Converts an arbitrary functor into an adaptor type.
All adaptor types in libsigc++ 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.
