trait Monitor extends AnyRef

A Monitor is a composable exception handler. It is independent of position, divorced from the notion of a call stack. Monitors do not recover values from failed computations: It handles only true exceptions that may require cleanup.

  4. def andThen(next: Monitor): Monitor

    A new monitor which first handles the exception with this, then passes it onto next unconditionally.

    A new monitor which first handles the exception with this, then passes it onto next unconditionally. The new monitor handles the exception if either this or next does.

  5. def apply(f: ⇒ Unit): Unit

    Run f inside of the monitor context.

    Run f inside of the monitor context. If f throws an exception - directly or not - it is handled by this monitor.
