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 static interface FDBDatabase.ExceptionMapper

Function for mapping an underlying exception to a synchronous failure. It is possible for this function to be called with the result of calling it previously. Therefore, if wrapping exceptions with some application-specific exception class, it is best to check for being passed an ex that is already of that class and in that case just return it.
