Defining a Map from String to Function in Scala

Question

I am trying to define a Map literal with key: String, value: (Any)=>String. I tried the following, but get a syntax error:

def foo(x         


        

Answer 1

This is how I did it to fulfill a similar requirement.

object MapToMethods {
private def increment(x: Int): Int = x+1
private def decrement(x: Int): Int = x-1

val m: Map[String, Int => Int] =Map("increment" -> increment, "decrement" ->decrement)

println(m("increment")(2)) //prints 3
println(m("decrement")(3)) //prints 2
}
