Constructor & Destructor Documentation

template <typename T_return , typename... T_arg>

sigc::slot< T_return(T_arg...)>::slot ( )

inlinedefault

template <typename T_return , typename... T_arg>

template <typename T_functor >

sigc::slot< T_return(T_arg...)>::slot ( const T_functor &  func )

inline

Constructs a slot from an arbitrary functor.

Parameters

func	The desired functor the new slot should be assigned to.

template <typename T_return , typename... T_arg>

sigc::slot< T_return(T_arg...)>::slot ( const slot< T_return(T_arg...)>&  src )

default

Constructs a slot, copying an existing one.

Parameters

src	The existing slot to copy.

template <typename T_return , typename... T_arg>

sigc::slot< T_return(T_arg...)>::slot ( slot< T_return(T_arg...)>&&  src )

inline

Constructs a slot, moving an existing one.

If src is connected to a parent (e.g. a signal), it is copied, not moved.

Parameters

src	The existing slot to move or copy.

Member Function Documentation

template <typename T_return , typename... T_arg>

T_return sigc::slot< T_return(T_arg...)>::operator() ( type_trait_take_t< T_arg >...  a ) const

inline

Invoke the contained functor unless slot is in blocking state.

Parameters

a	Arguments to be passed on to the functor.

Returns

The return value of the functor invocation.

template <typename T_return , typename... T_arg>

slot& sigc::slot< T_return(T_arg...)>::operator= ( const slot< T_return(T_arg...)>&  src )

default

Overrides this slot, making a copy from another slot.

Parameters

src	The slot from which to make a copy.

Returns

this.

template <typename T_return , typename... T_arg>

slot& sigc::slot< T_return(T_arg...)>::operator= ( slot< T_return(T_arg...)>&&  src )

inline

Overrides this slot, making a move from another slot.

If src is connected to a parent (e.g. a signal), it is copied, not moved.

Parameters

src	The slot from which to move or copy.

Returns

this.
