Types

type ConditionalResultStatus

type ConditionalResultStatus int

const (
	RequiresFurtherEvalStatus ConditionalResultStatus = iota
	NoFurtherEvalStatus
)

type IsUserRef

type IsUserRef interface {
	GetObjectType() string
	String() string
	// contains filtered or unexported methods
}

type ResolutionMetadata

type ResolutionMetadata struct {
	DatastoreQueryCount *uint32

	// The number of times we are expanding from each node to find set of objects
	DispatchCount *uint32
}

func NewResolutionMetadata

func NewResolutionMetadata() *ResolutionMetadata

type ReverseExpandQuery

type ReverseExpandQuery struct {
	// contains filtered or unexported fields
}

func NewReverseExpandQuery

func NewReverseExpandQuery(ds storage.RelationshipTupleReader, ts *typesystem.TypeSystem, opts ...ReverseExpandQueryOption) *ReverseExpandQuery

func (*ReverseExpandQuery) Execute

func (c *ReverseExpandQuery) Execute(
	ctx context.Context,
	req *ReverseExpandRequest,
	resultChan chan<- *ReverseExpandResult,
	resolutionMetadata *ResolutionMetadata,
) error

Execute yields all the objects of the provided objectType that the given user possibly has, a specific relation with and sends those objects to resultChan. It MUST guarantee no duplicate objects sent.

This function respects context timeouts and cancellations. If an error is encountered (e.g. context timeout) before resolving all objects, then the provided channel will NOT be closed, and it will return the error.

If no errors occur, then Execute will yield all of the objects on the provided channel and then close the channel to signal that it is done.
