scala.Tuple2

case class Tuple2[+T1, +T2](_1: T1, _2: T2) extends Product2[T1, T2] with Product with Serializable

A tuple of 2 elements; the canonical representation of a scala.Product2.

Value Members From scala.Product2

def productElement(n: Int): Any

Returns the n-th projection of this product if 0 < n <= productArity, otherwise throws an IndexOutOfBoundsException .

  • n
    • number of the projection to be returned
  • returns
    • same as ._(n+1) , for example productElement(0) is the same as ._1 .
  • Definition Classes
    • Product2 → Product
  • Annotations
    • @ throws (clazz = classOf[IndexOutOfBoundsException])
  • Exceptions thrown *

Instance Constructors From scala.Tuple2

new Tuple2(_1: T1, _2: T2)

Create a new tuple with 2 elements. Note that it is more idiomatic to create a Tuple2 via (t1, t2)

  • _1
    • Element 1 of this Tuple2
  • _2
    • Element 2 of this Tuple2
