Re: [rules-users] Drools 6.x and Custom Operators(Evaluators) and Accumulators - Using them as regular functions?

Hi Mark, My apologies if I am not clear with my question. I am looking for a way to create and use my own custom evaluator. (I know its similar to custom evaluator) I have a written a custom eval operator called *inlist* that will look to see if the left hand is in a range of values as follows: This function again encapsulates a very powerful RegEx utility method my co-worker created: when customer:Customer (cancerType == "THYROID" && age *inlist *(10-20, 30- 45, 50, 52, 57-60) then ......................... Note that this works only for Drools 5.3, I could not make it to work for 5.6 due to API compatibility. And I have no idea how to implement this in Drools 6.x. (I used to spring to configure this) I doubt I am the only one out there who has a need to write a Custom evaluator. Another question is if I follow the sane syntax as the custom accumulator - can I use the function on the right hand side. How do I get my operands etc. I appreciate your help in advance! Any ideas please? Thanks Matt'M -- View this message in context: http://drools.46999.n3.nabble.com/Drools-6-x-and-Custom-Operators-Evaluat...
