Constructor & Destructor Documentation

template<typename _Res , typename... _ArgTypes>

std::function< _Res(_ArgTypes...)>::function ( )

inline

Default construct creates an empty function call wrapper.

Postcondition

!(bool)*this

Definition at line 1786 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

std::function< _Res(_ArgTypes...)>::function ( _M_clear_type *  )

inline

Default construct creates an empty function call wrapper.

Postcondition

!(bool)*this

Definition at line 1792 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

std::function< _Res(_ArgTypes...)>::function

(

const function< _Res(_ArgTypes...)> &

__x

)

Function copy constructor.

Parameters

x	A function object with identical call signature.

Precondition

(bool)*this == (bool)x

The newly-created function contains a copy of the target of x (if it has one).

Definition at line 1982 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

template<typename _Functor >

std::function< _Res(_ArgTypes...)>::function	(	_Functor	__f,
		typename __gnu_cxx::__enable_if< !is_integral< _Functor >::value, _Useless >::__type	= _Useless()
	)

Builds a function that targets a copy of the incoming function object.

Parameters

f	A function object that is callable with parameters of type T1, T2, ..., TN and returns a value convertible to Res.

The newly-created function object will target a copy of f. If f is reference_wrapper<F>, then this function object will contain a reference to the function object f.get(). If f is a NULL function pointer or NULL pointer-to-member, the newly-created object will be empty.

If f is a non-NULL function pointer or an object of type reference_wrapper<F>, this function will not throw.

Definition at line 1996 of file tr1_impl/functional.

Member Function Documentation

template<typename _Res , typename... _ArgTypes>

std::function< _Res(_ArgTypes...)>::operator _Safe_bool ( ) const

inline

Determine if the function wrapper has a target.

Returns

true when this function object contains a target, or false when it is empty.

This function will not throw an exception.

Definition at line 1921 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

_Res std::function< _Res(_ArgTypes...)>::operator()

(

_ArgTypes...

__args

)

const

Invokes the function targeted by *this.

Returns

the result of the target.

Exceptions

bad_function_call

when !(bool)*this

The function call operator invokes the target function object stored by this.

Definition at line 2014 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

function& std::function< _Res(_ArgTypes...)>::operator= ( const function< _Res(_ArgTypes...)> &  __x )

inline

Function assignment operator.

Parameters

x	A function with identical call signature.

Postcondition

(bool)*this == (bool)x

Returns

*this

The target of x is copied to *this. If x has no target, then *this will be empty.

If x targets a function pointer or a reference to a function object, then this operation will not throw an exception.

Definition at line 1839 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

function& std::function< _Res(_ArgTypes...)>::operator= ( _M_clear_type *  )

inline

Function assignment to zero.

Postcondition

!(bool)*this

Returns

*this

The target of *this is deallocated, leaving it empty.

Definition at line 1853 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

template<typename _Functor >

__gnu_cxx::__enable_if<!is_integral<_Functor>::value, function&>::__type std::function< _Res(_ArgTypes...)>::operator= ( _Functor  __f )

inline

Function assignment to a new target.

Parameters

f	A function object that is callable with parameters of type T1, T2, ..., TN and returns a value convertible to Res.

Returns

*this

This function object wrapper will target a copy of f. If f is reference_wrapper<F>, then this function object will contain a reference to the function object f.get(). If f is a NULL function pointer or NULL pointer-to-member, this object will be empty.

If f is a non-NULL function pointer or an object of type reference_wrapper<F>, this function will not throw.

Definition at line 1883 of file tr1_impl/functional.

template<typename _Res , typename... _ArgTypes>

void std::function< _Res(_ArgTypes...)>::swap ( function< _Res(_ArgTypes...)> &  __x )

inline

Swap the targets of two function objects.

Parameters

f	A function with identical call signature.

Swap the targets of this function object and f. This function will not throw an exception.
