import java.util.*;
import java.util.function.*;
import reactor.core.publisher.Flux;

public class %s implements CompilationResultFactory<%s> {
    public %s<%s> getResult() {
        %s
    }
};

The rules can be specified in yml property file or any other mechanism. It might contain the in/out parameters as well as the body of validation.
