std::unorde...emplace_hint(3) C++ Standard Libarystd::unorde...emplace_hint(3) NAME std::unordered_multimap::emplace_hint - std::unordered_multimap::em- place_hint Synopsis template< class... Args > (since C++11) iterator emplace_hint( const_iterator hint, Args&&... args ); Inserts a new element into the container, using hint as a suggestion where the element should go. The constructor of the element type (value_type, that is, std::pair<const Key, T>) is called with exactly the same arguments as supplied to the func- tion, forwarded with std::forward<Args>(args).... If after the operation the new number of elements is greater than old max_load_factor() * bucket_count() a rehashing takes place. If rehashing occurs (due to the insertion), all iterators are inval- idated. Otherwise (no rehashing), iterators are not invalidated. Parameters hint - iterator, used as a suggestion as to where to insert the new element 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 ef- fect (strong exception safety guarantee). Complexity Amortized constant on average, worst case linear in the size of the container.
