List of all members.

## Static Public Member Functions

static T_return | call_it (slot_rep* rep)
| Invokes a functor of type `T_functor`.
static hook | address ()
| Forms a function pointer from call_it().

## Detailed Description

### template <class T_functor, class T_return>
struct sigc::internal::slot_call0< T_functor, T_return >

Abstracts functor execution.

call_it() invokes a functor of type T_functor with a list of parameters whose types are given by the template arguments. address() forms a function pointer from call_it().

The following template arguments are used:

- T_functor The functor type.
- T_return The return type of call_it().
