  • Method Details

    • isBNode

      default boolean isBNode()
      Check if the object is an instance of the given type. Typically 2x than using instanceof. For implementers: This default implementation is overridden in the repsective sub-interface.
      Returns:
      true if instance of BNode

    • isIRI

      default boolean isIRI()
      Check if the object is an instance of the given type. Typically 2x than using instanceof. For implementers: This default implementation is overridden in the repsective sub-interface.
      Returns:
      true if instance of IRI

    • isResource

      default boolean isResource()
      Check if the object is an instance of the given type. Typically 2x than using instanceof. For implementers: This default implementation is overridden in the repsective sub-interface.
      Returns:
      true if instance of Resource

    • isLiteral

      default boolean isLiteral()
      Check if the object is an instance of the given type. Typically 2x than using instanceof. For implementers: This default implementation is overridden in the repsective sub-interface.
      Returns:
      true if instance of Literal

    • isTriple

      default boolean isTriple()
      Check if the object is an instance of the given type. Typically 2x than using instanceof. For implementers: This default implementation is overridden in the repsective sub-interface.
      Returns:
      true if instance of Triple

    • stringValue

      String stringValue()
      Returns the String-value of a Value object. This returns either a Literal's label, a IRI's URI or a BNode's ID.
