std::packaged_task

Member functions

packaged_task::packaged_task

packaged_task::~packaged_task

packaged_task::operator=

packaged_task::valid

packaged_task::swap

Getting the result

packaged_task::get_future

Execution

packaged_task::operator()

packaged_task::make_ready_at_thread_exit

packaged_task::reset

 

packaged_task& operator=(const packaged_task&) = delete;	(1)
packaged_task& operator=(packaged_task&& rhs)	(2)

1) Copy assignment operator is deleted, std::packaged_task is move-only.

Note: C++11 does not specify const here, this is the defect 2067.

2) Releases the shared state, if any, destroys the previously-held task, and moves the shared state and the task owned by rhs into *this. rhs is left without a shared state and with a moved-from task.

Parameters

rhs

-

the std::packaged_task to move from

Exceptions

2)

noexcept specification:  

noexcept

  (since C++11)
