choice::choice Constructor

Constructs a choice messaging block.

explicit choice(
 _Type _Tuple
);
choice(
 Scheduler& _PScheduler,
 _Type _Tuple
);
choice(
 ScheduleGroup& _PScheduleGroup,
 _Type _Tuple
);
choice(
 choice && _Choice
);

Parameters

• _Tuple
  A tuple of sources for the choice.

• _PScheduler
  The Scheduler object within which the propagation task for the choice messaging block is scheduled.

• _PScheduleGroup
  The ScheduleGroup object within which the propagation task for the choice messaging block is scheduled. The Scheduler object used is implied by the schedule group.

• _Choice
  A choice messaging block to copy from. Note that the original object is orphaned, making this a move constructor.

Remarks

The runtime uses the default scheduler if you do not specify the _PScheduler or _PScheduleGroup parameters.

Move construction is not performed under a lock, which means that it is up to the user to make sure that there are no light-weight tasks in flight at the time of moving. Otherwise, numerous races can occur, leading to exceptions or inconsistent state.
