Class Timed

java.lang.Object
  hu.mta.sztaki.lpds.cloud.simulator.Timed

All Implemented Interfaces:

Comparable<Timed>

Direct Known Subclasses:

DeferredEvent, EnergyMeter, MonitorConsumption, ResourceSpreader.FreqSyncer

public abstract class Timed
extends Object
implements Comparable<Timed>

This is the base class for the simulation, every class that should receive timing events should extend this and implement the function named "tick".
