I am using a pool of Rete objects in my application, i've just discovered and
issue where the my cleanup function seem to intermittently 'miss' a few
definstances. Here's the Java code:
--
public void passivateObject(Object object) throws Exception {
// undef all the java stuff
logger.debug("Passivating rete engine, removing all definstances and
resetting");
Rete engine = (Rete)object;
Iterator i = engine.listDefinstances();
while (i.hasNext())
{
Object instance = i.next();
logger.debug("Instance Type: " + instance.getClass().getName());
engine.undefinstance(instance);
}
((Rete)object).reset();
super.passivateObject(object);
}
--
With (watch all), I can see the instance facts being removed from working
memory. However, for some reason sometimes the Iterator does not seem to get
all of them. When the reset is called, I see the initial fact get asserted
along with the 'missed' definstances. There doesn't seem to be much rhyme or
reason with this issue, it happens from time to time but I can't seem to nail
down why.
Is Rete.listDefinstances() a reliable way to get all of my definstance facts ?
