Struct template throw

Struct template throw_

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

Synopsis

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

template<typename Except> 
struct throw_ {

  // 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

```
typename Except
```
The type of the object to throw.

`throw_` public member functions

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

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