Constructors:

CNEventBaseSched();

CNEventBaseSched(CNParam *);

CNSimTime::time();

Returns the simulation time.

CNStatistics *statistics() const;

void statistics(CNStatistics *st);

Sets/Gets the (optional) scheduler statistic. By default no statistic is used.

void delete_events_from(CNEventHandler *h);

void delete_events_to(CNEventHandler *h);

Deletes the events coming from or adressed to the eventhandler h. The following functions are defined virtual and must be defined in derived classes:

void add_event(CNEvent *ev)=0;

void send_event(CNEvent *ev)=0;

Adds/sends an event to an event handler.

void delete_event(CNEventID id)=0;

Deletes event with ID id.

void delete_events(CNEventHandler *evh, bool to=TRUE)=0;

Deletes all events from the list that are addressed to or are comming from event handler evh.

CNEvent *peek_event()=0;

CNEvent *peek_event(CNEventID id)=0;

Peeks at next event or event with ID id. Returns pointer to event, or NIL if not available.

CNEvent *next_event() = 0;

Retrieves next event from internal data structure.

void start();

void start(CNEvent *ev);

Starts the scheduler with an optional initialization event.

void stop()=0;

Stops the scheduler after processing the current event and deletes all pending events in the event list. May be used inside an event handler to stop the simulation.

CNEventIterator *create_iterator() = 0;

void process_events();

Process all events.

void process_now();
