Class Unset

java.lang.Object

io.nosqlbench.virtdata.library.basics.shared.from_long.to_unset.Unset

All Implemented Interfaces:

LongFunction<Object>

public class Unset
extends Object
implements LongFunction<Object>

Always yields the VALUE.unset value, which signals to any consumers that the value provided should be considered undefined for any operation. This is distinct from functions which return a null, which is considered an actual value to be acted upon. It is deemed an error for any downstream user of this library to do anything with VALUE.unset besides explicitly acting like it wasn't provided. That is the point of VALUE.unset. The purpose of having such a value in this library is to provide a value type to help bridge between functional flows and imperative run-times. Without such a value, it would be difficult to simulate value streams in which some of the time values are set and other times they are not.
