Class error_with_no_option_name

boost::program_options::error_with_no_option_name

Synopsis

// In header: <boost/program_options/errors.hpp>


class error_with_no_option_name :
  public boost::program_options::error_with_option_name
{
public:

  // public member functions
  error_with_no_option_name(const std::string &, const std::string & = "");
  virtual void set_option_name(const std::string &);
};

Description

Base class of unparsable options, when the desired option cannot be identified.

It makes no sense to have an option name, when we can't match an option to the parameter

Having this a part of the error_with_option_name hierachy makes error handling a lot easier, even if the name indicates some sort of conceptual dissonance!

`error_with_no_option_name` public member functions

error_with_no_option_name(const std::string & template_, 
                          const std::string & original_token = "");

```
virtual void set_option_name(const std::string &);
```
Does NOT set option name, because no option name makes sense
