Method Details

handleConnection

void handleConnection(Socket socket)
               throws IOException

Handle the connection.

Parameters:

socket - connection socket

Throws:

IOException - if needed

stop

void stop(Thread thread,
 Socket socket)

Receive notification that the server is shutting down. This method should ensure that the thread currently executing handleConnection() returns as soon as possible.

After this method returns, the socket will be closed (if not already). So one way to implement this method is to simply do nothing, which will trigger an IOException on the next access from within handleConnection().

Alternately, set some flag that handleConnection() detects each time around its processing loop, or use Thread.interrupt(), etc.

In any case, it is important that handleConnection() thread does eventually return, otherwise the thread invoking SocketAcceptor.stop() will hang.

Note: it may be that handleConnection() has already returned when this method is invoked, in which case this method should do nothing.

Parameters:

thread - the thread invoking handleConnection()

socket - connection socket
