    • getGraph

      public org.jgrapht.Graph<IStatement,org.jgrapht.graph.DefaultEdge> getGraph()
      Gets the dependency graph. Graph direction: dependent object → dependency (source → target)
      Returns:
      the dependency graph

    • getReversedGraph

      public org.jgrapht.graph.EdgeReversedGraph<IStatement,org.jgrapht.graph.DefaultEdge> getReversedGraph()

    • getDb

      public IDatabase getDb()
      Copied database, graph source.
      Do not modify any elements in this as it will break HashSets/HashMaps and with them the generated graph.

      public void addCustomDepcies(List<Map.Entry<IStatement,IStatement>> depcies)
      Adds custom dependencies to the graph.
      Parameters:
      depcies - list of custom dependency pairs to add
