      public AbstractMetric()

  • Method Details

    • computeDirected

      public void computeDirected(ClusteringRelation relationToCompute)
      Description copied from interface: IMetric
      Computes the metric for the given clustering relation and stores the value in it
      Specified by:
      computeDirected in interface IMetric

    • getLaunchConfigurationTab

      public MetricTab getLaunchConfigurationTab()
      Description copied from interface: IMetric
      Returns the GUI launch configuration tab that can be used to configure the metric. Override if the metric supplies a tab
      Specified by:
      getLaunchConfigurationTab in interface IMetric

    • getMetricParameters

      public ParameterDescriptor[] getMetricParameters()
      Description copied from interface: IMetric
      The parameters needed by this metric for its computation. Parameters will be shown on the UI and their values will be passed to the metric during initialization of the metric
      Specified by:
      getMetricParameters in interface IMetric
      Returns:
      A list of parameter descriptors for the parameters of this metric

    • isCommutative

      public abstract boolean isCommutative()
      Specified by:
      isCommutative in interface IMetric
      Returns:
      true if the metric gives the same result if firstComponent and secondComponent are swapped

    • initialize

      public void initialize(Root gastModel, SoMoXConfiguration somoxConfiguration, Map<MetricID,IMetric> allMetrics, org.jgrapht.graph.DefaultDirectedGraph<tools.mdsd.jamopp.model.java.classifiers.ConcreteClassifier,ClassAccessGraphEdge> accessGraph, ComponentToImplementingClassesHelper componentToClassHelper)
      Description copied from interface: IMetric
      Initializes the Metric. Must be called before metrics are computed. Should be called again, if the model changed
      Specified by:
      initialize in interface IMetric
      Parameters:
      gastModel - the Root object of the GAST model
      somoxConfiguration - the configuration of the metric computation
      allMetrics - A map of all metrics available in the running SoMoX instance, maps metricID to Metric implementation
      accessGraph - A graph which contains the number of accesses from the source GASTClass to the target GASTClass for all edges in the
      componentToClassHelper - Helper initialized graph
