執行緒
public void run() { // normally in a new Thread
try {
while (!Thread.interrupted()) {
selector.select();
Set selected = selector.selectedKeys();
Iterator it = selected.iterator();
while (it.hasNext())
dispatch((SelectionKey)(it.next());
selected.clear();
}
} catch (IOException ex) { /* ... */ }
}
void dispatch(SelectionKey k) {
Runnable r = (Runnable)(k.attachment());
if (r != null)
r.run();
}
