Interface Index<T>

All Superinterfaces:

Iterable<T>, Serializable

All Known Implementing Classes:

ArrayIndex, DynamicEnum, DynamicEnum.Coproduct, DynamicEnum.Product, EnumIndex, HashIndex, SetIndex

public interface Index<T>
extends Iterable<T>, Serializable

An index is a totally ordered finite collection, the generalization of an enum type. An index maintains a one-to-one relationship between its elements and the integers 0 to n-1.
