static void destroy ( Alloc & a, T * p ) ; |
(since C++11)
(constexpr since C++20) |
|
Calls the destructor of the object pointed to by
p
. If possible, does so by calling
a.
destroy
(
p
)
. If not possible (e.g.
Alloc
does not have the member function
destroy()
), then calls
the destructor of
*
p
directly, as
p

~T

)
(until C++20)
std::
destroy_at
(
p
)
(since C++20)
.
Parameters
a | - | allocator to use for destruction |
p | - | pointer to the object being destroyed |
Return value
(none)
Notes
Because this function provides the automatic fall back to direct call to the destructor, the member function
destroy()
is an optional
Allocator
requirement since C++11.
