Not to be confused with the last change in the store, which might be later than the flush time.

typeCache

typeCache: NamedNode[][] = []

Accessors

rdfFactory

  • get rdfFactory(): DataFactory
  • set rdfFactory(_: DataFactory): void

    Returns Quad[]

queueDelta

removeQuads

  • removeQuads(statements: Quad[]): void

removeResource

  • removeResource(subject: SomeNode): void

replaceMatches

  • replaceMatches(statements: Quadruple[]): Quad[]

replaceQuads

  • replaceQuads(original: Quad[], replacements: Quad[]): Quad[]

  • Removes an array of statements and inserts another. Note: Be sure that the replacement contains the same subjects as the original to let the broadcast work correctly.

    access

    private This is in conflict with the typescript declaration due to the development of some experimental features, but this method shouldn't be used nevertheless.

    Parameters

    • original: Quad[]

      The statements to remove from the store.

    • replacements: Quad[]

      The statements to add to the store.

    Returns Quad[]
