Functions

func Drivers

func Drivers() []string

Drivers returns a sorted list of the names of the registered drivers.

func Register

func Register(name string, driver driver.Driver)

Register makes a kvs driver available by the provided name. If Register is called twice with the same name or if driver is nil, it panics.

Types

type ChaincodeEvent

type ChaincodeEvent struct {
	BlockNumber   uint64
	TransactionID string
	ChaincodeID   string
	EventName     string
	Payload       []byte
}

ChaincodeEvent models the chaincode event details.

func (*ChaincodeEvent) Message

func (chaincodeEvent *ChaincodeEvent) Message() interface{}

func (*ChaincodeEvent) Topic

func (chaincodeEvent *ChaincodeEvent) Topic() string

type Committer

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

func New

func New(channel string, network Network, finality Finality, waitForEventTimeout time.Duration, quiet bool, metrics Metrics, publisher events.Publisher) (*Committer, error)

func (*Committer) Commit

func (c *Committer) Commit(block *common.Block) error

Commit commits the transactions in the block passed as argument

func (*Committer) CommitEndorserTransaction

func (c *Committer) CommitEndorserTransaction(txID string, block *common.Block, indexInBlock int, env *common.Envelope, event *TxEvent) error

CommitEndorserTransaction commits the transaction to the vault

func (*Committer) DiscardEndorserTransaction

func (c *Committer) DiscardEndorserTransaction(txID string, block *common.Block, event *TxEvent, validationCode pb.TxValidationCode) error

DiscardEndorserTransaction discards the transaction from the vault

func (*Committer) IsFinal

func (c *Committer) IsFinal(ctx context.Context, txID string) error

IsFinal takes in input a transaction id and waits for its confirmation with the respect to the passed context that can be used to set a deadline for the waiting time.

type ExternalCommitter
