Re: [rules-users] Apply role to whole class hierarchy

2012-07-27 Thread Joerg Henne

Thanks for your help, Edson!

We are using drools 5.4.0.Final via maven. 

Maybe I am missing something, so here's a quick overview of what we do. We
have a model class ButtonEvent which is derived like this: 
ButtonEvent -> ZonedEvent -> VSCPEvent

Then there's a rulebase with something like this:

import test.vscp.VSCPEvent;
import test.vscp.information.ButtonEvent;

declare VSCPEvent
@role( event )
@timestamp( timestamp )
@expires( 1h )
end
declare ButtonEvent
@role( event )
@timestamp( timestamp )
@expires( 1h )
end

rule "Button long pressed"
when
b : ButtonEvent( action == Action.PRESSED )
not( ButtonEvent( action == Action.RELEASED, this after[0s,1s] b ) )
then
...
end

What I would have expected is that the second 'declare' statement to be
unnecessary. However, if I take it away, this is what I get:

java.lang.ClassCastException: org.drools.common.DefaultFactHandle
at
org.drools.base.evaluators.AfterEvaluatorDefinition$AfterEvaluator.evaluateCachedRight(AfterEvaluatorDefinition.java:316)

Re: [rules-users] Guvnor: Accessing Bound Variable in "Then" Statement

2012-07-27 Thread Michael Anstis

Hello,

Please advise which version of Guvnor you are using.

Please also provide a few explicit examples where behavior is not as you'd
expect (screen shots of the rule and a few words would be cool).

Thanks,

[rules-users] [Planner][DRL] Changable problem facts?

2012-07-27 Thread mSkiba

Hello!

I am working on task scheduling system. My system works fine, but I want to
make it faster. For my current problem we can assume that my domain consists
of:

* Worker (int id, List workingHours)
* TaskAssignment (int id, List possibleExecutionTime, Duration
leadTime, Worker worker)

I am trying to assing each Task Assignment to 1 worker. It's obvious. All I
need to do is to make my rules computing faster. For example I have a rule:

rule "ASSIGN_OUT_OF_WORKING_TIME"
when
$w : Worker($id : id != 0, $wh : workingHours)
$ta : TaskAssignment(worker != null, worker.id == $id)
not TimePeriod( isBetweenInclusive($ta.getTimeSlot()),
isBetweenInclusive($ta.getEndTimeSlot()) ) from $wh
then
insertLogical(new 
IntConstraintOccurrence("ASSIGN_OUT_OF_WORKING_TIME",
ConstraintType.NEGATIVE_HARD, 
100, $w ));
end

This rule checks if every TaskAssignment assigned to a Worker lies in the
worker's working hours. The problem is that score calculator is trying to
pair given Worker with every TaskAssignment. So I have to make set of
TaskAssignment as small as possible. I can acquire that by storing in a
Worker any kind of Set including all assigned TaskAssignments. After this my
domain should looks like this:

* Worker (int id, List workingHours, Set
cashedTaskAssignments)
* TaskAssignment (int id, List possibleExecutionTime, Duration
leadTime, Worker worker)

and my rule:

rule "ASSIGN_OUT_OF_WORKING_TIME"
when
$w : Worker($id : id != 0, $wh : workingHours, *$cta :
cachedTaskAssignments*)
$ta : TaskAssignment() *from $cta*
not TimePeriod( isBetweenInclusive($ta.getTimeSlot()),
isBetweenInclusive($ta.getEndTimeSlot()) ) from $wh
then
insertLogical(new 
IntConstraintOccurrence("ASSIGN_OUT_OF_WORKING_TIME",
ConstraintType.NEGATIVE_HARD, 
ASSIGN_OUT_OF_WORKING_TIME, $w ));
end

My cloneSolution() method is cloning everything right (deep clone of every
TaskAssignment and Worker). I've checked it via many tests. Anyways I'm
getting:
*Score corruption: the workingScore (-1800hard/0soft) is not the
uncorruptedScore (-1904hard/0soft):*
or similar error.

To sum up:
* my system works fine without any changes in Worker class
* I want to make it faster by caching assigned TaskAssignments in a Worker
objects
* I'm getting 'Score corruption' error

Is my idea possible to play out?

No exact date for 5.5.0.Beta1 has been set yet: Planner follows Drools's

That selector functionality is ready to be released though, so it will 
be part of the next release.

apparently there is something else going on:

Hi,

It is not quite clear to me what you are actually having problems with. I
think the documentation explains it quite nicely.

See section 6.2 Templates

http://docs.jboss.org/drools/release/5.4.0.CR1/drools-expert-docs/html_single/index.html#d0e7468

If you have a more specific question. Feel free to ask.

Regard,
Frank

Re: [rules-users] Using global variable in DRL file

2012-07-27 Thread Wolfgang Laun

Ah, yes - there are multiple updates of an Agent from several
different policies.

Now, it depend: Is the computed sum of the APEs in the Agent used in
any other rule? If not, the solution is simple. Do not use
modify/update; simply accumulate the values, using the setter, and in
this case you can even omit the no-loop.

rule "accumulate policy APEs into agent APE"
when
$csvAgent : CSVBeanAgent( $agno: agentNo, $agAPE: agentAPE )
$csvPolicy : CSVBeanPolicy( agentNo == $agno, $polAPE: policyAPE )
then
$csvAgent.setAgentAPE(  $agAPE + $polAPE );
end

If you do need the updated CSVBeanAgent.agentAPE, it's a little more
complicated and I should test the solution before I post it. - Or if
you want to try untested: you'll need an accumulate, like this:

rule "accumulate policy APEs into agent APE"
no-loop true
when
$csvAgent : CSVBeanAgent( $agno: agentNo, $agAPE: agentAPE )
accumulate( CSVBeanPolicy( agentNo == $agno, $polAPE: policyAPE );
 $sum: sum(  $polAPE ) )
then
 modify( $csvAgent ){ setAgentAPE( $sum ) }
end

Note that this assumes that the old value in agentAPE is 0 or can be
overwritten; otherwise you might need to add the old value to the
$sum.

Re: [rules-users] Rule Templates

2012-07-27 Thread FrankVhh

>The information that would help me is (using Eclipse or JBDS) can one edit, 
It depends if you mean edit the templates or edit the data that you use to
populate it.

You can create a rule template in any text editor you like and, AFAIK, it
can have any extension you prefer. Convert it to an inputstream and use it
in the code as is documented.

Regarding the data source, you have multiple options to collect the data.
Editing this data depends a bit on the type you are using. I typically
convert xml objects to java objects and use (and, sometimes, abuse) them to
fill the template and "generate" rules. 

>compile to drl 
Compile to drl is done using the code as documented.

String drl = converter.compile( objs, templateStream );

You can do with the String whatever you like. use it to feed a
knowledgebuilder directly, or write it to a file.

>and test the rule templates
Again. This depends on what you mean. If test the rule templates means:
"check whether it generates a correct drl", than there are 2 things you can
do.
1) Manually check that the rules are as you expect them to be.
2) Verify that the drl compiles in a knowledgebuilder.

If "test" means, check whether my generated rules can construct a correct
decision, then you wikk have to set up a service/a method/ a unit test in
which you use the rules to create a knowledge base and which takes input
data to generate a certain output.

If you want, you can use guvnor to create test scenarios or implement a
testing tool by your own.

Frank
