Method Detail

getRequest

ServletRequest getRequest()

getResponse

ServletResponse getResponse()

hasOriginalRequestAndResponse

boolean hasOriginalRequestAndResponse()

dispatch

void dispatch()

Throws:

java.lang.IllegalStateException - if this method is called when the request is not in asynchronous mode. The request is in asynchronous mode after ServletRequest.startAsync() or ServletRequest.startAsync(ServletRequest, ServletResponse) has been called and before complete() or any other dispatch() method has been called.

dispatch

void dispatch(java.lang.String path)

Parameters:

path - The path to which the request/response should be dispatched relative to the ServletContext from which this async request was started.

Throws:

java.lang.IllegalStateException - if this method is called when the request is not in asynchronous mode. The request is in asynchronous mode after ServletRequest.startAsync() or ServletRequest.startAsync(ServletRequest, ServletResponse) has been called and before complete() or any other dispatch() method has been called.

dispatch

void dispatch(ServletContext context,
              java.lang.String path)

Parameters:

path - The path to which the request/response should be dispatched relative to the specified ServletContext.

context - The ServletContext to which the request/response should be dispatched.

Throws:

java.lang.IllegalStateException - if this method is called when the request is not in asynchronous mode. The request is in asynchronous mode after ServletRequest.startAsync() or ServletRequest.startAsync(ServletRequest, ServletResponse) has been called and before complete() or any other dispatch() method has been called.

complete

void complete()

start

void start(java.lang.Runnable run)

addListener

void addListener(AsyncListener listener)

addListener

void addListener(AsyncListener listener,
                 ServletRequest request,
                 ServletResponse response)

createListener

<T extends AsyncListener> T createListener(java.lang.Class<T> clazz)
                                    throws ServletException

Throws:

ServletException

setTimeout

void setTimeout(long timeout)

Set the timeout.

Parameters:

timeout - The timeout in milliseconds. 0 or less indicates no timeout.

getTimeout

long getTimeout()
