But it's not the cleanest way by any measure. It has tighter internal coupling than any other easy to imagine way.
Most of the times, people will use the list normal interface to take the data.
If performance is a requirement, most OOP people will create a database interface, that the linked list class can write without taking outside of its interface. Most FP people would do it the other way around, and create an interface to applying data to a function that the list can implement. Either way, it can tie with the dirty introspection in performance.
