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

Pushes 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);

Contents

Parameters

args - arguments to forward to the constructor of the element
