Proactor pattern
Proactor is a software design pattern for Event handling in which an long running activities are running in an asynchronous part. A Completion Handler is called after the asynchronous part has terminated.
Interaction
Operation specific actors:
- The Proactive Initiator starts the asynchronous operation via the Asynchronous Operation Processor and defines the Completion Handler
- Completion Handler is a call at the end of the operation from the Asynchronous Operation Processor
- Asynchronous Operation
Standardized actors
- The Asynchronous Operation Processor controls the whole asynchronous operation
- The Completion Dispatcher handles the call , depending on the execution environment.
