Types

type Log

type Log struct {
	// contains filtered or unexported fields
}

func ConstructLog

func ConstructLog(roleId uint64, disk *recovery.Manager) (*Log, error)

Creates a new replicated log instance, using data from cold storage files

func (*Log) GetEntryAt

func (this *Log) GetEntryAt(index int) LogEntry

Returns details of the log entry at the specified index

func (*Log) GetFirstUnchosenIndex

Returns the index of the first entry in the log for which no value has been chosen

func (*Log) GetMinProposalId

func (this *Log) GetMinProposalId() proposal.Id

Returns the minimum proposal for this log; all lesser proposals should be rejected

func (*Log) MarkAsChosen

func (this *Log) MarkAsChosen(proposalId proposal.Id, upto int)

Marks all log entries with the given proposalId as chosen, up to the given index

func (*Log) NoMoreAcceptedPast
