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

Provides a transparent specialization of the std::uses_allocator type trait for std::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::queue<int>, void>::value == false &&
    std::uses_allocator<std::queue<int>, std::allocator<int>>::value == true
);
 
int main() {}
