Struct template function_reference_wrapper

boost::log::function_reference_wrapper — Reference wrapper for function objects.


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

template<typename FunT> 
struct function_reference_wrapper {
  // types
  typedef FunT::result_type result_type;

  // construct/copy/destruct
  explicit function_reference_wrapper(FunT &);

  // public member functions
  result_type operator()() const;
  template<typename... ArgsT> result_type operator()(ArgsT const &...) const;


function_reference_wrapper public construct/copy/destruct

  1. explicit function_reference_wrapper(FunT & fun);

function_reference_wrapper public member functions

  1. result_type operator()() const;
  2. template<typename... ArgsT> 
      result_type operator()(ArgsT const &... args) const;
