Re: [rules-users] Filtering inside the LHS

Hi All, I am seeking some kind of filtering (if statement) inside the LHS. I have the following example rule (note: $attributeFilteredSentences and $cmdescriptor are defined in the extends rule which is not presented): *rule*" choose message sentence example"extends " attributeFilteredSentences collection" *when* SContextState(state == SContextState.ONE) $sentences: ArrayList() *from**collect*(Sentences.Sentence( descriptor.meanings.meaning == $cmdescriptor.meanings.meaning ) *from* $attributeFilteredSentences) *then* logger.info("RULE: entered rule: "+drools.getRule().getName()); //some logic... *end* ** as can be seen I am filtering sentences based on the meanings, and the meaning collection must be identical as in $cmdescriptor (this is the case when SContextState.ONE) Now to my question: I have cases ((this is the case when SContextState.TWO) where I do not need exact validation but rather superset of (for this I have a supersetOf operator implemented) I would like to avoid duplicating this rule (as I have similar condition in many other rules) and being able to filter once with "==" and once with "supersetOf" depending on the SContextState.

Any ideas how to do this? Thanks, Hezi _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
