  • Method Details

    • determineSatisfiability

      Boolean determineSatisfiability(org.apache.jena.sparql.expr.Expr expr)
      Test whether the given expression is satisfiable in regard to the given restrictions
      Parameters:
      expr - The expression to test for satisfiability
      Returns:
      The assessment of the satisfiability

    • getRestriction

      RestrictionImpl getRestriction(org.apache.jena.sparql.core.Var a)
      Get the restriction associated with the given variable
      Parameters:
      a -
      Returns:

    • getRestriction

      RestrictionImpl getRestriction(org.apache.jena.sparql.expr.Expr expr)
      Return the restriction associated with as expression. If the expression is a variable, getRestriction(Var) is invoked. restriction[concat("a", "b")] = prefixset({"ab"})
      Parameters:
      expr -
      Returns:
