Returns the nodes which have an incident edge in common with node in this graph.
Returns true if this graph allows self-loops (edges that connect a node to
itself). Attempting to ad
Returns all edges in this graph.
Returns true if there is an edge directly connecting nodeU to nodeV. This is
equivalent to nodes().c
Returns the count of node's incoming edges (equal to predecessors(node).size())
in a directed graph.
Returns true if the edges in this graph are directed. Directed edges connect a
Returns the order of iteration for the elements of #nodes().
Returns all nodes in this graph, in the order specified by #nodeOrder().
Returns the count of node's outgoing edges (equal to successors(node).size()) in
a directed graph. I
