I want to write a rule that says "Find all long-eared dogs that do not have
short, black hair". This seems like the simple way to do it:
collect( Dog( ears=="long", not (hair=="short" && color=="black") )
But that doesn't parse. Some digging through the archives unearthed a mention
of De Morgan
I am not sure if anyone else is having this issue or not, but I can not do
in-line attribute compares to null.
For instance.
when
ObjectA(
objectBKey == null
)
then
objectBKey is a String in this case.
This doesn't evaluate properly as the rule was firing even though the slot

rule would fail with an exception because i have defined a java "short" type
for the variable "vshort" and the value "99" is too large for a short
type. but now this rule will execute without exceptions. is it
Hi Brian,

If you want to monitor a local dir try using the "dir" property instead
of "url". In your case you would then have something like:
Ok. I put that in but I'm having trouble getting it to recognize the uri I'm
passing in. I'm passing in
"file:///c:/svn/code/sleuth/src/net/intellidata/sleuth/description/rules/"
and I'm getting the following exception:

The decision table mandates atleast one condition. I have faced this problem
before. Assuming you always have some +ve value for cheese.price, do you want
to try following?
RuleSet

Hi there,
is there a way to "reset" the working memory so that all the rules are
run again when fireAllRules() is called?
I know that normaly rules will only be run again when there was a change
and the fact was updated. but in my case I like to run all rules again
in some situations without
hi,
I have no problem for this kind of rule :
rule "Primitive support"
when
$c : Cheese( price < 10 )
then
$c.setPrice( 10 )
end
but I would like to know what is the decision table for this small rule
rule "Primitive support"
when
If you cannot combine the rules into new rules I would suggest looking at
rule flow.

Hi,

All facts are matched against all patterns upon insertion into working

activations (i.e. RHS) not pattern matching.
I think (but it's a vague recollection) however that the sequence of
patterns has an affect (so you want most re
