跟王家林学习从1000个代码案例中学习人工智能和大数据实战第015讲：Scala中Tuple源码剖析及代码实践
package scala
/** A tuple of 22 elements; the canonical representation of a [[scala.Product22]].
*
* @constructor Create a new tuple with 22 elements. Note that it is more idiomatic to create a Tuple22 via `(t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t11, t12, t13, t14, t15, t16, t17, t18, t19, t20, t21, t22)`
* @param _1 Element 1 of this Tuple22
* @param _2 Element 2 of this Tuple22
* @param _3 Element 3 of this Tuple22
* @param _4 Element 4 of this Tuple22
* @param _5 Element 5 of this Tuple22
* @param _6 Element 6 of this Tuple22
* @param _7 Element 7 of this Tuple22
