Scala: thread-safe circular iterator -


what correct way create thread-safe, infinite circular iterator in scala? seems following not thread safe (iterating simulataneously multiple threads on iterator throws exceptions):

how correct make thread-safe?

i've ran same question think can safe implementation dependent discussed here.

iterator.synchronized(   iterator.next() )
