Defined in header <queue>
template<class T, class Container, class Compare, class Alloc > struct uses_allocator<std::priority_queue<T, Compare, Container>, Alloc>     :std::uses_allocator<Container, Alloc>::type{};		(since C++11)

Provides a transparent specialization of the std::uses_allocator type trait for std::priority_queue: the container adaptor uses allocator if and only if the underlying container does.

Inherited from std::integral_constant

Member constants

value [static]

true (public static member constant)

Member functions

operator bool	converts the object to bool, returns value (public member function)
operator() (C++14)	returns value (public member function)

Member types

Type	Definition
value_type	bool
type	std::integral_constant<bool, value>

Example

Run this code

#include <memory>#include <queue>   static_assert(std::uses_allocator<std::priority_queue<int>, void>::value==false&&std::uses_allocator<std::priority_queue<int>, std::allocator<int>>::value==true);   int main(){}
