template<class R,class...ArgTypes,class Alloc> struct uses_allocator<std::experimental::function<R(ArgTypes...)>, Alloc> | (library fundamentals TS) (removed in library fundamentals TS v3) | |
This specialization ofstd::uses_allocator informs other library components that all objects of typestd::experimental::function supportuses-allocator construction.

operator bool | converts the object tobool, returnsvalue (public member function) |
operator() (C++14) | returnsvalue (public member function) |
