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