## Detailed Description

### template<class T_return, class T_arg1, class T_arg2>
template <class T_accumulator>
class sigc::signal< T_return(T_arg1, T_arg2)>::accumulated< T_accumulator >

Convenience wrapper for the numbered sigc::signal2 template.

Like sigc::signal but the additional template parameter T_accumulator defines the accumulator type that should be used.
