~~ ChangeLog (28.3.11)

• Transformations
  • interface Transformation, partial implementation TransformationImpl
  • can be used to change a graph after generating it using a network generator
  • e.g. GiangConnectedComponent removes all nodes except for the largest cluster
  • e.g. Bidirectional makes all conenctions bidirectional by adding the reverse edges as well
  • e.g. RandomWithSameDD created a random network with the same degree distribution
    • basically the same as gtna.networks.transformation.SameDD
  • NetworkImpl constructor now includes an array of transformations
  • gtna.networks.transformation hence removed
  • all these transformation are automatically applied during Series.generate()
  • can use parameters similar to RoutingAlgorithm and Network
• Metric dependencies
  • metrics can now be configured to declare dependencies
  • KEY_DEPENDENCY = DD, CC requires DD and CC to be executed before
• computed metrics
  • computeData method now includes a third parameter: Hashtable<String, Metric> m
  • contains all metrics computed so far to gain access to the computed data
  • removed method readData and readValues from the Metric interface and MetricImpl
• Routing
  • added Route class to represent the results from each individual routing attempt
    • adapted the interfaces and implementations where neccessarey
  • reorganized
  • many new nodes / identifiers / algorithms added
• Plots
  • Gnuplot output can now be customized in the configuration file
  • plot via EPS feature was removed
• MAIN_DATA_FOLDER & MAIN_PLOT_FOLDER
  • all data is stored in the folder Config.get("MAIN_DATA_FOLDER")
    • default is "./data/"
    • can be changed, e.g., using Config.overwrite("MAIN_DATA_FOLDER", "./data/myData");
  • all plots are stored in the folder Config.get("MAIN_PLOT_FOLDER");
    • default is "./plots/"
    • can be changed, e.g., using Config.overwrite("MAIN_PLOT_FOLDER", "./plots/myPlots");
    • all plots like, e.g., Plot.plotAll(s, "destination/") are then stored in "MAIN_PLOT_FOLDER" + "destination/"
    • therefore no need to always plot to "./plots/myPlots/destination/"
• Config files
  • reorganized
  • added examples, explanations, and comments to many files
• Comments
  • comments to explain part of the classes and implementations were added
• Cleanup
  • some classes / functionalities were merged
  • unneccessary classes were removed
  • some classes were renamed and/or moved
  • some additional interfaces were slightly changed to reflect other changes mentioned above
