  • Method Details

    • createGraphWithoutNullEdges

      public static Graph createGraphWithoutNullEdges(Graph graph)
      Create a graph from the given graph that contains no null edges.
      Parameters:
      graph - the given graph
      Returns:
      graph that contains no null edges

    • createDisplayGraph

      public static Graph createDisplayGraph(Graph graph, ResamplingEdgeEnsemble ensemble)
      Create a graph for displaying and print out.
      Parameters:
      graph - a Graph object
      ensemble - a ResamplingEdgeEnsemble object
      Returns:
      a Graph object

    • createGraphWithHighProbabilityEdges

      public static Graph createGraphWithHighProbabilityEdges(List<Graph> graphs)
      Combine all the edges from the list of graphs onto one graph with the edge type that has the highest frequency probability.
      Parameters:
      graphs - list of graphs
      Returns:
      graph containing edges with edge type of the highest probability

    • getReversed

      public static EdgeTypeProbability.EdgeType getReversed(EdgeTypeProbability.EdgeType edgeType)
      Returns the reversed counterpart of the specified edge type. The reversal mapping is defined as follows: - EdgeType.ac is reversed to EdgeType.ca - EdgeType.at is reversed to EdgeType.ta - EdgeType.ca is reversed to EdgeType.ac - EdgeType.ta is reversed to EdgeType.at For any other edge type, the method returns the input edge type unchanged.
      Parameters:
      edgeType - the edge type to be reversed
      Returns:
      the reversed edge type, or the input edge type if no reversal is defined
