How do you define a type for a function in Scala? -

I hope there is a way to define a type for a function in Scala.

For example, say, I have a function that takes two entries and gives a boolean, I can define a function that it uses:

  def checkInts (f: (int, int) => boolean) = {// do stuff}

Is there any way to define the type of F? Then I can do something like:

  def checkin (f: MyFunctionType)

  def check in (F: option [MyFunctionType])

  attribute foo {type MyFunction = (Int, int) = & gt; Boolean Df Check In (F: MyFunction) Def Check In (F: Option [MyFunction])}
