hi,
i have a rule file as follows:
declare Event
@role( event )
end
declare window Ticks
Event()
over window:time(1m )
end
rule "More than 5 file added events"
when
$p: RuleContext()
Number(intValue > 4) from
accumulate( $e :Event (name == "new file added") from window Ticks,
count($e) )
then
Event event = new Event("too many files added last
minute",$p.getOldContext().getParent(),new
Date());
event.display();
end
this rule gets fired only if i add more than 4 files all at once..
say if i add first 2 files within the first 10 seconds, next two files
after the 20th second and next two files after 40th second, this rule is
not getting fired.. ( there are 6 file added events in the window over past
1 min and the rule should have got fired ). what is the problem with the
current rules and how can i modify it to meet my requirement?
Thanks.

Is there any documentation snippet that says you can declare a fact
(not even an event) like this, restricting its existence?
If not, why does this not cause an compilation error?

i found this type of declaration in a site and thought this is allowed..
also it doesnt throw any compilation error and works the same way as
declared like this:
accumulate( $e :Event (name == "new file added") *over window : time(1m)*,
count($e)

It is possible to declare sliding windows
A possible problem (I didn't check the logic) is that
you are not inserting the new Events you create.

no, actually i think the problem is because, i create a new session once in
10 seconds and dispose it off. so when i create the first two files in
first 10 seconds , the session is disposed, and in the next session the
next two files are created and disposed.. like this it goes.. so when i
create more than 4 files all at the same instant it falls under the same
session and the sliding window works..
could this be the problem?

All the context of a session, including the windows, goes away when the
session is disposed.
In general, please try to post all your DRL and as much information you
can on how the
sessions are built and managed. That makes it easier to understand what
is going on.
Thanks!
