NAME¶
std::multiset::emplace_hint - std::multiset::emplace_hint
Synopsis¶
template <class... Args> (since C++11)
iterator emplace_hint( const_iterator hint, Args&&... args );
Inserts a new element to the container as close as possible to the position
just
before hint. 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, 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¶
Returns an iterator to the newly inserted element.
Exceptions¶
If an exception is thrown by any operation, this function has no
effect (strong
exception guarantee).
Complexity¶
Logarithmic in the size of the container in general, but
amortized constant if the
new element is inserted just before hint.
