  • Method Details

    • inDegreeOf

      public int inDegreeOf(V vertex)
      Description copied from interface: DirectedGraph
      Returns the "in degree" of the specified vertex. An in degree of a vertex in a directed graph is the number of inward directed edges from that vertex. See http://mathworld.wolfram.com/Indegree.html.
      Specified by:
      inDegreeOf in interface DirectedGraph<V,E>
      Parameters:
      vertex - vertex whose degree is to be calculated.
      Returns:
      the degree of the specified vertex.

    • incomingEdgesOf

      public Set<E> incomingEdgesOf(V vertex)
      Description copied from interface: DirectedGraph
      Returns a set of all edges incoming into the specified vertex.
      Specified by:
      incomingEdgesOf in interface DirectedGraph<V,E>
      Parameters:
      vertex - the vertex for which the list of incoming edges to be returned.
      Returns:
      a set of all edges incoming into the specified vertex.

    • outDegreeOf

      public int outDegreeOf(V vertex)
      Description copied from interface: DirectedGraph
      Returns the "out degree" of the specified vertex. An out degree of a vertex in a directed graph is the number of outward directed edges from that vertex. See http://mathworld.wolfram.com/Outdegree.html.
      Specified by:
      outDegreeOf in interface DirectedGraph<V,E>
      Parameters:
      vertex - vertex whose degree is to be calculated.
      Returns:
      the degree of the specified vertex.

    • outgoingEdgesOf

      public Set<E> outgoingEdgesOf(V vertex)
      Description copied from interface: DirectedGraph
      Returns a set of all edges outgoing from the specified vertex.
      Specified by:
      outgoingEdgesOf in interface DirectedGraph<V,E>
      Parameters:
      vertex - the vertex for which the list of outgoing edges to be returned.
      Returns:
      a set of all edges outgoing from the specified vertex.
