      const allocator<Other>& _Right
   );

  An allocator object to be assigned to another such object.

반환 값

A reference to the allocator object

설명

The template assignment operator does nothing. In general, however, an allocator object assigned to another allocator object should compare equal to it and permit intermixing of object allocation and freeing between the two allocator objects.
