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


struct equal_to {
  // types
  typedef bool result_type;

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

  // private static functions
  template<typename T, typename U> 
    static bool op(T const &, U const &, false_type);
  template<typename T, typename U> 
    static bool op(T const &, U const &, true_type);
};

Description

`equal_to` public member functions

template<typename T, typename U> 
  bool operator()(T const & left, U const & right) const;

`equal_to` private static functions

template<typename T, typename U> 
  static bool op(T const & left, U const & right, false_type);

template<typename T, typename U> 
  static bool op(T const & left, U const & right, true_type);
