Class Statement<S, P, O, G>

constructor

• new Statement<
      S extends SubjectType = SubjectType,
      P extends PredicateType = PredicateType,
      O extends ObjectType = ObjectType,
      G extends GraphType = GraphType,
  >(
      subject: S,
      predicate: P,
      object: O,
      graph?: DefaultGraph | G,
  ): Statement<S, P, O, G>

  Construct a new statement

  Type Parameters

  • S extends SubjectType = SubjectType
  • P extends PredicateType = PredicateType
  • O extends ObjectType = ObjectType
  • G extends GraphType = GraphType

  Parameters

  • subject: S

    The subject of the triple. What the fact is about
  • predicate: P

    The relationship which is asserted between the subject and object
  • object: O

    The thing or data value which is asserted to be related to the subject
  • Optionalgraph: DefaultGraph | G

    The document where the triple is or was or will be stored on the web.

    The graph param is a named node of the document in which the triple when it is stored on the web. It exists because when you have read data from various places in the web, the “graph” tells you why you have the triple. (At the moment, it is just the document, in future it could be an inference step)

    When you do UpdateManager.update() then the graph’s of all the statements must be the same, and give the document you are patching. In future, we may have a more powerful update() which can update more than one document.

  Returns Statement<S, P, O, G>
