Remarks

An asynchronous channel for stream-oriented listening sockets.

An asynchronous server-socket channel is created by invoking the #open open method of this class. A newly-created asynchronous server-socket channel is open but not yet bound. It can be bound to a local address and configured to listen for connections by invoking the #bind(SocketAddress,int) bind method. Once bound, the #accept(Object,CompletionHandler) accept method is used to initiate the accepting of connections to the channel's socket. An attempt to invoke the accept method on an unbound channel will cause a NotYetBoundException to be thrown.

Channels of this type are safe for use by multiple concurrent threads though at most one accept operation can be outstanding at any time. If a thread initiates an accept operation before a previous accept operation has completed then an AcceptPendingException will be thrown.

Socket options are configured using the #setOption(SocketOption,Object) setOption method. Channels of this type support the following options: <blockquote> <table class="striped"> <caption style="display:none">Socket options</caption> <thead> <tr> <th scope="col">Option Name</th> <th scope="col">Description</th> </tr> </thead> <tbody> <tr> <th scope="row"> java.net.StandardSocketOptions#SO_RCVBUF SO_RCVBUF</th> <td> The size of the socket receive buffer </td> </tr> <tr> <th scope="row"> java.net.StandardSocketOptions#SO_REUSEADDR SO_REUSEADDR</th> <td> Re-use address </td> </tr> </tbody> </table> </blockquote> Additional (implementation specific) options may also be supported.

<b>Usage Example:</b>

final AsynchronousServerSocketChannel listener =
                 AsynchronousServerSocketChannel.open().bind(new InetSocketAddress(5000));

             listener.accept(null, new CompletionHandler<AsynchronousSocketChannel,Void>() {
                 public void completed(AsynchronousSocketChannel ch, Void att) {
                     // accept the next connection
                     listener.accept(null, this);

                     // handle this connection
                     handle(ch);
                 }
                 public void failed(Throwable exc, Void att) {
                     ...
                 }
             });
