      public boolean shouldOutputId()
      Overrides:
      shouldOutputId in class RDFNode
      Returns:
      true if blank node id is mandatory for this resource

    • setIdRequired

      public void setIdRequired(boolean b)
      Parameters:
      b - change the value of the id required flag

    • isLiteral
