std::priority_queue<T,Container,Compare>::emplace - std::priority_queue<T,Container,Compare>::emplace


template< class... Args > (since C++11)
void emplace( Args&&... args );

Pushes a new element to the priority queue. 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.
Effectively calls c.emplace_back(std::forward<Args>(args)...); std::push_heap(c.begin(), c.end(), comp);


args - arguments to forward to the constructor of the element

Return value



Logarithmic number of comparisons plus the complexity of Container::emplace_back.
