In my current method, I am trying to make a series of calls and if any of them fail, I want to be able to continue running the remainder (while capturing the Exception that was thrown). I am having a hard time figuring this out in Scala.
So in this example, I want to kick off each of these calls - RunA, RunB and RunC but if RunB throws an exception, I want to print that and continue kicking off RunC after that.
var result = Try {
new RunA()
new RunB()
new RunC()
} catch {
case e: Throwable => e.printStackTrace()
false
}
Outside of having them all individually wrapped in a Try/Catch, I am sure there are better ways to do this which is why I am hoping someone can help with this.
I looked at the 'Ignoring' exception but it appears to completely ignore the exception which I want to atleast log.
Thanks!
First, don't mix try { ... } catch { ... } up with scala.util.Try{ ... }.
You can
import scala.util._
val runA = Try{ new RunA }
val runB = Try{ new RunB }
val runC = Try{ new RunC }
and then deal with the exceptions as you see fit. For instance, if you want to print and continue, you could deal with the try statements right there:
def getOrPrint[A](f: => A): Option[A] = Try{ f } match {
case Success(x) => Some(x)
case Failure(e) => e.printStackTrace; None
}
getOrPrint{ new RunA }
...
