Tuple4

final case class Tuple4[+T1, +T2, +T3, +T4](_1: T1, _2: T2, _3: T3, _4: T4) extends Product4[T1, T2, T3, T4]

A tuple of 4 elements; the canonical representation of a scala.Product4.

A tuple of 4 elements; the canonical representation of a scala.Product4.

Value Params
_1

Element 1 of this Tuple4

_2

Element 2 of this Tuple4

_3

Element 3 of this Tuple4

_4

Element 4 of this Tuple4

Constructor

Create a new tuple with 4 elements. Note that it is more idiomatic to create a Tuple4 via (t1, t2, t3, t4)

inline def ++[This >: (T1, T2, T3, T4) <: Tuple](that: Tuple): Concat[This, that]

Return a new tuple by concatenating this tuple with that tuple.

inline def apply[This >: (T1, T2, T3, T4) <: NonEmptyTuple](n: Int): Elem[This, n]

Get the i-th element of this tuple.

inline def drop[This >: (T1, T2, T3, T4) <: Tuple](n: Int): Drop[This, n]

inline def map[F[_]](f: [t] => (x$1: t) => F[t]): Map[(T1, T2, T3, T4), F]

Called on a tuple (a1, ..., an), returns a new tuple (f(a1), ..., f(an)).

Called on a tuple (a1, ..., an), returns a new tuple (f(a1), ..., f(an)). The result is typed as (F[A1], ..., F[An]) if the tuple type is fully known. If the tuple is of the form a1 *: ... *: Tuple (that is, the tail is not known to be the cons type.

override def productElement(n: Int): Any

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

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

Value Params

Given two tuples, (a1, ..., an) and (a1, ..., an), returns a tuple ((a1, b1), ..., (an, bn)).

Given two tuples, (a1, ..., an) and (a1, ..., an), returns a tuple ((a1, b1), ..., (an, bn)). If the two tuples have different sizes, the extra elements of the larger tuple will be disregarded. The result is typed as ((A1, B1), ..., (An, Bn)) if at least one of the tuple types has a EmptyTuple tail. Otherwise the result type is (A1, B1) *: ... *: (Ai, Bi) *: Tuple
