| bool DREAM::FixedPriorityScheduler::nonpreemptive | ( | ) | const [virtual] |

| void DREAM::FixedPriorityScheduler::schedule | ( | bool | deterministic | ) | throw (DREAM::Exception) [virtual] |
Schedules a Node for execution.
This function will choose the highest subpriority Node in the highest priority frame and schedule it for execution by calling Node::execute (). Multiple Tasks will be scheduled from multi-threaded Lanes on a multiprocessor platform.
| deterministic | specifies whether randomness is allowed. |
