/**
* Continuation.
* <p>
* 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>
* <h1>Suspend/Resume Usage</h1>
* <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>
* <h1>Suspend/Complete Usage</h1>
* <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
*
* @deprecated use Servlet 3.0 {@link javax.servlet.AsyncContext} instead

/** ContinuationThrowable
* <p>
* A ContinuationThrowable is throw by {@link Continuation#undispatch()}
* in order to exit the dispatch to a Filter or Servlet. Use of
* ContinuationThrowable is discouraged and it is preferable to
* allow return to be used. ContinuationThrowables should only be
* used when there is a Filter/Servlet which cannot be modified
* to avoid committing a response when {@link Continuation#isSuspended()}
* is true.
* </p>
* <p>
* ContinuationThrowable instances are often reused so that the
* stack trace may be entirely unrelated to the calling stack.
* A real stack trace may be obtained by enabling debug.
* </p>
* <p>
* ContinuationThrowable extends Error as this is more likely
* to be uncaught (or rethrown) by a Filter/Servlet. A ContinuationThrowable
* does not represent and error condition.
* </p>
