I wrote a function which returns a function based on the String argument it receives. The code looks as follow:

def getFunction(str:String) : Map[String, String] => String={
    val s = str.charAt(0).toString()
    s matches {
      case "x" => (arg:Map[String, String]) => arg("random")
      case _ =>(arg:Map[String, String]) => arg("")
    }
  }

This is giving a compilation exception 

Description Resource    Path    Location    Type
missing parameter type for expanded function The argument types of an anonymous function must be fully known. (SLS 8.5) Expected type was: String   line 9 Scala Problem.

I looked into: The argument types of an anonymous function must be fully known. (SLS 8.5).

But could understand the solution. Can anyone explain what is wrong with above code.

Thanks

    The only thing that seems incorrect about your function is that you use `matches` (regex pattern matching, returns boolean) function instead of `match` keyword (structural pattern matching). – Dmitry Kuskov Sep 06 '16 at 09:57
