Functions ¶
func NewTransactionGroup ¶
func NewTransactionGroup(log *transactionLog, current_requestor_id uint64) *transactionGroup
NewTransactionGroup returns a pointer to a new transaction group
func NewTransactionLog ¶
func NewTransactionLog() *transactionLog
NewTransactionLog creats a pointer to transaction log, initializing relevant maps
Types ¶
type Data ¶
Data embeds the datastore's Data and extends it with transaction properties (default values are okay after deserializing).
func (*Data) ExtractGraph ¶
ExtractGraph takes the client's supplied JSON, verifies that it conforms to the schema, and loads it into the LabelGraph data structure
func (*Data) MarshalJSON ¶
type LabelGraph ¶
type LabelGraph struct {
Transactions []transactionItem // transaction ids associated with vertices
Vertices []labelVertex
Edges []labelEdge
}
LabelGraph encodes data exchanged with a client
type Type ¶
Type embeds the datastore's Type to create a unique type for labelgraph functions.
func NewType ¶
func NewType() *Type
NewDatatype returns a pointer to a new keyvalue Datatype with default values set.
func (*Type) NewDataService ¶
func (dtype *Type) NewDataService(uuid dvid.UUID, id dvid.InstanceID, name dvid.InstanceName, c dvid.Config) (datastore.DataService, error)
NewDataService returns a pointer to new keyvalue data with default values.
