Hi all,
I added a return type to ExecutionListener#notify, allowing execution listeners to interact with the engine. Currenly, listeners are allowed to request the following:
1. Delay node execution: Only valid for NODE_TOKEN_ACCEPTED event. Skips the actual execution of the node. We can use this later to implement delayed execution of nodes based on timer.
2. Delay process completion: Only valid for PROCESS_COMPLETED events. Leaves the process is in PENDING_COMPLETE state. I use this to do some asynchronous processing on process completion, which then calls finalizeComplete when it's done.
3. Delay process cancellation: Only valid for PROCESS_CANCELED events. See #2.
If anyone sees any issues with the implementation or see other ways in which this could be useful, let me know.
cheers,
Paul
