Types

type CCPackage

type CCPackage interface {
	//InitFromBuffer initialize the package from bytes
	InitFromBuffer(buf []byte) (*ChaincodeData, error)

	// PutChaincodeToFS writes the chaincode to the filesystem
	PutChaincodeToFS() error

	// GetDepSpec gets the ChaincodeDeploymentSpec from the package
	GetDepSpec() *pb.ChaincodeDeploymentSpec

	// GetDepSpecBytes gets the serialized ChaincodeDeploymentSpec from the package
	GetDepSpecBytes() []byte

	// ValidateCC validates and returns the chaincode deployment spec corresponding to
	// ChaincodeData. The validation is based on the metadata from ChaincodeData
	// One use of this method is to validate the chaincode before launching
	ValidateCC(ccdata *ChaincodeData) error

	// GetPackageObject gets the object as a proto.Message
	GetPackageObject() proto.Message

	// GetChaincodeData gets the ChaincodeData
	GetChaincodeData() *ChaincodeData

	// GetId gets the fingerprint of the chaincode based on package computation
	GetId() []byte
}

CCPackage encapsulates a chaincode package which can be

raw ChaincodeDeploymentSpec
SignedChaincodeDeploymentSpec

Attempt to keep the interface at a level with minimal interface for possible generalization.

type CDSData

type CDSData struct {
	//CodeHash hash of CodePackage from ChaincodeDeploymentSpec
	CodeHash []byte `protobuf:"bytes,1,opt,name=codehash,proto3"`

	//MetaDataHash hash of Name and Version from ChaincodeDeploymentSpec
	MetaDataHash []byte `protobuf:"bytes,2,opt,name=metadatahash,proto3"`
}

CDSData is data stored in the LSCC on instantiation of a CC for CDSPackage. This needs to be serialized for ChaincodeData hence the protobuf format

func (*CDSData) ProtoMessage

func (*CDSData) ProtoMessage()

ProtoMessage just exists to make proto happy

func (*CDSData) Reset

func (data *CDSData) Reset()

Reset resets

func (*CDSData) String

func (data *CDSData) String() string

String converts to string

type ChaincodeData

type ChaincodeData struct {
	// Name of the chaincode
	Name string `protobuf:"bytes,1,opt,name=name"`

	// Version of the chaincode
	Version string `protobuf:"bytes,2,opt,name=version"`

	// Escc for the chaincode instance
	Escc string `protobuf:"bytes,3,opt,name=escc"`

	// Vscc for the chaincode instance
	Vscc string `protobuf:"bytes,4,opt,name=vscc"`

	// Policy endorsement policy for the chaincode instance
	Policy []byte `protobuf:"bytes,5,opt,name=policy,proto3"`

	// Data data specific to the package
	Data []byte `protobuf:"bytes,6,opt,name=data,proto3"`

	// Id of the chaincode that's the unique fingerprint for the CC This is not
	// currently used anywhere but serves as a good eyecatcher
	Id []byte `protobuf:"bytes,7,opt,name=id,proto3"`

	// InstantiationPolicy for the chaincode
	InstantiationPolicy []byte `protobuf:"bytes,8,opt,name=instantiation_policy,proto3"`
}

ChaincodeData defines the datastructure for chaincodes to be serialized by proto Type provides an additional check by directing to use a specific package after instantiation Data is Type specifc (see CDSPackage and SignedCDSPackage)

func (*ChaincodeData) ProtoMessage

func (*ChaincodeData) ProtoMessage()

ProtoMessage just exists to make proto happy

func (*ChaincodeData) Reset

func (cd *ChaincodeData) Reset()

Reset resets

func (*ChaincodeData) String

func (cd *ChaincodeData) String() string

String converts to string
