Interface Summary

Interface	Description
Assignment<V>	An assignment may or may not be assigned, the assigned value can be retrieved with Supplier.get() and will return null if unassigned, and may be assigned with Assignment.set(Object) if the assignment allows (re-)assignment.
AtMostOne<T>	This class offers a subtle functionality which is not available in the Collection API of Java: to retrieve the only element that is expected to be present, and, importantly, throw an exception if there are elements that will be discarded if assuming that there is at most one element present.

SetsNamedValue<V>
ViewableAsOptional<V>
ViewableAsOptional.Single<V>	A Supplier which is also ViewableAsOptional.
