-/**
- * Continuation.
- * 
- * A continuation is a mechanism by which a HTTP Request can be suspended and
- * restarted after a timeout or an asynchronous event has occurred.
- * <p>
- * The continuation mechanism is a portable mechanism that will work 
- * asynchronously without additional configuration of all jetty-7, 
- * jetty-8 and Servlet 3.0 containers.   With the addition of 
- * the {@link ContinuationFilter}, the mechanism will also work
- * asynchronously on jetty-6 and non-asynchronously on any 
- * servlet 2.5 container.
- * <p>
- * The Continuation API is a simplification of the richer async API
- * provided by the servlet-3.0 and an enhancement of the continuation
- * API that was introduced with jetty-6. 
- * </p>
- * <h1>Continuation Usage</h1>
- * <p>
- * A continuation object is obtained for a request by calling the 
- * factory method {@link ContinuationSupport#getContinuation(ServletRequest)}.
- * The continuation type returned will depend on the servlet container
- * being used.
- * </p> 
- * <p>
- * There are two distinct style of operation of the continuation API.
- * </p>
- * <h3>Suspend/Resume Usage</h3> 
- * <p>The suspend/resume style is used when a servlet and/or
- * filter is used to generate the response after a asynchronous wait that is
- * terminated by an asynchronous handler.
- * </p>
- * <pre>
- * <b>Filter/Servlet:</b>
- *   // if we need to get asynchronous results
- *   Object results = request.getAttribute("results);
- *   if (results==null)
- *   {
- *     Continuation continuation = ContinuationSupport.getContinuation(request);
- *     continuation.suspend();
- *     myAsyncHandler.register(continuation);
- *     return; // or continuation.undispatch();
- *   }
- * 
- * async wait ...
- * 
- * <b>Async Handler:</b>
- *   // when the waited for event happens
- *   continuation.setAttribute("results",event);
- *   continuation.resume();
- *   
- * <b>Filter/Servlet:</b>
- *   // when the request is redispatched 
- *   if (results==null)
- *   {
- *     ... // see above
- *   }
- *   else
- *   {
- *     response.getOutputStream().write(process(results));
- *   }
- * </pre> 
- * <h3>Suspend/Complete Usage</h3> 
- * <p>
- * The suspend/complete style is used when an asynchronous handler is used to 
- * generate the response:
- * </p>
- * <pre>
- * <b>Filter/Servlet:</b>
- *   // when we want to enter asynchronous mode
- *   Continuation continuation = ContinuationSupport.getContinuation(request);
- *   continuation.suspend(response); // response may be wrapped
- *   myAsyncHandler.register(continuation);
- *   return; // or continuation.undispatch();
- *
- * <b>Wrapping Filter:</b>
- *   // any filter that had wrapped the response should be implemented like:
- *   try
- *   {
- *     chain.doFilter(request,wrappedResponse);
- *   }
- *   finally
- *   {
- *     if (!continuation.isResponseWrapped())
- *       wrappedResponse.finish()
- *     else
- *       continuation.addContinuationListener(myCompleteListener)
- *   }
- *
- * async wait ...
- *
- * <b>Async Handler:</b>
- *   // when the async event happens
- *   continuation.getServletResponse().getOutputStream().write(process(event));
- *   continuation.complete()
- * </pre>
- * 
- * <h1>Continuation Timeout</h1>
- * <p>
- * If a continuation is suspended, but neither {@link #complete()} or {@link #resume()} is
- * called during the period set by {@link #setTimeout(long)}, then the continuation will
- * expire and {@link #isExpired()} will return true. 
- * </p>
- * <p>
- * When a continuation expires, the {@link ContinuationListener#onTimeout(Continuation)}
- * method is called on any {@link ContinuationListener} that has been registered via the
- * {@link #addContinuationListener(ContinuationListener)} method. The onTimeout handlers 
- * may write a response and call {@link #complete()}. If {@link #complete()} is not called, 
- * then the container will redispatch the request as if {@link #resume()} had been called,
- * except that {@link #isExpired()} will be true and {@link #isResumed()} will be false.
- * </p>
- * 
- * @see ContinuationSupport
- * @see ContinuationListener
