}Expand description
Access to the neighbors of each node, through incoming or outgoing edges.
Depending on the graph’s edge type, the neighbors of a given directionality are:
Directed,Outgoing: All targets of edges froma.Directed,Incoming: All sources of edges toa.Undirected: All other endpoints of edges connected toa.
