@FunctionalInterface
public interface AccessorInvoker<T,R>

Functional interface for accessing a value from a field.

The field must be part of the code created for this functional interface, as there is no way to pass the field in during invocation.

This interface is almost identical to Function save the exceptions thrown, which is the reason for its existence.
