boost::log::in_range_fun — The in_range functor.

Synopsis

// In header: <boost/log/utility/functional/in_range.hpp>


struct in_range_fun {
  // types
  typedef bool result_type;

  // public member functions
  template<typename T, typename U> 
    bool operator()(T const &, std::pair< U, U > const &) const;

  // private static functions
  template<typename T, typename U> 
    static bool op(T const &, std::pair< U, U > const &, mpl::false_ const &);
  template<typename T, typename U> 
    static bool op(T const &, std::pair< U, U > const &, mpl::true_ const &);
};
