	DVFS update event leads to stats dump therefore given a lower priority to ensure all relevant states have been updated. More...

Member Function Documentation

void Event::acquire ( )

inlineprotected

Memory management hooks for events that have the Managed flag set.

Events can use automatic memory management by setting the Managed flag. The default implementation automatically deletes events once they have been removed from the event queue. This typically happens when events are descheduled or have been triggered and not rescheduled.

The methods below may be overridden by events that need custom memory management. For example, events exported to Python need to impement reference counting to ensure that the Python implementation of the event is kept alive while it lives in the event queue.

Note: Memory managers are responsible for implementing reference counting (by overriding both acquireImpl() and releaseImpl()) or checking if an event is no longer scheduled in releaseImpl() before deallocating it. Managed event scheduled and being held in the event queue.
