Subject: Re: [rules-users] Changeset does not monitor folder correctly
I wrote a small test for loading your drl files with different change sets,
and both methods worked fine and the rules executed the same way for both.
I don't have time today to do a more extensive test.
my change sets are:
http://drools.org/drools-5.0/change-set";
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance";
xs:schemaLocation="http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd";>
and for the directory one:
http://drools.org/drools-5.0/change-set";
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance";
xs:schemaLocation="http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd";>
source for my test is:
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent("myagent");
kagent.applyChangeSet(ResourceFactory.newFileResource(
"C:/rules/resources/ChangeSetDrl.xml"));
KnowledgeBase kbase = kagent.getKnowledgeBase();
StatelessKnowledgeSession ksession =
kbase.newStatelessKnowledgeSession();
Patient p = new Patient();
p.setCreateDate(new Date());
p.setUserId(5);
System.out.println("START EXECUTE WITH DRL CHANGE SET");
ksession.execute(p);
kagent.dispose();
System.out.println("END EXECUTE WITH DRL CHANGE SET");
kagent = KnowledgeAgentFactory.newKnowledgeAgent("myagent");
kagent.applyChangeSet(ResourceFactory.newFileResource(
"C:/rules/resources/ChangeSetDir.xml"));
kbase = kagent.getKnowledgeBase();
ksession = kbase.newStatelessKnowledgeSession();
p = new Patient();
p.setCreateDate(new Date());
p.setUserId(5);
System.out.println("START EXECUTE WITH DIRECTORY CHANGE SET");
ksession.execute(p);
System.out.println("END EXECUTE WITH DIRECTORY CHANGE SET");
kagent.dispose();
and the output from the test is:
START EXECUTE WITH DRL CHANGE SET
User 5 Fri Sep 23 15:26:16 PDT 2011 (package test)
Patient 5 Fri Sep 23 15:26:16 PDT 2011(package test)

Re: [rules-users] accumulate function
I'm assuming that c6066 is really a number and not a stringif not you will
need to change this to parse the string into a number.
I think something like this should do it. You first get the list from a
SegmentGroup8 then sum the values you need. This is untested code.
$seg: SegmentGroup8()
$sum: Number() from accumulate( $cntTotal: ControlTotal() from $seg.getCnt(),
sum($cntTotal.getC6066()))

[rules-users] Changeset does not monitor folder correctly
Hi, I'm trying to use a change set to monitor a folder for drl files but I can't get it to work right. If I list all the files in the folder all the rules load correctly and everything thing is happy. If I just specify a folder the mapping resource are associating rules from the test-two.drl file with the test.drl file. Also the 'KnowledgeAgent adding' adds two test.two (which is the package for the test-two.drl file) instead of a test and a test.two. Which is what happens when I list the files in the change-set. >From the documentation it seems like this should work. Has anyone run into this before? What am I doing wrong? I'm using 5.2.0.M1.

Re: [rules-users] Collect with same value
I'm still not sure I can make my rule work like that. Sorry, my real problem is a little more complicated then I initially described. We are trying to detect if some set of conditions stay within a set of ranges over a period of time. So still using the example below. The color is really the key for the shape and the size can change over time. For example, we would want to know if any shape's size was larger than 5 for 20 min. I see how you are making a map that would have a list of all the shapes of the same color. So $map['BLUE'] would return all shapes and $shape: Shapes( $color: color, size > 5 ) could change to $shape: Shapes( $color: color, size > 5 ) over window:time(20m) to only get Shape sizes for the last 20 min. now this would be a map where the key would be the color and the value would be the min size over a 20 min window. //untested $map: Map() from accumulate ( $shape: Shapes( $color: color) over window:time(20m), init( Map m = new HashMap(); ), action( Number min = m.get( $color ); if( min == null ) m.put($shape.size); else if (min > $shape.size) m.put($shape.size);), result( m ) ) and then I would need to iterate through the map and find all the ones whose min size > 5? -- View this message in context: http://drools.46999.n3.nabble.com/Collect-with-same-value-tp3242904p3245580.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

I think normally setGlobal variables are only used when you want to be able to call back out to the java code again. (I'm not an expert by any stretch so please take that with a grain of salt.) So you might be able to just insert the list. I'm going to assume the List is really List if that is not true please let me know. what about something like this?

[rules-users] Absence Pattern question
Hi, I'm having trouble writing an absence pattern. What I'm trying to do is detect when there is an A followed by no Bs for 3+minutes. I don't care if there is more than one A. What I'm running into is that when I try to use 'over window:time' the time within drools is the end time of the window. So this means I need to write the no Bs for 3+ min first: not( $b: B() over window:time(3m)) then try to find the A before it: $now: Long() from RuleUtilityFunctions.getSessionClockTime() $a: A( this before [3m] $now) then I should have to check to make sure that I don't have any Bs between $a's time and the start of the no B window: not( B( time >= $a.time, time <= $now)) This is not working. I think that it has something to do with my function to get the session clock time (RuleUtilityFunctions.getSessionClockTime()) and how things get evaluated within the Rete engine. Because it does not seem like $now is getting re-evaluated on future calls that pass the $b condition. If I replace $now with the call to getSessionClockTime() everything just seems to get weird. I've tried to write the rule forward too. Look for A followed by no B but that does not seem to work because A is matched at the current time and the rule triggers because there is no B because the future B data has not be inserted into working memory yet. What is the right way to write this rule? Is there a way to get the start and end time of the time window that met the over window:time() condition?

