Synopsis

class value_semantic_codecvt_helper<char>
  :  : public boost::program_options::value_semantic
{
public:

  // protected member functions
  virtual void xparse(boost::any &, const std::vector< std::string > &) const;

  // private member functions
  void parse(boost::any &, const std::vector< std::string > &, bool) const;
};

Description

Helper conversion class for values that accept ascii strings as input. Overrides the 'parse' method and defines new 'xparse' method taking std::string. Depending on whether input to parse is ascii or UTF8, will pass it to xparse unmodified, or with UTF8->ascii conversion.

`value_semantic_codecvt_helper` protected member functions

virtual void 
xparse(boost::any & value_store, 
       const std::vector< std::string > & new_tokens) const;

`value_semantic_codecvt_helper` private member functions

```
void parse(boost::any & value_store, 
           const std::vector< std::string > & new_tokens, bool utf8) const;
```
Parses a group of tokens that specify a value of option. Stores the result in 'value_store', using whatever representation is desired. May be be called several times if value of the same option is specified more than once.
