Examples of org.apache.mina.core.service.IoAcceptor

org.apache.mina.core.service.IoAcceptor
Accepts incoming connection, communicates with clients, and fires events to {@link IoHandler}s.
Please refer to EchoServer example.
You should bind to the desired socket address to accept incoming connections, and then events for incoming connections will be sent to the specified default {@link IoHandler}.
Threads accept incoming connections start automatically when {@link #bind()} is invoked, and stop when {@link #unbind()} is invoked. @author The Apache MINA Project (dev@mina.apache.org) @version $Rev: 751415 $, $Date: 2009-03-08 14:17:11 +0100 (Sun, 08 Mar 2009) $
