com.machinezoo.noexception.optional (NoException 1.9.1 API)

Variations of standard functional interfaces that return Optional instead of the raw value. They are usually obtained by calling a method on ExceptionHandler. They can be converted to standard functional interface by calling orElse and orElseGet methods. See NoException tutorial.
