Constants

const OwnerStateKey = `OWNER`

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

Variables

Functions

func FromState

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

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

func IdentityEntryFromState

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

IdentityFromState

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 Only

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

Only allow access from chain code owner

func SetFromCreator

func SetFromCreator(c r.Context) peer.Response

SetFromCreator sets chain code owner from stub creator
