Method Details

add

public static void add(ILongPolling longPolling)

Add long polling object so that it is centrally registered with its id - to be later be picked up by a request from browser side, into which the id is encoded as well.

remove

public static void remove(ILongPolling longPolling)

Please pay attention: thinking about the "remove" is "more important" than thinking about the "add"...! Long polling instances are registered within the session context, as a result the garbage collector will never catch these objects during the lifecycle of a session! The one who adds a long polling object at the same time has to make sure that this instance is removed.

Otherwise not only some memory will be not cleaned up in a proper way, but also one thread may be kept for a long time!

public static void abortAllLongPollingThreadsForSession(javax.servlet.http.HttpSession session)

abortAllLongPollingThreadsForSubpageContext

public static void abortAllLongPollingThreadsForSubpageContext(SubpageContext spc)
