Read All Lines of BufferedReader in Scala into a String

问题

How can I read all of a BufferedReader's lines and store into a String?

 val br = new BufferedReader(...)
 val str: String = getAllLines(br) // getAllLines() -- is where I need help

This is how I deal with a BufferedReader in Scala:

val br:BufferedReader = ???
val strs = Stream.continually(br.readLine()).takeWhile(_ != null)

You will have a string for each line from the reader. If you want it in one single string:

val str = Stream.continually(br.readLine()).takeWhile(_ != null).mkString("\n")
