Function2
scala.Function2
A function of 2 parameters.
In the following example, the definition of max is shorthand, conceptually, for the anonymous class definition anonfun2, although the implementation details of how the function value is constructed may differ:
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))
}
