26  * When nio application uses Selector.selectedKeys(),
27  * ASSelector will return a ASSet instance, where it will wrap
28  * those selection keys used for OP_ACCEPT.
29  * Nio application might use Set.iterator() to remove the
30  * processed SelectionKey from the selectedSet. We provide
31  * a wrapper Iterator so that even the actual selectedSet in
32  * the Selector is modified.
