Class Simulation

java.lang.Object
simEngine.Simulation
public class Simulation extends Object
This class creates a new Simulation. It provides an easy way to initialize the jmt engine.
Author:
Federico Granata, Stefano Omini, Bertoli Marco Modified by Ashanka (May 2010): Patch: Multi-Sink Perf. Index Description: Added new Performance index for capturing 1. global response time (ResponseTime per Sink) 2. global throughput (Throughput per Sink) each sink per class.
