  • Method Details

    • visitDefault

      protected abstract R visitDefault(Formula f)
      Method for default case, is called by all methods from this class if they are not overridden.
      Parameters:
      f - Formula for the currently visited node.
      Returns:
      An arbitrary value, will be passed through to the caller.

    • visitFreeVariable

      public R visitFreeVariable(Formula f, String name)
      Description copied from interface: FormulaVisitor
      Visit a free variable (such as "x", "y" or "z"), not bound by a quantifier. The variable can have any sort (both boolean and non-boolean).
      Specified by:
      visitFreeVariable in interface FormulaVisitor<R>
      Parameters:
      f - Formula representing the variable.
      name - Variable name.

    • visitBoundVariable

      public R visitBoundVariable(Formula f, int deBruijnIdx)
      Description copied from interface: FormulaVisitor
      Visit a variable bound by a quantifier. The variable can have any sort (both boolean and non-boolean).
      Specified by:
      visitBoundVariable in interface FormulaVisitor<R>
      Parameters:
      f - Formula representing the variable.
      deBruijnIdx - de-Bruijn index of the bound variable, which can be used to find the matching quantifier.

    • visitConstant

      public R visitConstant(Formula f, Object value)
      Description copied from interface: FormulaVisitor
      Visit a constant, such as "true"/"false", a numeric constant like "1" or "1.0", a String constant like 2hello world" or enumeration constant like "Blue".
      Specified by:
      visitConstant in interface FormulaVisitor<R>
      Parameters:
      f - Formula representing the constant.
      value - The value of the constant. It is either of type Boolean, of a subtype of Number (mostly a BigInteger, a BigDecimal, or a Rational), or String.
      Returns:
      An arbitrary return value that is passed to the caller.

    • visitFunction

      public R visitFunction(Formula f, List<Formula> args, FunctionDeclaration<?> functionDeclaration)
      Description copied from interface: FormulaVisitor
      Visit an arbitrary, potentially uninterpreted function. The function can have any sort.
      Specified by:
      visitFunction in interface FormulaVisitor<R>
      Parameters:
      f - Input function.
      args - List of arguments
      functionDeclaration - Function declaration. Can be given to FormulaManager.makeApplication(org.sosy_lab.java_smt.api.FunctionDeclaration<T>, java.util.List<? extends org.sosy_lab.java_smt.api.Formula>) to construct a new instance of the same function with different arguments.

    • visitQuantifier

      public R visitQuantifier(BooleanFormula f, QuantifiedFormulaManager.Quantifier q, List<Formula> boundVariables, BooleanFormula body)
      Description copied from interface: FormulaVisitor
      Visit a quantified node.
      Specified by:
      visitQuantifier in interface FormulaVisitor<R>
      Parameters:
      f - Quantifier formula.
      q - Quantifier type: either FORALL or EXISTS.
      boundVariables - Variables bound by the quantifier. NOTE: not all solvers hold metadata about bound variables. In case this is not available, this method will be called with an empty list, yet #mkQuantifier will work fine with an empty list as well.
      body - Body of the quantifier.
