Member functions
constructs a new std::experimental::function instance (public member function) |
|
| assigns a new target (public member function) |
|
| swaps the contents (public member function) |
|
|
(removed in library fundamentals TS v3)
|
retrieves a pointer to the memory resource used by this object to allocate memory (public member function) |
|
(library fundamentals TS v3)
|
retrieves a type-erased std::pmr::polymorphic_allocator used by this object to allocate memory (public member function) |
Non-member functions
specializes the swap algorithm (function template) |
|
|
(removed in library fundamentals TS v3)
|
compares an std::experimental::function with nullptr (function template) |
Helper classes
|
(removed in library fundamentals TS v3)
|
specializes the std::uses_allocator type trait (class template specialization) |

Member functions
destroys a std::function instance (public member function of std::function<R(Args...)>) |
|
| checks if a target is contained (public member function of std::function<R(Args...)>) |
|
| invokes the target (public member function of std::function<R(Args...)>) |
|
Target access | |
| obtains the typeid of the stored target (public member function of std::function<R(Args...)>) |
|
| obtains a pointer to the stored target (public member function of std::function<R(Args...)>) |
