Execution Plan for Extended Analysis

Phase 1: Foundation (Current Topic)

• Define the TriggerPoint and TriggerContext models.
• Implement TriggerDetector interface.
• Create TriggerAggregator to coordinate multiple detectors.

Phase 2: Direct Trigger Detection

• Implement GenericEventDetector using ASTVisitor to find sendEvent calls.
• Enhance CodebaseContext to provide mapping from MethodDeclaration to its callers (within the same codebase).

Phase 3: Entry Point Mapping

• Implement SpringMvcDetector for REST endpoints.
• Implement MessageListenerDetector for Kafka/JMS.
• Implement ConfigurableTriggerDetector for user-defined patterns.

Phase 4: Call Graph Integration

• Develop a simple call graph builder to link Entry Points to Trigger Points via intermediate service calls.
• Support inheritance in call graph resolution (e.g., calling a method defined in an interface/base class).

Phase 5: Correlation and Visualization

• Update ExportService to include trigger information.
• Update DOT exporter to show "external" entry points as boxes pointing to transitions.
• Update SCXML exporter to include trigger metadata in <transition> tags.

Phase 6: Validation

• Create a "Complex Sample Project" with REST controllers, services, and multiple state machines.
• Add unit tests for each detector and the aggregator.
• Verify that inheritance in both state machine config and controllers is correctly handled.

Phase 7: Advanced Value Resolution

• Implement PropertyResolver to scan application.properties/yml.
• Add support for @Value tracking in fields and constructors.
• Implement constant resolution for cross-class references in annotations.
• Integrate value propagation into the call graph analysis (linking injected values to sendEvent arguments).
