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

    Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed. This allows proper clean up of stray promises when the node is transitioning to a passive state.

    Note: you should *not* invoke success on the returned promise but rather use trySuccess. The reason is that the call to success may fail in case of shutdown.
