Interface Tuple<X>

All Superinterfaces:

Iterable<X>

All Known Implementing Classes:

Tuple0, Tuple1, Tuple2, Tuple3, Tuple4, Tuple5, Tuple6, Tuple7, Tuple8, TupleN

public interface Tuple<X>
extends Iterable<X>

A Tuple is a sequence of items of the same class of item. Tuples are immutable. .equals is "by value".
