Struct template throw_

boost::xpressive::op::throw_ — throw_<> is a PolymorphicFunctionObject for throwing an exception.

Synopsis

// In header: <boost/xpressive/regex_actions.hpp>

template<typename Except> 
struct throw_ {
  // types
  typedef void result_type;

  // public member functions
  void operator()() const;
  template<typename A0> void operator()(A0 const &) const;
  template<typename A0, typename A1> 
    void operator()(A0 const &, A1 const &) const;
  template<typename A0, typename A1, typename A2> 
    void operator()(A0 const &, A1 const &, A2 const &) const;
};

Description

Template Parameters

  1. typename Except

    The type of the object to throw.

throw_ public member functions

  1. void operator()() const;

    This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

  2. template<typename A0> void operator()(A0 const & a0) const;

    This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

  3. template<typename A0, typename A1> 
      void operator()(A0 const & a0, A1 const & a1) const;

    This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

  4. template<typename A0, typename A1, typename A2> 
      void operator()(A0 const & a0, A1 const & a1, A2 const & a2) const;

    [Note] Note

    This function makes use of the BOOST_THROW_EXCEPTION macro to actually throw the exception. See the documentation for the Boost.Exception library.

    Parameters:

    a0

    The first argument to the constructor

    a1

    The second argument to the constructor

    a2

    The third argument to the constructor

    Throws:

    <tt>Except(a0
