Detailed Description

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

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

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

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.

Member Typedef Documentation

template<typename Result , typename... Params>

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

Type of result, for use with boost::bind

Constructor & Destructor Documentation

template<typename Result , typename... Params>

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

(

)

Default constructor, creates an empty functions

template<typename Result , typename... Params>

template<typename F >

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

(

F

func

)

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

template<typename Result , typename... Params>

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

(

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

other

)

Copy function, Copies underlying functional object.

Member Function Documentation

template<typename Result , typename... Params>

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

(

)

const

Return true if the function is empty

template<typename Result , typename... Params>

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

(

)

const

Returns true if the function is not empty

template<typename Result , typename... Params>

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

(

Params...

params

)

const

Calls underling functional object. If the function is empty, throws bad_function_call.

template<typename Result , typename... Params>

template<typename F >

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

(

F

func

)

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

template<typename Result , typename... Params>

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

(

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

other

)

Assignment operator. Copies underlying functional object.

template<typename Result , typename... Params>

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

(

function< Result(Params...)> &

other

)

Swaps two functional object. Does not throw.
