<br> Glad to hear things are moving forward! <br><br> How do you feel about writing a quick tutorial on how to implement a custom evaluator so that others can benefit from your experience? :) We could post it on the blog and add to the manual with the proper credits.<br>
<br> Regarding your question, "in" is a special parser syntax sugar we have in Drools. So:<br><br>field in ("aValue", $aVariable, Some.CONSTANT)<br><br> Is exactly the same as:<br><br>field == "aValue" || == $aVariable || == Some.CONSTANT<br>
<br> So, the answer is, without patching Drools, unfortunately, it is not possible to do the same with custom evaluators. In your case, the best I can suggest without changing Drools parser is to have your evaluator receive all possible values as a single String:<br>
<br>code codeChecker "V100-V200, 243327005, 243327005"<br><br> So, your operator would just split the list and check all values there as appropriate. Obviously, if you would like to submit a patch for Drools allowing custom evaluators to accept multiple values, we would gladly apply the patch to the code base and support it from that time forward.<br>
<br> Cheers,<br> Edson<br><br><div class="gmail_quote">2010/2/1 kashif10 <span dir="ltr"><<a href="mailto:kash452@yahoo.com">kash452@yahoo.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Thanks all of you!<br>
<br>
We are heading toward the solution.<br>
<br>
i) We start putting interenal data too in WM.<br>
ii) For time period matching I simply write a method in Fact class, which<br>
calls using the exact name matching fucntionality.<br>
iii) For complex code matching including exact number match, Range match,<br>
wildcard match. I created the customEvalutor, usning new operator<br>
codeChecker, to handle all required scenarios, as follows:<br>
<br>
exists (Diagnosis(name == "diag3" || ( code codeChecker "V100-V200" &&<br>
codeSystem == "2.16.840.1.113883.6.96" ) ))<br>
<br>
<br>
Ques: I need suggestion how to use my custom Evaluator codeChecker in<br>
following suggested OR combination using in. As you know that if we don't<br>
use "in" then we have to add so many ORed patterns.<br>
<br>
exists (Diagnosis(name in ( "Vibrio abc splendidus" , "kash") || ( code in<br>
( "243327005", "243327005") && codeSystem == "2.16.840.1.113883.6.96" ) ) )<br>
<br>
