static pointer allocate(Alloc& a, size_type n);
1
#
Returns: a.allocate(n).
static pointer allocate(Alloc& a, size_type n, const_void_pointer hint);
2
#
Returns: a.allocate(n, hint) if that expression is well-formed; otherwise, a.allocate(n).
static void deallocate(Alloc& a, pointer p, size_type n);
3
#
Effects: Calls a.deallocate(p, n).
4
#
Throws: Nothing.
template <class T, class... Args> static void construct(Alloc& a, T* p, Args&&... args);
5
#
Effects: Calls a.construct(p, std​::​forward<Args>(args)...) if that call is well-formed; otherwise, invokes ​::​new (static_­cast<void*>(p)) T(std​::​forward<Args>(args)...).
template <class T> static void destroy(Alloc& a, T* p);
6
#
Effects: Calls a.destroy(p) if that call is well-formed; otherwise, invokes p->~T().
static size_type max_size(const Alloc& a) noexcept;
7
#
Returns: a.max_­size() if that expression is well-formed; otherwise, numeric_­limits<size_­type>​::​​max()/sizeof(value_­type).
static Alloc select_on_container_copy_construction(const Alloc& rhs);
8
#
Returns: rhs.select_­on_­container_­copy_­construction() if that expression is well-formed; otherwise, rhs.
