Interface RequestProcessor

All Known Implementing Classes:

CommitProcessor, FinalRequestProcessor, FollowerRequestProcessor, LeaderRequestProcessor, ObserverRequestProcessor, PrepRequestProcessor, ProposalRequestProcessor, ReadOnlyRequestProcessor, SendAckRequestProcessor, SyncRequestProcessor, UnimplementedRequestProcessor

public interface RequestProcessor

RequestProcessors are chained together to process transactions. Requests are always processed in order. The standalone server, follower, and leader all have slightly different RequestProcessors chained together. Requests always move forward through the chain of RequestProcessors. Requests are passed to a RequestProcessor through processRequest(). Generally method will always be invoked by a single thread. When shutdown is called, the request RequestProcessor should also shutdown any RequestProcessors that it is connected to.
