Class NetworkGenerator

java.lang.Object

jline.gen.NetworkGenerator

public class NetworkGenerator
extends Object

A generator object that generates queueing network models based on user specification. Characteristics of generated models can be configured via the generator's properties.

Method Details

setSeed

public NetworkGenerator setSeed(long seed)

Reseeds the shared MatlabRandom stream, as MATLAB rng(seed). Every draw, randGraph included, comes from that stream, so the model matches MATLAB's. MATLAB seeds BEFORE constructing the generator, whose topology check already draws (5 draws for randGraph); call MatlabRandom.rng(long) first to reproduce that order.

Returns:

this generator (for chaining)
