Hi,
was just browsing through tomcat code, and the following is just a
mystery to me ->StandardSession.fireSessionsEvent(type,data):
public void fireSessionEvent(String type, Object data) {
if (listeners.size() < 1)
return;
SessionEvent event = new SessionEvent(this, type, data);
SessionListener list[] = new SessionListener[0];
--------> WHY synchronized?
probably someone reported a concurrent modification exception,
synchronized (listeners) {
list = (SessionListener[]) listeners.toArray(list);
}
for (int i = 0; i < list.length; i++){
((SessionListener) list[i]).sessionEvent(event);
}
}
can someone enlighten me? :-)
Another question, are there any plans to bring generics into tomcat
code? /**
* The session event listeners for this Session.
*/
protected transient ArrayList<SessionListener> listeners = new
ArrayList<SessionListener>();
could make the code easier to understand, i would volunteer the work force.
its done here and there as we change code
FIlip
regards
Leon
