func ClassifyError added in v1.1.0

func ClassifyError(err error) cb.Status

ClassifyError converts an error type into a status code.


type ChannelSupport added in v1.1.0

type ChannelSupport interface {

ChannelSupport provides the backing resources needed to support broadcast on a channel

type ChannelSupportRegistrar added in v1.1.0

type ChannelSupportRegistrar interface {
	// BroadcastChannelSupport returns the message channel header, whether the message is a config update
	// and the channel resources for a message or an error if the message is not a message which can
	// be processed directly (like CONFIG and ORDERER_TRANSACTION messages)
	BroadcastChannelSupport(msg *cb.Envelope) (*cb.ChannelHeader, bool, ChannelSupport, error)

ChannelSupportRegistrar provides a way for the Handler to look up the Support for a channel

type Consenter added in v1.1.0

type Consenter interface {
	// Order accepts a message or returns an error indicating the cause of failure
	// It ultimately passes through to the consensus.Chain interface
	Order(env *cb.Envelope, configSeq uint64) error

	// Configure accepts a reconfiguration or returns an error indicating the cause of failure
	// It ultimately passes through to the consensus.Chain interface
	Configure(config *cb.Envelope, configSeq uint64) error

	// WaitReady blocks waiting for consenter to be ready for accepting new messages.
	// This is useful when consenter needs to temporarily block ingress messages so
	// that in-flight messages can be consumed. It could return error if consenter is
	// in erroneous states. If this blocking behavior is not desired, consenter could
	// simply return nil.
	WaitReady() error

Consenter provides methods to send messages through consensus

	TxType            string
	Metrics           *Metrics
