public static interface Expression.ArithmeticExpression extends Expression
An arithmetic expression is composed of variables, constants, and arithmetic operations; parentheses can be used for ordering operations. The value of the expression can be computed for any given set of variable values (unless a division by zero etc happens).

  • Method Details

    • evalSet

      HashSet<Integer> evalSet(HashMap<String,HashSet<Integer>> h)
      Evaluates this expression for the given values of the variables involved. Can be used when the arguments can have multiple values.
      Parameters:
      h - The hash map that contains for each variable the possible set of its values.
      Returns:
      the set of the possible values of the expression, or an empty set if the expression uses a variable whose value is not in h

    • evalSet2

      HashSet<Object> evalSet2(Expression.VarMap2 h)

    • listAllVars

      HashSet<String> listAllVars()
