std::swap(std::priority_queue) 

template< class T, class Container, class Compare >
void swap( priority_queue<T,Container,Compare>& lhs, 
           priority_queue<T,Container,Compare>& rhs );
 (until C++17) 
template< class T, class Container, class Compare >
void swap( priority_queue<T,Container,Compare>& lhs, 
           priority_queue<T,Container,Compare>& rhs ) noexcept(/* see below */);
 (since C++17)

Specializes the std::swap algorithm for std::priority_queue. Swaps the contents of lhs and rhs. Calls lhs.swap(rhs).

This overload only participates in overload resolution if std::is_swappable<Container>::value and std::is_swappable<Compare>::value are both true.

 (since C++17)

Parameters

lhs, rhs - containers whose contents to swap

Return value

(none).

Complexity

Same as swapping the underlying container.

Exceptions

noexcept specification:
noexcept(noexcept(lhs.swap(rhs)))
 (since C++17)
