Examples of jmt.engine.simEngine.Simulation

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