/**
 * A tuple with 9 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>Warning: If you subclass Tuple9, then be sure to either
 *
 * <ul>
 *   <li>not add any new fields, or
 *   <li>make it a POJO, and always declare the element type of your DataStreams/DataSets to your
 *       descendant type. (That is, if you have a "class Foo extends Tuple9", then don't use
 *       instances of Foo in a DataStream&lt;Tuple9&gt; / DataSet&lt;Tuple9&gt;, but declare it as
 *       DataStream&lt;Foo&gt; / DataSet&lt;Foo&gt;.)
 * </ul>
 *
 * @see Tuple
 * @param <T0> The type of field 0
