## Detailed Description

### template <class T_return, class T_arg1, class T_arg2, class T_arg3, class T_arg4, class T_arg5, class T_arg6, class T_arg7, class T_accumulator>
struct sigc::internal::signal_emit7< T_return, T_arg1, T_arg2, T_arg3, T_arg4, T_arg5, T_arg6, T_arg7, T_accumulator >

Abstracts signal emission.

This template implements the emit() function of signal7. Template specializations are available to optimize signal emission when no accumulator is used, i.e. the template argument T_accumulator is `nil`.

| ) | `[inline, static]`

  | Executes a list of slots using an accumulator of type T_accumulator. The arguments are buffered in a temporary instance of signal_emit7. Parameters:
  | _A_a1 | Argument to be passed on to the slots.
  | _A_a2 | Argument to be passed on to the slots.
  | _A_a3 | Argument to be passed on to the slots.
  | _A_a4 | Argument to be passed on to the slots.
  | _A_a5 | Argument to be passed on to the slots.
  | _A_a6 | Argument to be passed on to the slots.
  | _A_a7 | Argument to be passed on to the slots.
Returns: The accumulated return values of the slot invocations as processed by the accumulator.

  | Invokes a slot using the buffered parameter values. Parameters:
  | _A_slot | Some slot to invoke.
Returns: The slot's return value.
