This is a pretty straight forward question, but I have found a need to unregister a selector overlooking my socket channel for java.
SocketChannel client = myServer.accept(); //forks off another client socket
client.configureBlocking(false);//this channel takes in multiple request
client.register(mySelector, SelectionKey.OP_READ | SelectionKey.OP_WRITE);//changed from r to rw
Where I can later in the program call something like
client.deregister(mySelector);
And that the selector will no longer catch data keys for that socket channel. This would make life much easier for me given my server/client design.
Call cancel()
on the selection key:
SelectionKey key = client.register(mySelector,
SelectionKey.OP_READ | SelectionKey.OP_WRITE);
...
key.cancel();
or
...
SelectionKey key = client.keyFor(mySelector);
key.cancel();
