Types

type Config

type Config struct {
	// ConnFactory returns a function that creates a connection to an endpoint.
	ConnFactory func(channelID string) func(endpoint string) (*grpc.ClientConn, error)
	// ABCFactory creates an AtomicBroadcastClient out of a connection.
	ABCFactory func(*grpc.ClientConn) orderer.AtomicBroadcastClient
	// CryptoSvc performs cryptographic actions like message verification and signing
	// and identity validation.
	CryptoSvc api.MessageCryptoService
	// Gossip enables to enumerate peers in the channel, send a message to peers,
	// and add a block to the gossip state transfer layer.
	Gossip blocksprovider.GossipServiceAdapter
	// Endpoints specifies the endpoints of the ordering service.
	Endpoints []string
	// Signer is the identity used to sign requests.
	Signer identity.SignerSerializer
}

Config dictates the DeliveryService's properties, namely how it connects to an ordering service endpoint, how it verifies messages received from it, and how it disseminates the messages to other peers

type DeliverService

type DeliverService interface {
	// StartDeliverForChannel dynamically starts delivery of new blocks from ordering service
	// to channel peers.
	// When the delivery finishes, the finalizer func is called
	StartDeliverForChannel(chainID string, ledgerInfo blocksprovider.LedgerInfo, finalizer func()) error

	// StopDeliverForChannel dynamically stops delivery of new blocks from ordering service
	// to channel peers.
	StopDeliverForChannel(chainID string) error

	// UpdateEndpoints
	UpdateEndpoints(chainID string, endpoints []string) error

	// Stop terminates delivery service and closes the connection
	Stop()
}

DeliverService used to communicate with orderers to obtain new blocks and send them to the committer service

func NewDeliverService

func NewDeliverService(conf *Config) (DeliverService, error)

NewDeliverService construction function to create and initialize delivery service instance. It tries to establish connection to the specified in the configuration ordering service, in case it fails to dial to it, return nil
