Detailed Description

template<typename R, typename... A>
class jau::func::null_target_t< R, A >

func::null_target_t implementation for no function.

identifiable as jau::func::target_type::null via jau::function<R(A...)>::type().

This special type is used for an empty jau::function instance w/o holding a function, e.g. when created with the default constructor.

Template Parameters

R	function return type
A	function arguments
