Hi all,
Is it possible to determine the Pattern that ‘produced’ a given Fact? For
example, assuming we have the following rule and event handler:
rule r1
when
p1:Person(...)
p2:Person(...)
then
...
end
protected class MyAgendaEventHandler extends
DefaultAgendaEventListener {
@Override
public void
afterActivationFired(org.drools.event.rule.AfterActivationFiredEvent event)
{
String ruleName = event.getActivation().getRule().getName();
KnowledgeRuntime knowledgeRuntime = event.getKnowledgeRuntime();
for (FactHandle factHandle :
event.getActivation().getFactHandles()) {
Object fact = knowledgeRuntime.getObject(factHandle);
Pattern pattern= ?;
}
}
}
Is it possible to determine the Pattern that originate a Person object? If
yes, how the pattern is identified?
Thanks, David
