 Event (Priority p=Default_Pri, Flags f=0)
bool scheduled () const
 Determine if the current event is scheduled. More...
void squash ()
 Squash the current event. More...
bool squashed () const
 Check whether the event is squashed. More...
bool isExitEvent () const
 See if this is a SimExitEvent (without resorting to RTTI) More...
bool isManaged () const
 Check whether this event will auto-delete. More...
bool isAutoDelete () const
 The function returns true if the object is automatically deleted after the event is processed. More...
Tick when () const
 Get the time that the event is scheduled. More...
Priority priority () const
 Get the event priority. More...
virtual BaseGlobalEventglobalEvent ()
 If this is part of a GlobalEvent, return the pointer to the Global Event. More...
void serialize (CheckpointOut &cp) const override
 Serialize an object. More...
void unserialize (CheckpointIn &cp) override
 Unserialize an object. More...
virtual ~Event ()
virtual const std::string name () const

Additional Inherited Members

- Public Types inherited from EventBase
typedef int8_t Priority
- Static Public Member Functions inherited from Serializable
static const std::string & currentSection ()
 Gets the fully-qualified name of the active section. More...
static void serializeAll (const std::string &cpt_dir)
 Serializes all the SimObjects. More...
static void unserializeGlobals (CheckpointIn &cp)
- Static Public Attributes inherited from EventBase
static const Priority Minimum_Pri = SCHAR_MIN
 Event priorities, to provide tie-breakers for events scheduled at the same cycle. More...
static const Priority Debug_Enable_Pri = -101
 If we enable tracing on a particular cycle, do that as the very first thing so we don't miss any of the events on that cycle (even if we enter the debugger). More...
static const Priority Debug_Break_Pri = -100
 Breakpoints should happen before anything else (except enabling trace output), so we don't miss any action when debugging. More...
static const Priority CPU_Switch_Pri = -31
 CPU switches schedule the new CPU's tick event for the same cycle (after unscheduling the old CPU's tick event). More...
static const Priority Delayed_Writeback_Pri = -1
 For some reason "delayed" inter-cluster writebacks are scheduled before regular writebacks (which have default priority). More...
static const Priority Default_Pri = 0
 Default is zero for historical reasons. More...
static const Priority DVFS_Update_Pri = 31
 DVFS update event leads to stats dump therefore given a lower priority to ensure all relevant states have been updated. More...
static const Priority Serialize_Pri = 32
 Serailization needs to occur before tick events also, so that a serialize/unserialize is identical to an on-line CPU switch. More...
static const Priority CPU_Tick_Pri = 50
 CPU ticks must come after other associated CPU events (such as writebacks). More...
static const Priority CPU_Exit_Pri = 64
 If we want to exit a thread in a CPU, it comes after CPU_Tick_Pri. More...
static const Priority Stat_Event_Pri = 90
 Statistics events (dump, reset, etc.) come after everything else, but before exit. More...
static const Priority Progress_Event_Pri = 95
 Progress events come at the end. More...
static const Priority Sim_Exit_Pri = 100
 If we want to exit on this cycle, it's the very last thing we do. More...
static const Priority Maximum_Pri = SCHAR_MAX
 Maximum priority. More...

Flags getFlags () const
bool isFlagSet (Flags _flags) const
void setFlags (Flags _flags)
void clearFlags (Flags _flags)
void clearFlags ()
virtual void trace (const char *action)
 This function isn't really useful if TRACING_ON is not defined. More...
const std::string instanceString () const
 Return the instance number as a string. More...
void acquire ()
 Memory management hooks for events that have the Managed flag set. More...
void release ()
 Managed event removed from the event queue. More...
virtual void acquireImpl ()
virtual void releaseImpl ()
