NAME¶

std::multimap::emplace_hint - std::multimap::emplace_hint

Synopsis¶

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

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

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)....

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¶

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¶

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