If uses_allocator_v<container_type, Alloc> is false the constructors in this subclause shall not participate in overload resolution.

🔗

template<class Alloc> constexpr explicit priority_queue(const Alloc& a);

Effects: Initializes c with a and value-initializes comp.

🔗

template<class Alloc> constexpr priority_queue(const Compare& compare, const Alloc& a);

Effects: Initializes c with a and initializes comp with compare.

🔗

template<class Alloc>
  constexpr priority_queue(const Compare& compare, const Container& cont, const Alloc& a);

Effects: Initializes c with cont as the first argument and a as the second argument, and initializes comp with compare; calls make_heap(c.begin(), c.end(), comp).

🔗

template<class Alloc>
  constexpr priority_queue(const Compare& compare, Container&& cont, const Alloc& a);

Effects: Initializes c with std::move(cont) as the first argument and a as the second argument, and initializes comp with compare; calls make_heap(c.begin(), c.end(), comp).

🔗

template<class Alloc> constexpr priority_queue(const priority_queue& q, const Alloc& a);

Effects: Initializes c with q.c as the first argument and a as the second argument, and initializes comp with q.comp.

🔗

template<class Alloc> constexpr priority_queue(priority_queue&& q, const Alloc& a);

Effects: Initializes c with std::move(q.c) as the first argument and a as the second argument, and initializes comp with std::move(q.comp).

🔗

template<class InputIterator, class Alloc>
  constexpr priority_queue(InputIterator first, InputIterator last, const Alloc& a);

Effects: Initializes c with first as the first argument, last as the second argument, and a as the third argument, and value-initializes comp; calls make_heap(c.begin(), c.end(), comp).

🔗

template<class InputIterator, class Alloc>
  constexpr priority_queue(InputIterator first, InputIterator last,
                           const Compare& compare, const Alloc& a);

Effects: Initializes c with first as the first argument, last as the second argument, and a as the third argument, and initializes comp with compare; calls make_heap(c.begin(), c.end(), comp).

🔗

template<class InputIterator, class Alloc>
  constexpr priority_queue(InputIterator first, InputIterator last, const Compare& compare,
                           const Container& cont, const Alloc& a);

Effects: Initializes c with cont as the first argument and a as the second argument, and initializes comp with compare; calls c.insert(c.end(), first, last); and finally calls make_heap(c.begin(), c.end(), comp).

🔗

template<class InputIterator, class Alloc>
  constexpr priority_queue(InputIterator first, InputIterator last, const Compare& compare,
                           Container&& cont, const Alloc& a);

Effects: Initializes c with std::move(cont) as the first argument and a as the second argument, and initializes comp with compare; calls c.insert(c.end(), first, last); and finally calls make_heap(c.begin(), c.end(), comp).

🔗

template<container-compatible-range<T> R, class Alloc>
  constexpr priority_queue(from_range_t, R&& rg, const Compare& compare, const Alloc& a);

Effects: Initializes comp with compare and c with ranges::to<Container>(std::forward<R>(rg), a); calls make_heap(c.begin(), c.end(), comp).

🔗

template<container-compatible-range<T> R, class Alloc>
  constexpr priority_queue(from_range_t, R&& rg, const Alloc& a);

Effects: Initializes c with ranges::to<Container>(std::forward<R>(rg), a) and value-initializes comp; calls make_heap(c.begin(), c.end(), comp).
