Constructor & Destructor Documentation

UT_TaskGroupContext::UT_TaskGroupContext ( KindType  relation_to_parent = BOUND)

Constructs an empty task_group_context.

If relation_to_parent is bound, the task_group_context will become a child of the innermost running task's group when it is first spawned. If this call is made directly from the user thread, the effect will be as if relation_to_parent were isolated. If relation_to_parent is isolated, it has no parent task_group_context.

Definition at line 45 of file UT_TaskGroup.h.

UT_TaskGroupContext::~UT_TaskGroupContext ( )

Destroys an empty task_group_context. The behavior is undefined if there are still extant tasks associated with this task_group_context.

Member Function Documentation

static void UT_TaskGroupContext::cancelCurrentGroupExecution ( )

Cancel the entire current task group context when run within a task.

Definition at line 81 of file UT_TaskGroup.h.

bool UT_TaskGroupContext::cancelGroupExecution ( )

Requests that tasks in group be cancelled.

False if group is already cancelled; true otherwise. If concurrently called by multiple threads, exactly one call returns true and the rest return false.

Definition at line 69 of file UT_TaskGroup.h.

bool UT_TaskGroupContext::isGroupExecutionCancelled ( ) const
True if group has received cancellation.

Definition at line 75 of file UT_TaskGroup.h.

void UT_TaskGroupContext::reset ( void  )

Reinitializes this to uncancelled state.

This method is only safe to call once all tasks associated with the group's subordinate groups have completed. This method must not be invoked concurrently by multiple threads.
