Rule 'Working Students' salience -10 when IStudent s = don( $p, IStudent.class, true ) IWorker w = don( $p, IWorker.class, true ) Will find an example around classifications of students and workers. In theĭrools-examples source project open the classes and drl for the namespace '/org/drools/examples/traits'. Release adds an example so that people have something simple to run, to help them understand.

Traits were introduced in the 5.3 release, and details on them can be found in the N&N for there. Note, of course, that the activation of a named consequence not guarded byĪny condition with break doesn't make sense (and generates a compile time error) since otherwise the LHS part In fact do just schedules a consequence in the agenda,Īllowing the remaining part of the LHS to continue of being evaluated as per normal, while break also blocks anyįurther pattern matching evaluation. 'giveDiscount5' using the keyword break instead of do. This result is achieved by activating the consequence named

Here the purpose is to give a 10% discount AND a free parking to Golden customers over 60, but only a 5%ĭiscount (without free parking) to the Silver ones. To verbose and difficult to be maintained repetitions like in the following example: rule 'Give 10% discount to customers older than 60' Sometimes the constraint of having one single consequence for each rule can be somewhat limiting and leads Objects (and their totals per constraint) are available directly on the ScoreDirector API.įor more information, see the blog post and the You also no longer need to hack the API's to get a list of all ConstraintOcurrence's: the ConstraintMatch Drools automatically exposes the kcontext variable in the RHS, so you Out it itself through the kcontext variable. Notice that you don't need to repeat the ruleName or the causes (the lectures) no more. addHardConstraintMatch ( kcontext, - 1 ) end HARD, - 1, $leftLecture, $rightLecture )) endĪfter: rule 'conflictingLecturesSameCourseInSamePeriod' when. then insertLogical ( new IntConstraintOccurrence ( 'conflictingLecturesSameCourseInSamePeriod', ConstraintType. It's much harder to cause score corruption in your DRL.īefore: rule 'conflictingLecturesSameCourseInSamePeriod' when. Faster: the average calculate count per seconds increases between 7% and 40% on average per useįar less error-prone.
