public enum Immutable
extends Enum<Immutable>
Indicate whether the immutable collection contains a COPY of the collection (neither changeable by the user of the immutable collection, nor by anyone holding a pointer to the original collection), or a WRAP for the original collection (not changeable by the user of the immutable collection, but can be changed by anyone holding a pointer to the original collection that is wrapped).
