Types

type InstalledChaincode

type InstalledChaincode struct {
	PackageID string
	Hash      []byte
	Label     string
	// References is a map of channel name to chaincode
	// metadata. This represents the channels and chaincode
	// definitions that use this installed chaincode package.
	References map[string][]*Metadata

	// FIXME: we should remove these two
	// fields since they are not properties
	// of the chaincode (FAB-14561)
	Name    string
	Version string
}

InstalledChaincode defines metadata about an installed chaincode

type Metadata

type Metadata struct {
	Name    string
	Version string
	Policy  []byte
	// CollectionPolicies will only be set for _lifecycle
	// chaincodes and stores a map from collection name to
	// that collection's endorsement policy if one exists.
	CollectionPolicies map[string][]byte
	Id                 []byte
	CollectionsConfig  *peer.CollectionConfigPackage
	// These two fields (Approved, Installed) are only set for
	// _lifecycle chaincodes. They are used to ensure service
	// discovery doesn't publish a stale chaincode definition
	// when the _lifecycle definition exists but has not yet
	// been installed or approved by the peer's org.
	Approved  bool
	Installed bool
}

Metadata defines channel-scoped metadata of a chaincode

type MetadataMapping

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

MetadataMapping defines a mapping from chaincode name to Metadata

func NewMetadataMapping

func NewMetadataMapping() *MetadataMapping

NewMetadataMapping creates a new metadata mapping

func (*MetadataMapping) Aggregate

func (m *MetadataMapping) Aggregate() MetadataSet

Aggregate aggregates all Metadata to a MetadataSet

func (*MetadataMapping) Lookup

func (m *MetadataMapping) Lookup(cc string) (Metadata, bool)

Lookup returns the Metadata that is associated with the given chaincode

func (*MetadataMapping) Update

func (m *MetadataMapping) Update(ccMd Metadata)

Update updates the chaincode metadata in the mapping

type MetadataSet

type MetadataSet []Metadata

MetadataSet defines an aggregation of Metadata

func (MetadataSet) AsChaincodes

func (ccs MetadataSet) AsChaincodes() []*gossip.Chaincode

AsChaincodes converts this MetadataSet to a slice of gossip.Chaincodes
