abstract class ProtocolProcessor[SubmissionParam, SubmissionResult, RequestViewType <: ViewType, SubmissionError <: WrapsProcessorError] extends AbstractMessageProcessor with RequestProcessor[RequestViewType]
The ProtocolProcessor orchestrates Phase 3, 4, and 7 of the synchronization protocol. For this, it combines ProcessingSteps specific to a particular kind of request (transaction / reassignment) with the common processing steps.
- SubmissionParam
The bundled submission parameters
- SubmissionResult
The bundled submission results
- RequestViewType
The type of view trees used by the request
- SubmissionError
The type of errors that occur during submission processing
