Returns a.allocate(n, hint)
if that expression is well-formed, otherwise returns a.allocate(n)

static auto std::allocator_traits< _Alloc >::construct | ( | _Alloc & | __a, |
_Tp * | __p, | ||

Construct an object of type _Tp.
__a | An allocator. |
__p | Pointer to memory of suitable size and alignment for Tp |
__args | Constructor arguments. |
Calls __a.construct(__p, std::forward<Args>(__args)...)
if that expression is well-formed, otherwise uses placement-new to construct an object of type _Tp at location __p from the arguments __args...
static void std::allocator_traits< _Alloc >::deallocate | ( | _Alloc & | __a, |
pointer | __p, | ||
size_type | __n | ||
) | [inline, static, inherited] |
Deallocate memory.
__a | An allocator. |
__p | Pointer to the memory to deallocate. |
__n | The number of objects space was allocated for. |
Calls a.deallocate(p, n)
Definition at line 332 of file bits/alloc_traits.h.
static void std::allocator_traits< _Alloc >::destroy | ( | _Alloc & | __a, |
_Tp * | __p | ||
) | [static, inherited] |
Destroy an object of type _Tp.
__a | An allocator. |
__p | Pointer to the object to destroy |
Calls __a.destroy(__p)
if that expression is well-formed, otherwise calls __p->~_Tp()
