type Collection ¶

type Collection interface {
	Iterator() Iterator
	First() Step
	Size() uint64
	AsSlice() []Step
	SourceGraph() Graph
}

type Graph ¶

type Graph interface {
	ROGraph
	Concept(Step) Step
	Assert(Step, Step, v.Value) Step
}

type Identifier ¶

type Identifier = v.Identifier

type Iterator ¶

type Iterator interface {
	Next() bool
	Value() Step
}

An Iterator allows iterating over query results, like this: `it := graph.Query(...).Iterator()

for it.Next() { s := it.Value(); ... }`

func SliceIterator(data []Step) Iterator

type ROGraph ¶

type ROGraph interface {
	Content() Collection
	Last() Step
	Size() uint64
	Query(Step, Step, v.Value) Collection
	Get(string, Step) Step
	Ref(Step) string
	Concepts() Collection
}

type Step ¶

type Step interface {
	StepCore
	v.Value
}

interface Step, type step: a semantic (RDF-like) triple, representing a statment of the form <subject>, <predicate>, <object>.

func MakeStep(cs StepCore) Step

type StepCore ¶ added in v0.1.12

type StepCore interface {
	Item() Step
	Property() Step
	Value() v.Value
	Id() Identifier
	Graph() Graph
}
