Types

type Graph

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

Graph serves as a buffer that consumes triples one by one and can return a byte slice containing Turtle data of all triples consumed.

func New

func New() *Graph

New returns a pointer to a new instance of graph.Graph. No options are set.

func NewWithOptions

func NewWithOptions(options Options) *Graph

NewWithOptions constructs a graph with options to tweak its behavior. See Options.

func (*Graph) Accept

func (g *Graph) Accept(t [3]string) error

Accept stores a new triple to the graph.

func (*Graph) AcceptWithAnnotations

func (g *Graph) AcceptWithAnnotations(t [6]string) error

AcceptWithAnnotations stores a new triple with eventual label and data type of the object literal to the graph.

func (*Graph) Bytes

func (g *Graph) Bytes() ([]byte, error)

Bytes returns the so far consumed triples as a byte slice of Turle data. The triples in the byte slice are sorted first by subject, then by predicates, then by objects alphabetically.

type Options

type Options struct {
	// If set, will output a `@base` pragma at the start. Will normalize all URLs
	// that start with the base to their relative components.
	Base string
	// If set, any encountering of the prefix URL prefixes will be normalized to
	// use the prefix. Additionally, @prefix lines are output at the top of the
	// document for each one.
	Prefixes map[string]string
}

Options changes the behavior of the graph. It is passed to NewWithOptions.
