Re: [rules-users] String comparison question

Try like this..it's working fine.

$c :CashMemoDtl(articleCode:articleCode)
eval($c.getArticleCode().equals( Laptop)$c.getArticleCode().equals(
Mouse)  )

Thanks,

 Hey guys,

 I read in a previous post that == in Drools 4.0.7 maps to .equals()
 automatically. My situation required me to put a String object into the
 working memory and do a comparison on it to see if a particular word is in
 the passed String sentence. Could anybody please guide me as to how to
 approach this problem? Thanks in advance. Here's my original code:


 rule Find Alpha in a sentence
 *

 salience
 * 100

 wrap: WrapperClass(Sentence == Alpha)

 then

 System.out.*println*(Aha found ya!);

 end

   Drools 5 implements a completely new propagation algorithm that

   But for 4.0.x, if you are a community user, best you can do is open a
 JIRA with a test case to reproduce your problem. If we release a 4.0.8
 version, we can fix your issue there, but at this moment we don't know if
 there will be a 4.0.8 release or if the next release will be 5.0.
   If you are a Drools subscriber at Red Hat, then you can simply open a
 support case there and they will fix and provide a patch for you.

 Thanks Edson,

 but the collections do return an empty collection. hm, I just tested this
 ones again and it worked fine. no exception when the set was empty. I will
 keep an eye on this and test some more but seems to work now for me.

 and for the other problem I then hope for 5.0 :).

 and what about the last problem I described before?

 best regards
 Sibylle

   Sibylle,

   Unfortunately, this is the way it was implemented to be, under a
 kind-of fail-fast philosophy we were following. I do think there is value
 in changing things in 5.0 so that, for instance:

 ProcessModel($activities : activities) from $models

   Simply does not match, instead of raises a CCE, in case the model is a
 TypeModel.
   But for 4.0.x, that is how things work.

The only suggestion I can give you is, in your second problem, to not
 return null on your collections. Simply return empty collections:

 class Project {
   ...
   public List getModels() {
if( this.models == null ) {
return Collections.emptyList();
}
return this.models;
   }
   ...
 }
 This is usually a good thing, unless you have a specific semantics
 for null collections in your domain model.

 2008/6/6 Sibylle Duerr [EMAIL PROTECTED]:

Hi there,

I have three issues, where I'm not sure if these are bugs in
drools, or if this is just the way it has to be.

the used classes in this case are:

Project
Model
ProcessModel extends Model

only the Project is in the working memory, because I didn't want
to load all elements due to performance issues (there can be
thousends of elements to load at startup).

if I have the following rule:

Project($models : models)
ProcessModel($activities : activities) from $models

there happen to be two problems. if the project does not only
contain ProcessModels but also TypeModels or others (all extend
Model), this leads to a ClassCastException.
I can solve this by writing the rule as follows:

Project($models : models)
$m : Model(eval($m instanceof ProcessModel)) from $models
ProcessModel($activities : activities) from $m

but this is not really nice and I hope there is a better solution
for this, is there?

the second problem this rule gives me, is when the set 'models' is
empty. that will also throw an exception. to solve this I write:

$p : Project(eval($p.hasModels()), $models : models)
$m : Model(eval($m instanceof ProcessModel)) from $models
ProcessModel($activities : activities) from $m

and I need to use this in each case where I have possible empty sets.


the last problem I encountered when I tried to load all elements
to the working memory and then redefine some rules. used classes:

Aggregation extends DomainElement

rule:

Aggregation(owner.owner != type.owner)

causes some exception. the root exception is a ClassCastException:
ProxyShadowProxy cannot be cast to Aggregation.
when I rewrite the rule as:

$element : DomainElement(eval($element instanceof Aggregation))
Aggregation(owner.owner != type.owner) from $element

everything works fine. but that again is not a nice solution.

any help?

best regards
sibylle

Thanks for replay Chri.

in present product is writting rules validating fields related to table.In
this case i writting diff rules.like this is length rule it's working ...

rule name.lengthRule:[insert][update][ui]
 when
  There is an Category
  Category name length is greater than 8
  //CategoryBean($catid:catid,$name:name,$descn:descn)
  //CategoryBean(name != null, eval(name.length()  8) )
  then
  Reject with response : name length must be less than 8
//ruleViolationMap.put(drools.getRule().getName(),name length must be less
than 80); if(!isSuppressMode){ drools.halt(); }
end

  now i am trying write diff rules like email,zipcode,credit card
  i am trying to use regular expressions.In this case negativeTestCases also
Build Success.like this...suppose i am set in to the value like ..
bean.setEmail(@chnati);
in this cases actuly Build failure in our testcases.But,this time also Build
Success.

[*][]Order email address checking for first letter= OrderBean(email matches
@[A-Za-z0-9]*)

If any possiable give me the related code email,zipcode,phone number.ASAP...

 Chanti,
 what exactly is your question?
 I think that checking zipcode and credit card formats is easier to do in
 java than with rules. Rules are more efficient in more complex situations,
 like when you have multiple objects that need to meet various conditions.

 Yeah, but that's not a drools issue any more. I guess your regexp is not
 sufficient to catch an email address.
 The rule will fire when you provide @aa but it will not fire if you use @
 aa.com, right? google for Validate an Email Address and you will find
 regexps which will handle the dot and other chars.
