What's the Scala way to implement a retry-able call like this one?

Question

Still the newbie in Scala and I\'m now looking for a way to implement the following code on it:

@Override
public void store(InputStream source, String destin         


        

Answer 1

A reusable object/method with a pause between attempts:

Retry(3, 2 seconds) { /* some code */ }

Code:

object Retry {
  def apply[A](times: Int, pause: Duration)(code: ⇒ A): A = {
    var result: Option[A] = None
    var remaining = times
    while (remaining > 0) {
      remaining -= 1
      try {
        result = Some(code)
        remaining = 0
      } catch {
        case _ if remaining > 0 ⇒ Thread.sleep(pause.toMillis)
      }
    }
    result.get
  }
}
