- * A tuple with 17 fields. Tuples are strongly typed; each field may be of a separate type.
- * The fields of the tuple can be accessed directly as public fields (f0, f1, ...) or via their position
- * through the {@link #getField(int)} method. The tuple field positions start at zero.
- * <p>
- * Tuples are mutable types, meaning that their fields can be re-assigned. This allows functions that work
- * with Tuples to reuse objects in order to reduce pressure on the garbage collector.

- * <p>
- * Tuples are mutable types, meaning that their fields can be re-assigned. This allows functions that work
