Examples of com.google.common.base.Optional$Absent

A common alternative to using this class is to find or create a suitable null object for the type in question.

This class is not intended as a direct analogue of any existing "option" or "maybe" construct from other programming environments, though it may bear some similarities. @param < T> the type of instance that can be contained. {@code Optional} is naturallycovariant on this type, so it is safe to cast an {@code Optional} to {@code Optional} for any supertype {@code S} of {@code T}. @author Kurt Alfred Kluever @author Kevin Bourrillion @since Guava release 10
