## Detailed Description

### template <class T_emitter, class T_result = typename T_emitter::result_type>
struct sigc::internal::slot_iterator_buf< T_emitter, T_result >

Special iterator over sigc::internal::signal_impl's slot list that holds extra data.

This iterators is for use in accumulators. operator*() executes the slot. The return value is buffered, so that in an expression like

     a = (* i)* (* i);

the slot is executed only once.
