    @dragas commented on @Paul Woitaschek’s file https://kotlinlang.slack.com/files/U0KBF8D7V/F5S727T1S/rootcause_kt.kt: I agree with @nhaarman. You should look into https://en.wikipedia.org/wiki/Cycle_detection

    is there something like jboss’ type safe logging framework for kotlin? https://docs.jboss.org/seam/3/latest/reference/en-US/html/solder-logging.html

    how can there be a circular reference? i mean sure you can build one, but what code would produce that without itself producing a stack overflow?

    Code that has detection for circular invokation and cancels itself

    and then throws 😛

    or rather it throws in every iteration

    i think it can not happen and thats why guava does not check for it

    @christophsturm Take a look at 
    public Throwable::initCause
    .
  • c

    and then?

    that method makes sure that an exception cannot have itself as cause. which makes sense.

    It's not stopping you from having circular reference.
    Copy code
    val ex1 = Exception("ex1")
        val ex2 = Exception("ex2", ex1)
        ex1.initCause(ex2)

    sure it is, it checks for exactly that

    06/12/2017, 11:40 AM
    ah ex1 right
  • c

    06/12/2017, 11:41 AM
    thats what i was refering to when i said “sure you can build one”

    except .reversed

    06/12/2017, 11:41 AM
    but still it can not really happen in code that actually throws its exceptions

    how could I convert the following code to Kotlin? while((bytesRead = in.read(buffer)) > 0 ) { out.write(buffer, 0, bytesRead); }

    Assuming 
    in
    is an 
    InputStream
    and 
    out
    is an `OutputStream`: 
    in.copyTo(out)
    .

    'in' is Key Word in kotlin so I rename it to input

    is this same code of java just one line ?
  • d

    diesieben07

    06/12/2017, 12:32 PM
    Well, it copies everything from 
    in
    to 
    out
    .

    06/12/2017, 12:32 PM
    oh so no need for while read(buffer)) > 0
