Approval Node (type = "approval")

Used for human-in-the-loop approval/to-do scenarios.

Schema

• Node class: ApprovalNode.java
• Executor: ApprovalNodeExecutor.java

Example

Runtime interaction:

• On first execution, if there is no decision:
  • HumanTaskService creates a pending task.
  • returns status = WAITING, and the workflow is suspended.
• After the user acts, an external system calls:

POST /linker/task/human/{taskId}/complete

• On resume:
  • ApprovalNodeExecutor completes the task and writes the decision back to the context.
