[Solved] What does this mean in Scala? [closed]

by


A few pieces of information that might help when looking at code like this:

  • Calling an object or class as a function calls the appropriate apply method if there is one
  • Parentheses are often optional

so another way to rewrite the code above would be:

val route = HttpService.apply({
  case GET -> Root / "hello" =>
    Ok("Hello world.")
})

As noted in Diego’s answer, the function passed to apply in this case goes from some sort of HTTP request to some sort of HTTP response.
