Hi: I've written a x-10 problem as follows:
public class Fun2 { public static def main(argv:Rail[String]!) = { val a : DistArray[Int] = DistArray.make[Int](Dist.makeBlock(1..35),((i):Point)=>i*i); x10.io.Console.OUT.println(str(a)); } static def str[T](a:DistArray[T]):String { var s : String = ""; var first : Boolean = true; for(point in a) { if (first) first = false; else s += ","; s += a(point).toString(); } return s; } } It can be compiled. And when running, the program crashed. The output info is as follows: x10.lang.BadPlaceException: point (10) not defined at (Place 0) at x10.array.DistArray$2.apply(DistArray.java:613) at x10.array.DistArray$2.apply(DistArray.java:1) at x10.array.BaseRegion.check(BaseRegion.java:120) at x10.array.DistArray.checkPlace(DistArray.java:1407) at x10.array.DistArray.apply(DistArray.java:998) at Fun2.str(Fun2.java:149) at Fun2.main(Fun2.java:106) at Fun2$Main$2.apply(Fun2.java:51) at x10.lang.Runtime$5.apply(Runtime.java:4454) at x10.lang.Activity.run(Activity.java:217) at x10.lang.Runtime$Worker$3.apply(Runtime.java:3455) at x10.runtime.impl.java.Runtime.runAt(Runtime.java:105) at x10.lang.Runtime$Worker.loop(Runtime.java:3422) at x10.lang.Runtime$Worker.apply(Runtime.java:3308) at x10.lang.Runtime$Pool.apply(Runtime.java:3842) at x10.lang.Runtime.start(Runtime.java:4461) at Fun2$Main.main(Fun2.java:34) at x10.runtime.impl.java.Runtime.run(Runtime.java:50) at java.lang.Thread.run(Unknown Source) When changing the sentence: s += a(point).toString(); into the new form: s += at(a.dist(point)){a(point).toString()}; it runs well. In my opinion, toString is global. And therefore I don't need to use the "at" clause. Are there any problems here?
