Method Detail

resume

void resume()

Complete the HttpServletResponse and finish/commit it.

isSuspended

boolean isSuspended()

Return true if that suspend() has been invoked and set to true

Returns:

true if that suspend() has been invoked and set to true

isResuming

boolean isResuming()

Return true if that resume() has been invoked

Returns:

true if that resume() has been invoked and set to true

suspend

void suspend()

Suspend the HttpServletResponse indefinitely. Suspending a HttpServletResponse will tell the underlying container to avoid recycling objects associated with the current instance, and also to avoid commiting response.

suspend

void suspend(long timeout)

Suspend the HttpServletResponse. Suspending a HttpServletResponse will tell the underlying container to avoid recycling objects associated with the current instance, and also to avoid commiting response.

Parameters:

timeout - The maximum amount of time, in milliseconds, a HttpServletResponse can be suspended. When the timeout expires (because nothing has been written or because the resume() or AtmosphereEvent#cancel()), the HttpServletResponse will be automatically resumed and commited. Usage of any methods of a HttpServletResponse that times out will throw an IllegalStateException.

getRequest

E getRequest()

Return the underlying Request.

Returns:

E the underlying Request.

getResponse

F getResponse()

Return the underlying Response.

Returns:

F the underlying Response.

getServletContext

ServletContext getServletContext()

Return the ServletContext

Returns:

the ServletContext

getBroadcaster

Broadcaster getBroadcaster()

Return the current Broadcaster

setBroadcaster

void setBroadcaster(Broadcaster broadcaster)

Set the current Broadcaster

getWebServerName

String getWebServerName()

Return the WebServer we are running on.

Returns:

Return the WebServer we are running on.

getMessage

Object getMessage()

Return the object that were pass to Broadcaster.broadcast(java.lang.Object)

Returns:

the object that were pass to Broadcaster.broadcast(java.lang.Object)
