Constructor Detail

Event

public Event()

Construct a new event.

Method Detail

simulation

public final Simulation simulation()

Returns the simulation in which this event occurs.

Returns:

Simulation.

time

public final double time()

Returns this event's simulation time, the time when this event is scheduled to take place.

Returns:

Simulation time.

doAt

public final void doAt(double t,
                       Event event)

Schedule the given event to be performed at the given time in this event's simulation.

Parameters:

t - Simulation time for event.

event - Event to be performed.

Throws:

java.lang.IllegalArgumentException - (unchecked exception) Thrown if t is less than the current simulation time.

java.lang.NullPointerException - (unchecked exception) Thrown if event is null.

doAfter

public final void doAfter(double dt,
                          Event event)

Schedule the given event to be performed at a time dt in the future (at current simulation time + dt) in this event's simulation.

Parameters:

dt - Simulation time delta for event.

event - Event to be performed.

Throws:

java.lang.IllegalArgumentException - (unchecked exception) Thrown if dt is less than zero.

java.lang.NullPointerException - (unchecked exception) Thrown if event is null.

perform

public abstract void perform()

Perform this event. Called by the Simulation when the simulation time equals the time when this event is scheduled to take place.
