you no longer need to declare custom accumulators, instead they are specified via imports. See docs, notice the “import” bit.
http://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html/DroolsLanguageReferenceChapter.html#d0e6601 7.8.3.7.4.1. Accumulate CE (preferred syntax) …. The code for the function is very simple, as we could expect, as all the "dirty" integration work is done by the engine. Finally, to use the function in the rules, the author can import it using the "import accumulate" statement: import accumulate <class_name> <function_name> For instance, if one implements the class some.package.VarianceFunction function that implements thevariance function and wants to use it in the rules, he would do the following: Example 7.77. Example of importing and using the custom "variance" accumulate function import accumulate some.package.VarianceFunction variance rule "Calculate Variance" when accumulate( Test( $s : score ), $v : variance( $s ) ) then // the variance of the test scores is $v end On 5 Mar 2014, at 23:13, mattmadhavan <mmadha...@facs.org> wrote: > Hello, > I am still suck on Drools 5.4/5.5 since I have issues with Custom > operators/Evaluators in 5.6. > > I am not able to move to Drools 6.x because the spring configuration is > screwed up.
