func (DataType) NativeType 

func (d DataType) NativeType(value string) (any, bool, error)

NativeType returns the native type of the given value. Returns true if the value was converted, otherwise false.

func (DataType) Validate 

func (d DataType) Validate(v any, acceptString bool) bool

Validate returns true if the given value is valid for the datatype.

type Graph 

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

func NewGraph 

func NewGraph(ts ...*Triple) *Graph

func (*Graph) Add 

func (g *Graph) Add(s, p, o Node)

func (*Graph) Find 

func (g *Graph) Find(s, p, o Node) *Triple

Find returns the first triple matching the given pattern.

func (*Graph) FindAll 

func (g *Graph) FindAll(s, p, o Node) []*Triple

FindAll returns all triples matching the given pattern.

func (*Graph) Remove
