Constants

const OwnerStateKey = `OWNER`

OwnerStateKey key used to store owner grant struct in chain code state

const QueryMethod = `owner`

Variables

var (
	// ErrOwnerNotProvided
	ErrOwnerNotProvided = errors.New(`owner not provided`)

	// ErrOwnerAlreadySetted owner already setted
	ErrOwnerAlreadySetted = errors.New(`owner already setted`)
)

Functions

func Get

func Get(c r.Context) (*identity.Entry, error)

func IdentityEntryFromState

func IdentityEntryFromState(c r.Context) (interface{}, error)

IdentityFromState

func Insert

func Insert(c r.Context, mspID string, cert []byte) (*identity.Entry, error)

Insert

func InvokeSetFromArgs

func InvokeSetFromArgs(c router.Context) (interface{}, error)

InvokeSetFromArgs gets owner data fron args[0] (Msp Id) and arg[1] (cert)

func InvokeSetFromCreator

func InvokeSetFromCreator(c router.Context) (interface{}, error)

InvokeSetFromCreator sets tx creator as chaincode owner, if owner not previously setted

func IsInvoker

func IsInvoker(c r.Context) (bool, error)

IsInvoker checks than tx creator is chain code owner

func IsInvokerOr

func IsInvokerOr(c r.Context, allowedTo ...identity.Identity) (bool, error)

IsInvokerOr checks tx creator and compares with owner of another identity

func IsSetted

func IsSetted(c r.Context) (bool, error)

func Only

func Only(next router.HandlerFunc, pos ...int) router.HandlerFunc

Only allow access from chain code owner

func Query

func Query(c router.Context) (interface{}, error)

FromState returns raw data ( serialized Grant ) of current chain code owner

func SetFromArgs

func SetFromArgs(c r.Context) (*identity.Entry, error)

SetFromArgs set owner fron first args

func SetFromCreator

func SetFromCreator(c r.Context) (*identity.Entry, error)

SetFromCreator sets chain code owner from stub creator
