task_group() |
Constructs an empty task group. |
~task_group() |
Requires: Method wait must be called before destroying a task_group, otherwise the destructor throws an exception. |
template<typename Func> void run( const Func& f ) |
Spawn a task that computes f() and return immediately. |
template<typename Func> void run ( task_handle<Func>& handle ); |
Spawn a task that computes handle() and return immediately. |
template<typename Func> void run_and_wait( const Func& f ) |
Equivalent to {run(f); wait();}, but guarantees that f runs on the current thread. NoteTemplate method run_and_wait is intended to be more efficient than separate calls to run and wait. |
template<typename Func> void run _and_wait( task_handle<Func>& handle ); |
Equivalent to {run(handle); wait();}, but guarantees that handle() runs on the current thread. NoteTemplate method run_and_wait is intended to be more efficient than separate calls to run and wait. |
task_group_status wait() |
Wait for all tasks in the group to complete or be cancelled. Returns: True if this task group is cancelling its tasks. |
bool is_canceling() |
Returns: True if this task group is cancelling its tasks. |
void cancel() |
Cancel all tasks in this task_group. |
