template< class... Args > iterator emplace( Args&&... args );		(since C++11)

Inserts a new element to the container. 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)....

Information on iterator invalidation is copied from here

Parameters

args

-

arguments to forward to the constructor of the element

Return value

returns an iterator to the inserted element.

Complexity

Amortized constant on average, worst case linear in the size of the container.
