Subject RE: [jira] Commented: (DIRMINA-121) Per-port filter chain
Date Thu, 17 Nov 2005 12:37:09 GMT



	From: Trustin Lee [] 

Right, there's no need to remember NextFilter with getNextFilter()
methods.  But it doesn't mean that IoFilterChain can update the
reference to NextFilter in runtime because it will raise concurrency
issue definitely. 

Whatever concurrency issues are here, we have them in the code today, as
I am not changing the API and a session can modify its chain any time it
wants. Even when still processing the previous event on a separate
thread, a session-thread can start changing its chain and hence
modifying NextFilter on another thread.


Not sure what you want to do about it.
