## Detailed Description

### template <class T_functor>
struct sigc::adaptor_functor< T_functor >

Converts an arbitrary functor into an adaptor type.

All adaptor tyes in libsigc++ are unnumbered and have a `template operator()` member of every argument count they support. These functions in turn invoke a stored adaptor's `template operator()` processing the arguments and return value in a characteristic manner. Explicit function template instantiation is used to pass type hints thus saving copy costs.

adaptor_functor is a glue between adaptors and arbitrary functors that just passes on the arguments. You won't use this type directly.

The template argument T_functor determines the type of stored functor.
