    • applyTriplePathTransform

      public org.apache.jena.sparql.syntax.Element applyTriplePathTransform(org.apache.jena.sparql.core.TriplePath tp)
      Specified by:
      applyTriplePathTransform in class ElementTransformTripleBasedRewrite
      Parameters:
      tp -
      Returns:
      A substituting element for the argument or null to retain the original TriplePath

    • prefixVarName

      public static String prefixVarName(String prefix, String name)
      Prefix a var name while being aware of special prefixes by the jena system. For example, in the query syntax, a blank node denoted by '[]' is converted into a variable of the form '?0'
      Parameters:
      prefix - The prefix to prepend
      name - The variable name
      Returns:
      A var name with a valid serialization by Jena (if the prefix was valid)

      Parameters:
      t -
      Returns:
      A substituting element for the argument or null to retain the original Triple
