Detailed Description

template<typename Result, typename... Params>
class booster::callback< Result(Params...)>

This is Booster's implementation of std::tr1::callback/booster::callback.

This callback is created from generic object that can be "called" i.e. a class with operator() or callback pointer that has same signature as the callback.

See: http://www.boost.org/doc/html/function.html

Notes:

• this code is not taken from Boost and has slightly different interface.
• as most of compilers do not support Variadic templates yet, this class is explicitly specialized for Params of size 0 to 8. So maximal amout of parameters that can be used is 8.

template<typename Result , typename... Params>

typedef Result booster::callback< Result(Params...)>::result_type

Type of result, for use with boost::bind

---

Constructor & Destructor Documentation

template<typename Result , typename... Params>

booster::callback< Result(Params...)>::callback

(

)

Default constructor, creates an empty callbacks

template<typename Result , typename... Params>

template<typename F >

booster::callback< Result(Params...)>::callback

(

F

func

)

Creates a callback from a callbackal func of type F. func should be copyable. It is copied and stored inside callback object.

template<typename Result , typename... Params>

booster::callback< Result(Params...)>::callback

(

callback< Result(Params...)> const &

other

)

Copy callback, Copies underlying callbackal object.

---

Member Function Documentation

template<typename Result , typename... Params>

bool booster::callback< Result(Params...)>::empty

(

)

const

Return true if the callback is empty

template<typename Result , typename... Params>

booster::callback< Result(Params...)>::operator bool

(

)

const

Returns true if the callback is not empty

template<typename Result , typename... Params>

result_type booster::callback< Result(Params...)>::operator()

(

Params...

params

)

const

Calls underling callbackal object. If the callback is empty, throws bad_callback_call.

template<typename Result , typename... Params>

template<typename F >

callback const& booster::callback< Result(Params...)>::operator=

(

F

func

)

Assign a callbackal func of type F. func should be copyable. It is copied and stored inside callback object.

template<typename Result , typename... Params>

callback const& booster::callback< Result(Params...)>::operator=

(

callback< Result(Params...)> const &

other

)

Assignment operator. Copies underlying callbackal object.

template<typename Result , typename... Params>

void booster::callback< Result(Params...)>::swap

(

callback< Result(Params...)> &

other

)

Swaps two callbackal object. Does not throw.
