Trait Function2.Function2

trait Function2[-T1, -T2, +R] extends AnyRef

A function of 2 parameters.

In the following example, the definition of max is a shorthand for the anonymous class definition anonfun2:

object Main extends App {
  val max = (x: Int, y: Int) => if (x < y) y else x

  val anonfun2 = new Function2[Int, Int, Int] {
    def apply(x: Int, y: Int): Int = if (x < y) y else x
  }
  assert(max(0, 1) == anonfun2(0, 1))
}

Abstract methods

Source

def apply(v1: T1, v2: T2): R

Apply the body of this function to the arguments.

Concrete methods

Source

def curried: T1 => T2 => R

Creates a curried version of this function.

Source

override def toString(): String

Returns a string representation of the object.

The default representation is platform dependent.

Source

def tupled: ((T1, T2)) => R

Creates a tupled version of this function: instead of 2 arguments, it accepts a single scala.Tuple2 argument.
