std::unordered_multiset::emplace_hint(3) C++ Standard Libary std::unordered_multiset::emplace_hint(3)

NAME

std::unordered_multiset::emplace_hint - std::unordered_multiset::emplace_hint

Synopsis


template< class... Args > (since C++11)
iterator emplace_hint( const_iterator hint, Args&&... args );


Inserts a new element into the container, using hint as a suggestion where the
element should go.


The constructors of the key and mapped value are called with exactly the same
arguments as supplied to the function, forwarded with std::forward<Args>(args)....


If after the operation the new number of elements is greater than old
max_load_factor() * bucket_count() a rehashing takes place.
If rehashing occurs (due to the insertion), all iterators are invalidated. Otherwise
(no rehashing), iterators are not 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


An iterator to the inserted element.

Exceptions


If an exception is thrown for any reason, this function has no effect (strong
exception safety guarantee).

Complexity


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