Hello Mark et all, I referred the source of the class (FOr API etc) of the built-in evaluator below :
*org.drools.core.base.evaluators.MatchesEvaluatorsDefinition* and* drools.packagebuilder.conf* It was a breeze, took me less than 10 minutes! As Mark Proctor mentioned, lots of plumbing has been taken care of in 6.1 and actually this port was really nice and easy. I was able to port my old *inlist*operator from Drools 5.3 to 6.1 Now I am willing to recommend my client to use Drools 6.x for our forth coming major initiative. We have a custom in-house built Rule Engine which I am trying to replace with Drools. The "Custom Evaluator" is a major thing for as as all its really powerful and all the analysts need this. Without this *inlist<.b> operator I am not going anywhere with Drools with my client.* We will be processing in excess of 30 million FACTS*, (Stateless Session) using Drools when I am done converting the project to use Drools!
