|   pointer allocate( size_type n );  | 
(1) | (since C++11) | 
|   pointer allocate( size_type n, const_void_pointer hint );  | 
(2) | (since C++11) | 
1) Uses the outer allocator to allocate uninitialized storage, by calling std::allocator_traits<OuterAlloc>::allocate(outer_allocator(), n)
2) Uses the outer allocator to allocate uninitialized storage with the memory locality hint provided, by calling std::allocator_traits<OuterAlloc>::allocate(outer_allocator(), n, hint)
[edit] Parameters
| n | - | the number of objects to allocate storage for | 
| hint | - | pointer to a nearby memory location | 
[edit] Return value
The pointer to the allocated storage
