Method Detail

schedule

public static void schedule(Event event,
                            double timeDelay)

This schedule method places an event on the Future Event List (FEL) for later execution. Event are ordered first by their event time, and next by priority. In this case all events have the same priority (MID_PRIORITY).

Parameters:

event - event to schedule

timeDelay - how far in the future to schedule the event

schedule

public static void schedule(Event event,
                            double timeDelay,
                            int priority)

This schedule method places an event on the Future Event List (FEL) for later execution. Event are ordered first by their event time, and next by priority.

Parameters:

event - event to schedule

timeDelay - how far in the future to schedule the event

priority - priority of the event (low = 0, high = 10)

startSim

public static void startSim()

Start the simulation by processing the first event and subsequent events.

currentTime

public static double currentTime()

Return the current time in the simulation.

Returns:

double the current time
