tuple

func BuildObject ¶

func BuildObject(objectType, objectID string) string

func GetRelation ¶

func GetRelation(objectRelation string) string

GetRelation returns the 'relation' portion of an object relation string, which may be empty if the input is malformed (or does not contain a relation specifier).

func GetType ¶

func GetType(objectID string) string

GetType returns the type from a supplied Object identifier or an empty string if the object id does not contain a type.

func IsObjectRelation ¶

func IsObjectRelation(userset string) bool

IsObjectRelation returns true if the given string specifies a valid object and relation.

func IsType ¶

func IsType(object string) bool

IsType returns true if the given string contains just a type.

func IsValidObject ¶

func IsValidObject(s string) bool

IsValidObject determines if a string s is a valid object. A valid object contains exactly one `:` and no `#` or spaces.

func IsValidRelation ¶

func IsValidRelation(s string) bool

IsValidRelation determines if a string s is a valid relation. This means it does not contain any `:`, `#`, or spaces.

func IsValidUser ¶

func IsValidUser(user string) bool

IsValidUser determines if a string s is a valid user. A valid user contains at most one `:` and no `#` or spaces.

func NewTupleKey ¶

func NewTupleKey(object, relation, user string) *openfgapb.TupleKey

func SplitObject ¶

func SplitObject(object string) (string, string)

SplitObject splits an object into an objectType and an objectID. If no type is present, it returns the empty string and the original object.

func SplitObjectRelation ¶

func SplitObjectRelation(objectRelation string) (string, string)

SplitObjectRelation splits an object relation string into an object ID and relation name. If no relation is present, it returns the original string and an empty relation.

func ToObjectRelationString ¶

func ToObjectRelationString(object, relation string) string

ToObjectRelationString formats an object/relation pair as an object#relation string. This is the inverse of SplitObjectRelation.

func TupleKeyToString ¶

func TupleKeyToString(tk *openfgapb.TupleKey) string

TupleKeyToString converts a tuple key into its string representation. It assumes the tupleKey is valid (i.e. no forbidden characters)

func ValidateObjectsRelations ¶

func ValidateObjectsRelations(ctx context.Context, backend storage.TypeDefinitionReadBackend, store, modelID string, t *openfgapb.TupleKey, dbCallsCounter utils.DBCallCounter) (*openfgapb.Userset, error)

ValidateObjectsRelations returns whether a tuple's object and relations are valid

func ValidateTuple ¶

func ValidateTuple(ctx context.Context, backend storage.TypeDefinitionReadBackend, store, authorizationModelID string, tk *openfgapb.TupleKey, dbCallsCounter utils.DBCallCounter) (*openfgapb.Userset, error)

ValidateTuple returns whether a *openfgapb.TupleKey is valid
