Types

type Graph

type Graph []*rdfpb.Triple

Graph represents a set of RDF Triples.

func (*Graph) Add

func (g *Graph) Add(t *rdfpb.Triple) *Graph

Add the given RDF Triple to the graph.

func (Graph) MarshalBinary

func (g Graph) MarshalBinary() ([]byte, error)

MarshalBinary implements the encoding.BinaryMarshaler interface.

Binary format = repeat 8 bytes + n bytes 8 bytes = length of RDF Triple protobuf message n bytes = RDF Triple protobuf message

func (Graph) MarshalJSON

func (g Graph) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler interface.

CAUTION!! Always prefer MarshalBinary over this. This relies in protojson which does not define a stable version.

func (Graph) Triples

func (g Graph) Triples() []*rdfpb.Triple

Triples returns all the returns contained within the graph.

func (*Graph) UnmarshalBinary

func (g *Graph) UnmarshalBinary(data []byte) error

UnmarshalBinary implements the encoding.BinaryUnmarshaler interface.

Binary format = repeat 8 bytes + n bytes 8 bytes = length of RDF Triple protobuf message n bytes = RDF Triple protobuf message

func (*Graph) UnmarshalJSON

func (g *Graph) UnmarshalJSON(data []byte) error

UnmarshalJSON implements json.Unmarshaler interface.

CAUTION!! Always prefer UnmarshalBinary over this. This relies in protojson which does not define a stable version.

type Predicate

type Predicate string
