Re: [rules-users] Help Problem with kind of minimization

2007-05-03 Thread Edson Tirelli


  Ops, copy&paste problem. The correct rule is:

rule "get closer object"
when
   $a : Agent( $num1 : num )
   $b : Poste( $num2 : num )
   not Poste( $num3 : num -> ( abs( $num1, $num3 ) < abs( $num1, $num2 ) )
)
then
   // do something
end

Hi,

If you are using 4.0.0.M2, I think this will do the job:

function abs( int a, int b ) {
return Math.abs( b - a );
}

rule "get closer object"
when
$a : Agent( $num1 : num )
$b : Poste( $num2 : num )
not Poste( $num3 : num -> ( abs( $num1, $num3 ) < Math.abs( $num1,
$num2 ) ) )
then
// do something
end

If you are using 3.0.x, then it would be like:

function abs( Integer a, Integer b ) {
return Math.abs( b.intValue() - a.intValue() );
}

rule "get closer object"
when
$a : Agent( $num1 : num )
$b : Poste( $num2 : num )
not Poste( $num3 : num -> ( abs( $num1, $num3 ) < Math.abs( $num1,
$num2 ) ) )
then
// do something
end

Hope it helps. Let us know if it works the way you need.

Re: [rules-users] ImputDrl

2007-05-03 Thread Alexey Panchenko


Hi Ismail,

1) Make sure .drl file is available thru the classpath
2) Try .class.getResourceAsStream("/Drl/Sample.drl") (with leading slash).
The path is treated as relative without the leading slash.

Hi,

Yes, I was using Drools 3.0.6.

I have opened the JIRA issue http://jira.jboss.com/jira/browse/JBRULES-838
and (hopefully) attached a test to this posting; see readme.txt for
instructions.

If you download the jBoss rules with Dependencies file, it comes with
string-template.jar. Use this.

Re: [rules-users] ImputDrl

sir,
 if you want to take any .drl file as an input of your JAVA program then 
you can try this code,

final Reader source = new InputStreamReader( 
ClassExample.class.getResourceAsStream( "Class.drl" ) );

here ClassExample is corresponding JAVA program of your  Class.drl  file and 
ClassExample is your main class which contain main 

with regards,
Niloy Debnath

[rules-users] Help Problem with kind of minimization

2007-05-03 Thread l'ami molette



Hi, I’m a
new user of JBossRules, and I have difficulties to solve a problem using
jBossRules.

 

I have two
classes (AClass.java & Bclass.java). Each one have a number (an
"int" value (AClass.getNum() & BClass.getNum())

, and I
want to extract a Aclass & a Bclass witch have the closest numbers. In fact
I want to minimize the value:

Math.abs(AClass.getNum()
- BClass.getNum()).

 

I tried to
write a rule like this:

 

rule
"My rule"

when

ACl : Agent ($AClNum :
num , $AClNom : nom)

BCl : Poste ($BClNum :
num , $BClNom : nom)

BCl2 : Poste ()

not Agent($ACl2Num : num
-> (Aminor(CalculAbsolue($ACl2Num.intValue(),BCl2.getNum()) ,
CalculAbsolue($AClNum.intValue(),$BClNum.intValue()) )))

then

System.out.println("Selected
: "+ ACl.getName() +" "+BCl.getName()+" diff: "+
CalculAbsolue(ACl.getNum(),BCl.getNum()));

retract(ACl);

retract(BCl);

end

 

function int CalculAbsolue(int a, int b){

return
Math.abs(b-a);

}



function boolean Aminor(int a, int b){

return
a < b;

}



--> But the rule doesn't work.

Does anyone have an idea to solve my
problem?

Thank you very much for your help.
