Install the Imixs-BPMN Modeler to examine the example. The example BPMN model can be downloaded from Github. Internally the Imixs BPMN Rule Engine is based on the Core-RuleEngine which supports various script languages to describe a rule. The workitem can contain any kind of data to be evaluated by the business rules. Model model = BPMNParser.parseModel(inputStream, 'UTF-8') The model instance can either be taken from a running instance of the Imixs-Workflow engine or loaded on demand from the file system: // load BPMN model from input stream Workitem = new ItemCollection().model(MODEL_VERSION).task(100).event(10) Īssert.assertEquals(200, bpmnRuleEngine.eval(workitem)) bpmnRuleEngine=new BPMNRuleEngine(model) To initialize a BPMN Rule Engine a Imixs BPMN Model instance need to be loaded first. The conditional expression is based on JavaScript but other Script languages are also supported. The engine evaluates the data of a given workitem.Ī single condition is defined in a conditional sequence flow. The rules are evaluated as a chain of conditional events. The BPMN Rule Engine provides an easy way to describe also complex business rules based on a visual model. This is a powerful mechanism to describe rules in a BPMN model and evaluate a given workitem. The BPMN Rule Engine uses Conditional Events to evaluate a business rule. With the latest version 5.1.0 the Imixs-Workflow project introduces a BPMN based Rule Engine.
