Class ConditionalExpressionEvent

java.lang.Object
org.imixs.workflow.engine.ConditionalExpressionEvent
public class ConditionalExpressionEvent extends Object
CDI Event for conditional expression in BPMN process flows.

This event enables extensibility by allowing registered observers to transform or interpret conditions in a BPMN SequenceFlow before they are evaluated by the RuleEngine. This design pattern decouples the core BPMN engine from specific condition implementations.

In this way observers can implement domain-specific condition logic or track condition evaluations
