using value_type = typename allocator_traits< _Alloc >::value_type

Public Member Functions

__allocated_ptr (_Alloc &__a, pointer __ptr) noexcept
Take ownership of __ptr.
template<typename _Ptr , typename _Req = _Require<is_same<_Ptr, value_type*>>> __allocated_ptr (_Alloc &__a, _Ptr __ptr)
Convert __ptr to allocator's pointer type and take ownership of it.
__allocated_ptr (__allocated_ptr &&__gd) noexcept
Transfer ownership of the owned pointer.
~__allocated_ptr ()
Deallocate the owned pointer.
value_type * get ()
Get the address that the owned pointer refers to.
__allocated_ptr & operator= (std::nullptr_t) noexcept
