get

If T has a nested type allocator_type, returns t.get_allocator(). Otherwise returns a.

A program may specialise this traits type if the T template parameter in the specialisation is a user-defined type. The template parameter Allocator shall be a type meeting the Allocator requirements.

Specialisations shall meet the following requirements, where t is a const reference to an object of type T, and a is an object of type Allocator.
