@Public
public class Tuple22<T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14,T15,T16,T17,T18,T19,T20,T21>
extends Tuple

A tuple with 22 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 getField(int) method. The tuple field positions start at zero.

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.

Warning: If you subclass Tuple22, then be sure to either

• not add any new fields, or
• 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 Tuple22", then don't use instances of Foo in a DataStream<Tuple22> / DataSet<Tuple22>, but declare it as DataStream<Foo> / DataSet<Foo>.)

Creates a new tuple and assigns the given values to the tuple's fields. This is more convenient than using the constructor, because the compiler can infer the generic type arguments implicitly. For example: Tuple3.of(n, x, s) instead of new Tuple3<Integer, Double, String>(n, x, s)
