Types ¶
type ChaincodeStore ¶
type ChaincodeStore interface {
Save(name, version string, ccInstallPkg []byte) (hash []byte, err error)
RetrieveHash(name, version string) (hash []byte, err error)
}
ChaincodeStore provides a way to persist chaincodes
type Lifecycle ¶
type Lifecycle struct {
ChaincodeStore ChaincodeStore
PackageParser PackageParser
}
Lifecycle implements the lifecycle operations which are invoked by the SCC as well as internally
type PackageParser ¶
type PackageParser interface {
Parse(data []byte) (*persistence.ChaincodePackage, error)
}
type Protobuf ¶ added in v1.4.0
type Protobuf interface {
Marshal(msg proto.Message) (marshaled []byte, err error)
Unmarshal(marshaled []byte, msg proto.Message) error
}
Protobuf defines the subset of protobuf lifecycle needs and allows for injection of mocked marshaling errors.
type ProtobufImpl ¶ added in v1.4.0
type ProtobufImpl struct{}
ProtobufImpl is the standard implementation to use for Protobuf
type SCC ¶
type SCC struct {
Protobuf Protobuf
Functions SCCFunctions
}
SCC implements the required methods to satisfy the chaincode interface. It routes the invocation calls to the backing implementations.
func (*SCC) Init ¶
func (scc *SCC) Init(stub shim.ChaincodeStubInterface) pb.Response
Init is mostly useless for system chaincodes and always returns success
func (*SCC) InvokableExternal ¶
InvokableExternal returns true
func (*SCC) Invoke ¶
func (scc *SCC) Invoke(stub shim.ChaincodeStubInterface) pb.Response
Invoke takes chaincode invocation arguments and routes them to the correct underlying lifecycle operation. All functions take a single argument of type marshaled lb.<FunctionName>Args and return a marshaled lb.<FunctionName>Result
type SCCFunctions ¶ added in v1.4.0
type SCCFunctions interface {
// InstallChaincode persists a chaincode definition to disk
InstallChaincode(name, version string, chaincodePackage []byte) (hash []byte, err error)
// QueryInstalledChaincode returns the hash for a given name and version of an installed chaincode
QueryInstalledChaincode(name, version string) (hash []byte, err error)
}
SCCFunctions provides a backing implementation with concrete arguments for each of the SCC functions
