std::multimap::emplace_hint
From cppreference.com
| template <class... Args>
iterator emplace_hint( const_iterator hint, Args&&... args ); |
(since C++11) | |
Inserts a new element to the container, using hint as a suggestion where the element should go. The element is constructed in-place, i.e. no copy or move operations are performed.
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.

[edit] 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 |
[edit] Return value
Returns an iterator to the newly inserted element.
[edit] Complexity
Logarithmic in the size of the container in general, but amortized constant if the new element is inserted just before hint.
