Args >
iterator emplace( Args&&... args );
(since C++23) iterator emplace( Args&&... args );
(constexpr since C++26)
Inserts a new element into the container constructed in-place with the given args.
First, initializes an object t of typevalue_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.
If value_type
is not EmplaceConstructible into flat_multiset
from args, the behavior is undefined.
Information on iterator invalidation is copied from here
[edit] Parameters
args
-
arguments to forward to the constructor of the element
[edit] Return value
An iterator to the inserted element.
[edit] Exceptions
If an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).
[edit] Complexity
Logarithmic in the size of the container.
[edit] Notes
Careful use of emplace
allows the new element to be constructed while avoiding unnecessary copy or move operations.
