Why scala's pattern maching does not work in for loops for type matching?

Question

I\'m coding against an API that gives me access to remote file system. The API returns a list of files and directories as list of node objects (parent to file and directory)

Answer 1

How about this:

val listOfBaseObjects: List[Any] = List[Any]("a string", 1:Integer);

for (x <- listOfBaseObjects if x.isInstanceOf[String]) {
  println(x)
}
