Synopsis

// In header: <boost/unicode/hangul.hpp>


struct hangul_composer {
  // types
  typedef char32         input_type; 
  typedef char32         output_type;
  typedef mpl::int_< 1 > max_output; 

  // public member functions
  template<typename In, typename Out> std::pair< In, Out > ltr(In, In, Out) ;
  template<typename In, typename Out> std::pair< In, Out > rtl(In, In, Out) ;

  // private static functions
  static bool is_l(char32) ;
  static bool is_v(char32) ;
  static char32 combine_l_v(char32, char32) ;
  static bool is_lv(char32) ;
  static bool is_t(char32) ;
  static char32 combine_lv_t(char32, char32) ;
};

Description

Pipe that transforms <L, V>, <L, V, T> and <LV, T> Hangul code points sequences into the LV and LVT Hangul syllables, since those compositions are not part of the UCD. Other code points are left unchanged.
