/**
* A channel that supports asynchronous I/O operations. Asynchronous I/O
* operations will usually take one of two forms:
*
* <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.

* 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.
