Java Question

Is there a way to de-register a selector on a socket channel

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


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.

Answer Source

Call cancel() on the selection key:

SelectionKey key = client.register(mySelector,
    SelectionKey.OP_READ | SelectionKey.OP_WRITE);


SelectionKey key = client.keyFor(mySelector);
