func (HandleMetadataUpdateFunc) HandleMetadataUpdate added in v1.5.6

func (handleMetadataUpdate HandleMetadataUpdateFunc) HandleMetadataUpdate(channel string, chaincodes chaincode.MetadataSet)

HandleMetadataUpdate runs whenever there is a change to the metadata of a chaincode in the context of a specific channel

type MetadataChangeListener added in v1.5.6

type MetadataChangeListener interface {
	HandleMetadataUpdate(channel string, chaincodes chaincode.MetadataSet)
}

MetadataChangeListener runs whenever there is a change to the metadata of a chaincode in the context of a specific channel

type MetadataManager added in v1.5.6

type MetadataManager struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

MetadataManager manages information about lscc chaincodes.

func NewMetadataManager added in v1.5.6

func NewMetadataManager(installedChaincodes Enumerator) (*MetadataManager, error)

NewMetadataManager creates a metadata manager for lscc chaincodes.

func (*MetadataManager) AddListener added in v1.5.6

func (m *MetadataManager) AddListener(listener MetadataChangeListener)

AddListener registers the given listener to be triggered upon a lifecycle change

func (*MetadataManager) Metadata added in v1.5.6

func (m *MetadataManager) Metadata(channel string, cc string, collections ...string) *chaincode.Metadata

Metadata returns the metadata of the chaincode on the given channel, or nil if not found or an error occurred at retrieving it

func (*MetadataManager) NewChannelSubscription added in v1.5.6

func (m *MetadataManager) NewChannelSubscription(channel string, queryCreator QueryCreator) (*Subscription, error)

NewChannelSubscription subscribes to a channel

type Query

type Query interface {
	// GetState gets the value for given namespace and key. For a chaincode, the namespace corresponds to the chaincodeId
	GetState(namespace string, key string) ([]byte, error)

	// Done releases resources occupied by the QueryExecutor
	Done()
}

Query queries the state

type QueryCreator

type QueryCreator interface {
	// NewQuery creates a new Query, or error on failure
	NewQuery() (Query, error)
}

QueryCreator creates queries

type QueryCreatorFunc

type QueryCreatorFunc func() (Query, error)

QueryCreatorFunc creates a new query

func (QueryCreatorFunc) NewQuery

func (queryCreator QueryCreatorFunc) NewQuery() (Query, error)

NewQuery creates a new Query, or error on failure

type Subscription

type Subscription struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Subscription channels information flow about a specific channel into the Lifecycle.

func (*Subscription) ChaincodeDeployDone

func (sub *Subscription) ChaincodeDeployDone(succeeded bool)

ChaincodeDeployDone gets invoked when the chaincode deploy transaction or chaincode install (the context in which the above function was invoked).

func (*Subscription) HandleChaincodeDeploy

func (sub *Subscription) HandleChaincodeDeploy(chaincodeDefinition *cceventmgmt.ChaincodeDefinition, dbArtifactsTar []byte) error

HandleChaincodeDeploy is expected to be invoked when a chaincode is deployed via a deploy transaction and the chaincode was already installed on the peer. This also gets invoked when an already deployed chaincode is installed on the peer.
