template <class... Args> std::pair<iterator, bool> 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 is called with exactly the same arguments, as supplied to the function.

No iterators or references are 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

Returns a pair consisting of a bool denoting whether the insertion took place and an iterator to the inserted element.

Complexity

Logarithmic in the size of the container in general, but amortized constant if the new element is inserted just before pos.
