trait Function4[-T1, -T2, -T3, -T4, +R] extends AnyRef

A function of 4 parameters.

Abstract Value Members From scala.Function4

abstract def apply(v1: T1, v2: T2, v3: T3, v4: T4): R

Apply the body of this function to the arguments.

  • returns
    • the result of function application.

(defined at scala.Function4)

Concrete Value Members From scala.Function4

def curried: (T1) ⇒ (T2) ⇒ (T3) ⇒ (T4) ⇒ R

Creates a curried version of this function.

  • returns
    • a function f such that f(x1)(x2)(x3)(x4) == apply(x1, x2, x3, x4)
  • Annotations
    • @ unspecialized ()

(defined at scala.Function4)

def tupled: ((T1, T2, T3, T4)) ⇒ R

Creates a tupled version of this function: instead of 4 arguments, it accepts a single scala.Tuple4 argument.

  • returns
    • a function f such that f((x1, x2, x3, x4)) == f(Tuple4(x1, x2, x3, x4)) == apply(x1, x2, x3, x4)
  • Annotations
    • @ unspecialized () (defined at scala.Function4)
