public interface Synchronizable
Implementations of this interface expose a lock object
via getLock()
so that callers can synchronize
externally on that lock:
if (iterator instanceof Synchronizable) { Object element = null; synchronized (((Synchronizable)iterator).getLock()) { if (iterator.hasNext()) element = iterator.next(); } }
In the example above, the calls to hasNext()
and
next()
are performed "atomically".
