||
| template< class T, class... Args > static void construct( Alloc& a, T* p, Args&&... args ); |
(since C++11) | |
If possible, constructs an object of type T in allocated uninitialized storage pointed to by p, by calling
a.construct(p, std::forward<Args>(args)...)
If the above is not possible (e.g. a does not have the member function construct(),), then calls placement-new as
::new (static_cast<void*>(p)) T(std::forward<Args>(args)...)
