Package jasima.core.simulation

Class SimEvent

java.lang.Object

jasima.core.simulation.SimEvent

All Implemented Interfaces:

Comparable<SimEvent>, Runnable

Direct Known Subclasses:

SimEventMethodCall

public abstract class SimEvent
extends Object
implements Comparable<SimEvent>, Runnable

Abstract base class for all simulation events. Events are sequenced by an EventQueue according to their time, priority and event number (to enforce FIFO order of concurrent events with the same priority).

Constructor Detail

SimEvent

public SimEvent(double time,
                int prio)

SimEvent

public SimEvent(double time,
                int prio,
                String description)

Method Detail

run

public final void run()

Specified by:

run in interface Runnable

handle

public abstract void handle()

Override this method to implement the actual functionality.

setTime

public void setTime(double time)

getTime

public double getTime()

getPrio

public int getPrio()

setPrio

public void setPrio(int newPrio)

getDescription

public String getDescription()

setDescription

public void setDescription(String newDescription)

isAppEvent

public boolean isAppEvent()

An application event is the usual event type in a simulation. A simulation is terminated if the event queue is empty or does not contain any application events (i.e. isAppEvent() of all events in the queue returns false).

eventType

public SimOperations.SimEventType eventType()

compareTo

public final int compareTo(SimEvent o)

Specified by:

compareTo in interface Comparable<SimEvent>

toString

public String toString()

Overrides:

toString in class Object
