NAME

std::experimental::packaged_task(libraryfundamentalsTS) - std::experimental::packaged_task(libraryfundamentalsTS)

Synopsis


Defined in header <experimental/future>
template< class > class packaged_task; //not defined (1) (library fundamentals TS)
template< class R, class ...Args > (2) (library fundamentals TS)
class packaged_task<R(Args...)>;


std::experimental::fundamentals_v1::packaged_task (and std::experimental::fundamentals_v2::packaged_task) is a modified version of std::packaged_task provided by the library fundamentals TS with support for type-erased allocators.

Member types


Member type Definition
allocator_type std::experimental::erased_type

Member functions


                    constructs the task object
constructor (public member function)
                    retrieves a pointer to the memory resource used by this object to allocate memory
get_memory_resource (public member function)


Non-member function


                                                          specializes the swap algorithm
std::experimental::swap(std::experimental::packaged_task) (function template)

Helper classes


                                                      specializes the std::uses_allocator type trait
std::uses_allocator<std::experimental::packaged_task> (class template specialization)


Members identical to std::packaged_task

Member functions


                          destructs the task object
destructor (public member function of std::packaged_task<R(Args...)>)
                          moves the task object
operator= (public member function of std::packaged_task<R(Args...)>)
                          checks if the task object has a valid function
valid (public member function of std::packaged_task<R(Args...)>)
                          swaps two task objects
swap (public member function of std::packaged_task<R(Args...)>)

Getting the result


                          returns a std::future associated with the promised result
get_future (public member function of std::packaged_task<R(Args...)>)

Execution


                          executes the function
operator() (public member function of std::packaged_task<R(Args...)>)
                          executes the function ensuring that the result is ready only once the current thread exits
make_ready_at_thread_exit (public member function of std::packaged_task<R(Args...)>)
                          resets the state abandoning any stored results of previous executions
reset (public member function of std::packaged_task<R(Args...)>)
