FiliResponseWriterSelector

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ResponseWriterSelector

Typically, a Fili program's response writing infrastructure will consist of a collection of unrelated ResponseWriters each responsible for serializing the ResultSet into a specific format, and a single ResponseWriter that chooses the correct one based on the current state of the DataApiRequest. This interface allows customers provide a clean interface to the logic that makes that selection. Its sole purpose is to take a `DataApiRequest` and return the `ResponseWriter` that should be used to write the response.