Thank you, That sounds like a good idea if we could automatically fix the data or the rules were more fatal instead of warn/error level, but in our case it will require some human intervention and I don't think we will want to stop everything until it gets fixed.

Re: [rules-users] FW: Basic rules question
Abhay,
You can use the normal Java gets (if your object has them).
when
$prod : Product ($prod.getMemory().getRam().getType() == "DDR")...
instead of $prod.getMemory()... you I think should also be able to use
'this.getMemory()'
(I have not tried these out to make sure)

OK. Another one. How do I access and use a property of a member variable (
object ) of an object, in rules ?
e.g. in the same example, I need to check
1) if a product of type ‘laptop’ is inserted in memory AND
2) if the product’s MEMORY property ( object ) has an object of type DDR ram
attached.
In other words, here is the relationship of facts -
PRODUCT has member variable MEMORY ( which is an object )
MEMORY has member variable RAM ( which is again an object )
RAM has member variable TYPE ( which should be equal to “DDR” )
From within rules ‘when’ part, how do I check if there is a PRODUCT inserted in
memory whose MEMORY has a RAM of type DDR assigned ?

Mike,
What I meant was, There are say 10 objects of RAM in memory whose type is DDR.
Now my “Product” object has a member variable named “compatibleRAMs”, and I
would like to set an arraylist containing these 10 objects to the
“compatibleRAMs” variable of “Product” object in memory.
I am reading about the “collect” which can be used to create collections from
fact objects in memory. Something like.
When
$prod : Product (type==’laptop’)
$compatibleRAMs : ArrayList() from collect (RAM (type == ‘DDR’))
Then
$prod.setCompatibleRAMs($compatibleRAMs);
Am I on the right track ?

Abhay,
Do you need a list?
You can assign RAM to COMPUTERS with this:-
when
$c : Computer( $type : type )
$r : RAM( compatibleWith == $type )
then
$c.addRAM( $r );
end
This would add all RAM (in Working Memory) compatible with COMPUTER to computer.
You could use a list of RAM as a Fact in WM and change your rule to use that:-
when
$l : MyList( )
$c : Computer( $type : type )
$r : RAM( compatibleWith == $type ) from $l
then
$c.addRAM( $r );
end
Or you can define a rule to construct the list too:-
when
$l : MyList( $t : typeRAM )
RAM( $c : $t )
then
$l.add( $r )
end
I assume you'd need to differentiate different lists for different types; so I
have shown use of "MyList" which could subclass ArrayList and have a "Type of
RAM" attribute. Drools doesn't "do" generics.
With kind regards,
Mike

Thanks for helping me out so far.
I have another question. What if I have all my “RAM” objects inserted into
working memory. How should I write my rule’s “when” portion to get a
collection of all the RAM objects matching type “DDR” ? In other words, can I
get collection of facts assigned to a variable and use it in the “then” part ?

[rules-users] Missing results with multiple time rules
Hi, I'm having an issue trying to run multiple time window patterns at the same time. If I run them separately they produce the correct results but when I load them both rules into working memory I only get results for the second one. If I remove the 'over window:time(720ms)' aspect from both rules I do get results for both as expected. The rules right now are very similar (I'm trying to test out how we write drl files) I'm not sure if that has something to do with it or not. In one rule I'm trying to find 3 or more objects that match my constraints over the time window and in the other between 3 and 5 objects. I'm using drools 5.2.0 from last Tuesday droolsjbpm-drools-20c84a4.

If there is a small number it is more straight forward to have a rule for each
one (so the 2nd option). This allows all you logic to be in one place. If
there are a large number of products and writing a rule for each one is

Hi
I am a newbie to rule based applications and trying to get the concept of
rules.
I have couple of questions about rules to start with, not specifically about
Drools though.
Q1 - Should rules be data/model specific or can/should they be generic or both
==
e.g.
If selected product “TYPE” is “laptop”, then category “RAM” should have all
“DDR” type items compatible ( selecting items matching certain property )
OR
If selected product is “IBM T42”, then category “RAM” should have “512MB DDR” ,
“1024MB DDR”, “2048MB DDR” compatible. ( assigning individual items in rules )
OR
Combination of both
Q2 – How should be the data modeled in above case
==
e.g.
in product master, each item ( e.g. T40, T42 ) should have a “TYPE” ( e.g.
desktop or laptop ) , all items in category “RAM” should have a “TYPE” ( e.g.
DDR ) and then control the assignment of RAM options to the PRODUCT through
Rule
using “DDR” type ?
OR
in product master, each item ( e.g. T40, T42 ) should have a “TYPE” ( e.g.
desktop or laptop ) , all items in category “RAM” should have a
“compatibleProduct” column ( e.g. desktop or laptop ) and control the
assignment
of RAM to PRODUCT through “dynamic” rules by selecting all the RAMs by passing
the “TYPE” of the product to the database handler.
Am I making my point clear ?

How many train stops are you talking about? If it is only a few it might not matter if you don't have the many trains. When you are writing your rule if you narrow down by matching schedule first and then comparing all the stops that might help. An alternative to comparing two collections in drools would be to write a custom function that could do some simple checks first like make sure that the size of both lists are the same. Another option if the list of train stops is a POJO itself is to make its hashkey so that two lists with the same values will have matching hashkeys.

If I add "import function MyRuleFunction.exampleImportedFunction;" it works fine but I don't want to have to do that for every function in my file. Functions used in the consequent don't seem to need to be imported specifically (* works fine). Has something changed between 5.1 and 5.2.0.M2 that effects this?
