+ * A channel that supports asynchronous I/O operations. Asynchronous I/O

+ * <ol>
+ * <li><pre>{@link Future}&lt;V&gt; <em>operation</em>(<em>...</em>)</pre></li>
+ * <li><pre>Future&lt;V&gt; <em>operation</em>(<em>...</em> A attachment, {@link CompletionHandler}&lt;V,? super A&gt handler)</pre></li>
+ * </ol>
+ *
+ * where <i>operation</i> is the name of the I/O operation (read or write for
+ * example), <i>V</i> is the result type of the I/O operation, and <i>A</i> is
+ * the type of an object attached to the I/O operation to provide context when
+ * consuming the result. The attachment is important for cases where a
+ * <em>state-less</em> {@code CompletionHandler} is used to consume the result
+ * of many I/O operations.
+ *
+ * <p> In the first form, the methods defined by the {@link Future Future}
+ * interface may be used to check if the operation has completed, wait for its
+ * completion, and to retrieve the result. In the second form, a {@link
+ * CompletionHandler} is invoked to consume the result of the I/O operation when
+ * it completes, fails, or is cancelled.
+ *
+ * <p> A channel that implements this interface is <em>asynchronously
+ * closeable</em>: If an I/O operation is outstanding on the channel and the
+ * channel's {@link #close close} method is invoked, then the I/O operation
+ * fails with the exception {@link AsynchronousCloseException}.
+ *
+ * <p> Asynchronous channels are safe for use by multiple concurrent threads.
+ * Some channel implementations may support concurrent reading and writing, but
+ * may not allow more than one read and one write operation to be outstanding at
+ * any given time.
+ *
+ * <h4>Cancellation</h4>
+ *
+ * <p> The {@code Future} interface defines the {@link Future#cancel cancel}
+ * method to cancel execution of a task.
+ *
+ * <p> Where the {@code cancel} method is invoked with the {@code
+ * mayInterruptIfRunning} parameter set to {@code true} then the I/O operation
+ * may be interrupted by closing the channel. This will cause any other I/O
+ * operations outstanding on the channel to complete with the exception {@link
+ * AsynchronousCloseException}.
+ *
+ * <p> If a {@code CompletionHandler} is specified when initiating an I/O
+ * operation, and the {@code cancel} method is invoked to cancel the I/O
+ * operation before it completes, then the {@code CompletionHandler}'s {@link
+ * CompletionHandler#cancelled cancelled} method is invoked.
+ *
+ * <p> If an implementation of this interface supports a means to cancel I/O
+ * operations, and where cancellation may leave the channel, or the entity to
+ * which it is connected, in an inconsistent state, then the channel is put into
+ * an implementation specific <em>error state</em> that prevents further
+ * attempts to initiate I/O operations on the channel. For example, if a read
+ * operation is cancelled but the implementation cannot guarantee that bytes
+ * have not been read from the channel then it puts the channel into error state
+ * state; further attempts to initiate a {@code read} operation causes an
+ * unspecified runtime exception to be thrown.
+ *
+ * <p> Where the {@code cancel} method is invoked to cancel read or write
+ * operations then it recommended that all buffers used in the I/O operations be
+ * discarded or care taken to ensure that the buffers are not accessed while the
+ * channel remains open.

+ *
+ * <p> An asynchronous channel group encapsulates the mechanics required to

+ * asynchronous channels} that are bound to the group. A group has an associated
+ * thread pool to which tasks are submitted to handle I/O events and dispatch to

+ * asynchronous operations performed on channels in the group. In addition to
+ * handling I/O events, the pooled threads may also execute other tasks required
+ * to support the execution of asynchronous I/O operations.
+ *
+ * <p> An asynchronous channel group is created by invoking the {@link
+ * #withFixedThreadPool withFixedThreadPool} or {@link #withCachedThreadPool
+ * withCachedThreadPool} methods defined here. Channels are bound to a group by
+ * specifying the group when constructing the channel. The associated thread
+ * pool is <em>owned</em> by the group; termination of the group results in the
+ * shutdown of the associated thread pool.
+ *
+ * <p> In addition to groups created explicitly, the Java virtual machine
+ * maintains a system-wide <em>default group</em> that is constructed
+ * automatically. Asynchronous channels that do not specify a group at
+ * construction time are bound to the default group. The default group has an
+ * associated thread pool that creates new threads as needed. The default group
+ * may be configured by means of system properties defined in the table below.
+ * Where the {@link java.util.concurrent.ThreadFactory ThreadFactory} for the
+ * default group is not configured then the pooled threads of the default group

+ * expected <em>identity</em>.
+ *
+ * <p> Where an I/O operation completes immediately, and the initiating thread
+ * is one of the pooled threads in the group then the completion handler may
+ * be invoked directly by the initiating thread. To avoid stack overflow, an
+ * implementation may impose a limit as to the number of activations on the

+ *
+ * <p> The {@link #shutdown() shutdown} method is used to initiate an <em>orderly

+ * further attempts to construct a channel that binds to the group will throw
+ * {@link ShutdownChannelGroupException}. Whether or not a group is shutdown can
+ * be tested using the {@link #isShutdown() isShutdown} method. Once shutdown,
+ * the group <em>terminates</em> when all asynchronous channels that are bound to
+ * the group are closed, all actively executing completion handlers have run to
+ * completion, and resources used by the group are released. No attempt is made
+ * to stop or interrupt threads that are executing completion handlers. The
+ * {@link #isTerminated() isTerminated} method is used to test if the group has
+ * terminated, and the {@link #awaitTermination awaitTermination} method can be
+ * used to block until the group has terminated.
+ *
+ * <p> The {@link #shutdownNow() shutdownNow} method can be used to initiate a
+ * <em>forceful shutdown</em> of the group. In addition to the actions performed
+ * by an orderly shutdown, the {@code shutdownNow} method closes all open channels
+ * in the group as if by invoking the {@link AsynchronousChannel#close close}

+/**
+ * An asynchronous channel for stream-oriented listening sockets.
+ *
+ * <p> An asynchronous server-socket channel is created by invoking the
+ * {@link #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 {@link #bind(SocketAddress,int) bind} method. Once bound,
+ * the {@link #accept(Object,CompletionHandler) accept} method
+ * is used to initiate the accepting of connections to the channel's socket.
+ * An attempt to invoke the <tt>accept</tt> method on an unbound channel will
+ * cause a {@link NotYetBoundException} to be thrown.
+ *
+ * <p> 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 {@link AcceptPendingException} will be thrown.
+ *
+ * <p> Socket options are configured using the {@link #setOption(SocketOption,Object)
+ * setOption} method. Channels of this type support the following options:
+ * <blockquote>
+ * <table border>
+ *   <tr>
+ *     <th>Option Name</th>
+ *     <th>Description</th>
+ *   </tr>
+ *   <tr>
+ *     <td> {@link java.net.StandardSocketOption#SO_RCVBUF SO_RCVBUF} </td>
+ *     <td> The size of the socket receive buffer </td>
+ *   </tr>
+ *   <tr>
+ *     <td> {@link java.net.StandardSocketOption#SO_REUSEADDR SO_REUSEADDR} </td>
+ *     <td> Re-use address </td>
+ *   </tr>
+ * </table>
+ * </blockquote>
+ * Additional (implementation specific) options may also be supported.
+ *
+ * <p> <b>Usage Example:</b>
+ * <pre>
+ *  final AsynchronousServerSocketChannel listener =
+ *      AsynchronousServerSocketChannel.open().bind(new InetSocketAddress(5000));
