所有已实现的接口:

AsyncListener, EventListener

public class StandardServletAsyncWebRequest
extends AsyncWebRequest
implements AsyncListener

A Servlet implementation of AsyncWebRequest.

The servlet and all filters involved in an async request must have async support enabled using the Servlet API or by adding an <async-supported>true</async-supported> element to servlet and filter declarations in web.xml.

StandardServletAsyncWebRequest

public StandardServletAsyncWebRequest(ServletRequestContext context)

StandardServletAsyncWebRequest

public StandardServletAsyncWebRequest(HttpServletRequest request,
 HttpServletResponse response)

Create a new instance for the given request/response pair.

参数:

request - current HTTP request

response - current HTTP response

方法详细资料

isAsyncStarted

public boolean isAsyncStarted()

从类复制的说明: AsyncWebRequest

Whether the request is in async mode following a call to AsyncWebRequest.startAsync(). Returns "false" if asynchronous processing never started, has completed, or the request was dispatched for further processing.

指定者:

isAsyncStarted 在类中 AsyncWebRequest

startAsync

public void startAsync()

从类复制的说明: AsyncWebRequest

Mark the start of asynchronous request processing so that when the main processing thread exits, the response remains open for further processing in another thread.

指定者:

startAsync 在类中 AsyncWebRequest

dispatch

public void dispatch(Object concurrentResult)

从类复制的说明: AsyncWebRequest

Dispatch the request to the container in order to resume processing after concurrent execution in an application thread.

指定者:

dispatch 在类中 AsyncWebRequest

onStartAsync

public void onStartAsync(AsyncEvent event)

指定者:

onStartAsync 在接口中 AsyncListener

onError

public void onError(AsyncEvent event)

onTimeout

public void onTimeout(AsyncEvent event)
               throws IOException

指定者:

onTimeout 在接口中 AsyncListener

抛出:
