Detailed Description

template <class T_return, class T_arg1, class T_accumulator>
struct sigc::internal::signal_emit1< T_return, T_arg1, T_accumulator >

Abstracts signal emission.

This template implements the emit() function of signal1. Template specializations are available to optimize signal emission when no accumulator is used, i.e. the template argument T_accumulator is nil.

Constructor & Destructor Documentation

template <class T_return, class T_arg1, class T_accumulator>
sigc::internal::signal_emit1<T_return, T_arg1, T_accumulator>::signal_emit1 ( typename type_trait<T_arg1>::take  _A_a1  )  [inline]
 

Instantiates the class.

The parameters are stored in member variables. operator()() passes the values on to some slot.


Member Function Documentation

template <class T_return, class T_arg1, class T_accumulator>
static result_type sigc::internal::signal_emit1<T_return, T_arg1, T_accumulator>::emit ( signal_impl impl,
typename type_trait<T_arg1>::take  _A_a1
[inline, static]
 

Executes a list of slots using an accumulator of type T_accumulator.

The arguments are buffered in a temporary instance of signal_emit1.

Parameters:
_A_a1 Argument to be passed on to the slots.
Returns:
The accumulated return values of the slot invocations as processed by the accumulator.

template <class T_return, class T_arg1, class T_accumulator>
T_return sigc::internal::signal_emit1<T_return, T_arg1, T_accumulator>::operator() ( const slot_type _A_slot  )  const [inline]
 

Invokes a slot using the buffered parameter values.

Parameters:
_A_slot Some slot to invoke.
Returns:
The slot's return value.
