[rules-users] FireAllRules and threads

[Swindells, Thomas]

You'd probably be better to use a batch command though containing the three commands rather than calling the methods on the ksession directly - it makes for slightly cleaner and more reliable integration from my experience.

Hi there,
I've got a question regarding statefull session and threads.
I searched a lot about this topic but I'm still a bit confused so...
When a StatefullSession - fireAllRules() returns, can I be sure that the
entire rules processing has ended?
I red something about the fact that this is true unless rules inference
happens, is it correct?

No. A fireAllRules() returns after all of "inference" has happened and no
more activations are eligible for firing.

My simple purpose is to insert a fact into a statefullsession working
memory, fire rules, wait until the end of rules processing and than retract
that fact.
How can i do it?

FactHandle fh = kSession.insert( object );
kSession.fireAllRules();
kSession.retract( fh);

Thank you
Errico
