Invoke the specified manipulator on the address of the value stored in the specified "nullable" object and on a prvalue of the category tag type for the dynamic category of the value. See {`bdlat_typecategory`|Category Tags and Enumerators} for documentation about category tags. Return the value from the invocation of manipulator. The manipulator must be a manipulator functor. See {`bdlat_typecategory`|`MANIPULATOR` Functors} for the requirements on manipulator. The behavior is undefined if object contains a null value.
