Functions

func RegisterChaincodeProviderFactory

func RegisterChaincodeProviderFactory(ccfact ChaincodeProviderFactory)

RegisterChaincodeProviderFactory is to be called once to set the factory that will be used to obtain instances of ChaincodeProvider

Types

type CCContext

type CCContext struct {
	//ChainID chain id
	ChainID string

	//Name chaincode name
	Name string

	//Version used to construct the chaincode image and register
	Version string

	//TxID is the transaction id for the proposal (if any)
	TxID string

	//Syscc is this a system chaincode
	Syscc bool

	//Proposal for this invoke (if any)
	//this is kept here just in case we need to pass something
	//from this to the chaincode
	Proposal *pb.Proposal
	// contains filtered or unexported fields
}

CCContext pass this around instead of string of args

func NewCCContext

func NewCCContext(cid, name, version, txid string, syscc bool, prop *pb.Proposal) *CCContext

NewCCContext just construct a new struct with whatever args

func (*CCContext) GetCanonicalName

func (cccid *CCContext) GetCanonicalName() string

GetCanonicalName returns the canonical name associated with the proposal context

type ChaincodeData

type ChaincodeData struct {
	Name    string `protobuf:"bytes,1,opt,name=name"`
	Version string `protobuf:"bytes,2,opt,name=version"`
	DepSpec []byte `protobuf:"bytes,3,opt,name=depSpec,proto3"`
	Escc    string `protobuf:"bytes,4,opt,name=escc"`
	Vscc    string `protobuf:"bytes,5,opt,name=vscc"`
	Policy  []byte `protobuf:"bytes,6,opt,name=policy"`
}

ChaincodeData defines the datastructure for chaincodes to be serialized by proto

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 convers to string

type ChaincodeProvider

type ChaincodeProvider interface {
	// GetContext returns a ledger context
	GetContext(ledger ledger.PeerLedger) (context.Context, error)
	// GetCCContext returns an opaque chaincode context
	GetCCContext(cid, name, version, txid string, syscc bool, prop *pb.Proposal) interface{}
	// GetCCValidationInfoFromLCCC returns the VSCC and the policy listed by LCCC for the supplied chaincode
	GetCCValidationInfoFromLCCC(ctxt context.Context, txid string, prop *pb.Proposal, chainID string, chaincodeID string) (string, []byte, error)
	// ExecuteChaincode executes the chaincode given context and args
	ExecuteChaincode(ctxt context.Context, cccid interface{}, args [][]byte) (*pb.Response, *pb.ChaincodeEvent, error)
	// Execute executes the chaincode given context and spec (invocation or deploy)
	Execute(ctxt context.Context, cccid interface{}, spec interface{}) (*pb.Response, *pb.ChaincodeEvent, error)
	// ExecuteWithErrorFilder executes the chaincode given context and spec and returns payload
	ExecuteWithErrorFilter(ctxt context.Context, cccid interface{}, spec interface{}) ([]byte, *pb.ChaincodeEvent, error)
	// Stop stops the chaincode given context and deployment spec
	Stop(ctxt context.Context, cccid interface{}, spec *pb.ChaincodeDeploymentSpec) error
	// ReleaseContext releases the context returned previously by GetContext
	ReleaseContext()
}

ChaincodeProvider provides an abstraction layer that is used for different packages to interact with code in the chaincode package without importing it; more methods should be added below if necessary

func GetChaincodeProvider

func GetChaincodeProvider() ChaincodeProvider

GetChaincodeProvider returns instances of ChaincodeProvider; the actual implementation is controlled by the factory that is registered via RegisterChaincodeProviderFactory

type ChaincodeProviderFactory

type ChaincodeProviderFactory interface {
	NewChaincodeProvider() ChaincodeProvider
}

ChaincodeProviderFactory defines a factory interface so that the actual implementation can be injected
