Jungtaek Lim commented on STORM-1582:
-------------------------------------
Seems like we're porting clojure codes to java codes with keeping styles.
Actually I didn't see any codes like asyncLoop in other projects written in
Java.
Eventually whole codebase will be refactored to Java style.
> asyncLoop will calls repeatedly when the return type of call only is Long

> It can repeatedly invoke fn.call when only the return type of call is Long. I
> think it maybe a bug.
> public static SmartThread asyncLoop(final Callable afn,
> boolean isDaemon, final Thread.UncaughtExceptionHandler eh,
> int priority, final boolean isFactory, boolean startImmediately,
> String threadName) {
> SmartThread thread = new SmartThread(new Runnable() {
> public void run() {
> Object s;
> try {
> Callable fn = isFactory ? (Callable) afn.call() : afn;
> while ((s = fn.call()) instanceof Long) { //////????????
> Time.sleepSecs((Long) s);
> }
