  Description copied from interface: Expression.ArithmeticExpression
  
  Evaluates this expression for the given values of the variables involved. Can be used when the arguments can have multiple values.
  
  Specified by:
  
  evalSet in interface Expression.ArithmeticExpression
  
  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
  
  public HashSet<Object> evalSet2(Expression.VarMap2 h)
  
  Specified by:
  
  evalSet2 in interface Expression.ArithmeticExpression

- toSrc
  
  public String toSrc()
  
  Specified by:
  
  toSrc in interface Expression
- listAllVars
  
  public HashSet<String> listAllVars()
  
  Specified by:
  
  listAllVars in interface Expression.ArithmeticExpression
- map
  
  public Expression map(Expression.Mapper mapper) throws RuleParseException
  
  Specified by:
  
  map in interface Expression
  
  Throws:
  
  RuleParseException
