std::unordered_multiset::emplace
From cppreference.com
< cpp | container | unordered multiset
template< class... Args > iterator emplace( Args&&... args ); |
(since C++11) | |
Inserts a new element to the container. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element is called with exactly the same arguments, as supplied to the function, forwarded with std::forward<Args>(args)....
If rehashing occurs due to the insertion, all iterators are invalidated. Otherwise iterators are not affected. References are not invalidated. Rehashing occurs only if the new number of elements is equal to or greater than max_load_factor()*bucket_count().

[edit] Complexity
Amortized constant on average, worst case linear in the size of the container.
