std::uses_allocator<std::stack>
Defined in header <stack> | ||
|---|---|---|
template< class T, class Container, class Alloc >
struct uses_allocator<std::stack<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::stack: 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) |

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