std::multiset emplace_hint() method

// Non const version only
template <class... Args>
iterator emplace_hint( const_iterator hint, Args&&... args );

Inserts a new element to the container as close as possible to the position just before hint. 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)....

note

No iterators or references are invalidated.

Parameters​

  • hint - iterator to the position before which the new element will be inserted
  • args - arguments to forward to the constructor of the element

Return value​

Returns an iterator to the newly inserted element.

Complexity​

Logarithmic in the size of the container in general - O(log size()).
Amortized constant if the new element is inserted just before hint - O(1).

Exceptions​

If an exception is thrown by any operation, this function has no effect (strong exception guarantee).
