Proactor pattern
Proactor is a design [pattern (computer science)|software design pattern] for event handling in which long running activities are running in an asynchronous part. A completion handler is called after the asynchronous part has terminated.
The proactor pattern can be considered to be an asynchronous variant of the synchronous reactor pattern.
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
- The Asynchronous Operation Processor controls the whole asynchronous operation
- The Completion Dispatcher handles the call, depending on the execution environment.
