A class that can be instantiated for the break control abstraction. Example usage:

  val mybreaks = new Breaks
  import mybreaks.{break, breakable}

  breakable {
    for (...) {
      if (...) break
    }
  }

Calls to break from one instantiation of Breaks will never target breakable objects of some other instantion.

A marker trait indicating that the Throwable it is mixed into is intended for flow control.

A trait for exceptions which, for efficiency reasons, do not fill in the stack trace.

An object that can be used for the break control abstraction. Example usage:

  import Breaks.{break, breakable}

Classes representing the components of exception handling. Each class is independently composable. Some common uses:

  import scala.util.control.Exception._
  import java.net._

  val s = "http://www.scala-lang.org/"
  val x1 = catching(classOf[MalformedURLException]) opt new URL(s)
  val x2 = catching(classOf[MalformedURLException], classOf[NullPointerException]) either new URL(s)
