std::unordered_multiset::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 is called with exactly the same arguments, as supplied to the function.

If rehashing occurs due to the insertion, all iterators are invalidated. Otherwise iterators are not affected. References are not invalidated. Rehashing occurs only if the new number of elements is higher than max_load_factor()*bucket_count().

Contents

[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 inserted element.

[edit] Complexity

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