std::multimap<Key,T,Compare,Allocator>::emplace_hint
From cppreference.com
template<class... Args> iterator emplace_hint( const_iterator hint, Args&&... args); | (since C++11) | |
Inserts a new element into the container as close as possible to the position just before hint.
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 function, forwarded with std::forward<Args>(args)....
No iterators or references are invalidated.
