Kann eine von SelectedKeys ungültig ist? ⇐ Java

[Guest]

Ich habe den folgenden Code.

Code: Select all

            final SelectionKey clientKey;
if (client.connect(_Rfc863Constants.SERVER_ENDPOINT)) {
log.debug("connected to {}", client.getRemoteAddress());
clientKey = client.register(selector, SelectionKey.OP_WRITE);
} else {
clientKey = client.register(selector, SelectionKey.OP_CONNECT);
}
_Rfc863Utils.readQuitAndCall(() -> {
clientKey.cancel(); //
