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.

  • Constructor Details

    • NetworkGenerator

      public NetworkGenerator()
      Constructor with default settings

    • NetworkGenerator

      public NetworkGenerator(String schedStrat, String routingStrat, String distribution, String cclassJobLoad, boolean hasVaryingServiceRates, boolean hasMultiServerQueues, boolean hasRandomCSNodes, boolean hasMultiChainCS, Function<Integer,Matrix> topologyFcn)
      Constructor with custom settings

    • NetworkGenerator

      public NetworkGenerator(String schedStrat, String routingStrat, String distribution, String cclassJobLoad, boolean hasVaryingServiceRates, boolean hasMultiServerQueues, boolean hasRandomCSNodes, boolean hasMultiChainCS, boolean initializeStates, Function<Integer,Matrix> topologyFcn)

  • Method Details

    • setSeed

      public NetworkGenerator setSeed(long seed)
      Reseeds this generator's internal random source for reproducible generation. Note: the randGraph topology uses a separate static random source; use a deterministic topology (e.g. cyclicGraph) for fully reproducible output.
      Parameters:
      seed - the seed value
      Returns:
      this generator (for chaining)

    • generate
