func (*DaughterTrustIteratorProvider) InitConsumersIterator

func (ip *DaughterTrustIteratorProvider) InitConsumersIterator(
	ctx eigentrustcalc.Context) (eigentrustcalc.PeerTrustsIterator, error)

InitConsumersIterator returns iterator over all daughters of the current node(manager) and all their consumers' local trusts for ctx.Epoch() epoch and ctx.I() iteration.

Returns ErrNoData if there is no trust data for specified epoch and iteration.

func (*DaughterTrustIteratorProvider) InitDaughterIterator

func (ip *DaughterTrustIteratorProvider) InitDaughterIterator(ctx eigentrustcalc.Context,
	p reputation.PeerID) (eigentrustcalc.TrustIterator, error)

InitDaughterIterator returns iterator over received local trusts for ctx.Epoch() epoch from daughter p.

Returns ErrNoData if there is no trust data for specified epoch and daughter's PeerId.

type DaughterTrustWriter

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

DaughterTrustWriter is implementation of reputation.Writer interface that writes passed daughter's Trust values to Daughter storage. After writing that values can be used in eigenTrust algorithm's iterations.

func (*DaughterTrustWriter) Close

func (w *DaughterTrustWriter) Close() error

func (*DaughterTrustWriter) Write

func (w *DaughterTrustWriter) Write(t reputation.Trust) error

type DaughtersTrustCalculator

type DaughtersTrustCalculator struct {
	Calculator *eigencalc.Calculator
}

DaughtersTrustCalculator wraps EigenTrust calculator and implements eigentrust/calculator's DaughtersTrustCalculator interface.

func (*DaughtersTrustCalculator) Calculate

func (c *DaughtersTrustCalculator) Calculate(ctx eigentrustctrl.IterationContext)

Calculate converts and passes values to wrapped calculator.

type ErrNoData

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

func (*ErrNoData) Error

func (e *ErrNoData) Error() string

type FinalWriter

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

FinalWriter is implementation of reputation.eigentrust.calculator IntermediateWriter interface that writes GlobalTrust to contract directly.

func (FinalWriter) WriteIntermediateTrust

func (fw FinalWriter) WriteIntermediateTrust(t eigentrust.IterationTrust) error

type FinalWriterOption

type FinalWriterOption func(*finalWriterOptions)

func FinalWriterWithLogger

func FinalWriterWithLogger(l *logger.Logger) FinalWriterOption

type FinalWriterProvider

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

FinalWriterProvider is implementation of reputation.eigentrust.calculator IntermediateWriterProvider interface. It inits FinalWriter.

func NewFinalWriterProvider

func NewFinalWriterProvider(prm FinalWriterProviderPrm, opts ...FinalWriterOption) *FinalWriterProvider

NewFinalWriterProvider creates a new instance of the FinalWriterProvider.

Panics if at least one value of the parameters is invalid.

The created FinalWriterProvider does not require additional initialization and is completely ready for work.
