Interactive Workflows with Signals and Queries
This lesson focuses on interactive workflows using signals and queries for real-time communication
What's Provided
Starter Materials:
- ✅
workflow/ApprovalWorkflow.kt- Starter interface with signal/query templates - ✅ Basic data classes for approval requests and results
- ✅ Template structure for implementing interactive patterns
What You Need To Do
Follow the instructions in ../modules/lesson_10/workshop_10.md to:
- ✅ Implement the ApprovalWorkflow interface with signals and queries
- ✅ Create workflow implementation that maintains state
- ✅ Handle signal methods for approve/reject actions
