      public AccessCacheGraph(org.jgrapht.DirectedGraph<org.emftext.language.java.classifiers.ConcreteClassifier,ClassAccessGraphEdge> accessGraph)
      Constructor of the access cache
      Parameters:
      accessGraph - A graph containing as nodes all GASTClasses considered in the Somox run and as edges the number of directed accesses between the two connected classes

  • Method Details

    • calculateNumberOfAccessesToClassesInSet

      public long calculateNumberOfAccessesToClassesInSet(Set<org.emftext.language.java.classifiers.ConcreteClassifier> sourceClasses, Set<org.emftext.language.java.classifiers.ConcreteClassifier> targetClasses)
      Counts all directed accesses from any of the source classes to any of the target classes. (Does not consider inverse accesses.)
      Parameters:
      sourceClasses - A set of source classes (nodes in the cache graph)
      targetClasses - A set of target classes (nodes in the cache graph)
      Returns:
      count of accesses The number of total accesses from sourceClasses to targetClasses

    • calculateNumberOfIncommingAccesses

      public long calculateNumberOfIncommingAccesses(Set<org.emftext.language.java.classifiers.ConcreteClassifier> sourceClasses)
      Compute the number of accesses coming from any class outside and going to the set of classes given
      Parameters:
      sourceClasses - A set of classes for which the incoming accesses are counted
      Returns:
      The total number of incoming accesses to the set of classes

    • calculateNumberOfExternalAccesses

      public long calculateNumberOfExternalAccesses(Set<org.emftext.language.java.classifiers.ConcreteClassifier> sourceClasses)
      Calculates the number of outgoing accesses of any class in 
       sourceClasses
      to any class not contained in source classes.
      Parameters:
      sourceClasses - The set of classes
      Returns:
      Count of accesses

    • calculateNumberOfInternalAccesses

      public long calculateNumberOfInternalAccesses(Set<org.emftext.language.java.classifiers.ConcreteClassifier> sourceClasses)
      Calculates the number of inner accesses of any class in 
       sourceClasses
      to any class contained in source classes.
      Parameters:
      sourceClasses -
      Returns:
      Count of accesses
