Method edgeToIncidentNodesString

output/java_guava/1.4.17/Graphs.java:467–482

Returns a function that transforms an edge into a string representation of its incident nodes in graph. The function's apply method will throw an IllegalArgumentException if graph does not contain edge.

  private static Function<Object, String> edgeToIncidentNodesString(final Network<?, ?> graph) {
    if (graph.isDirected()) {
      return new Function<Object, String>() {
        @Override

          return String.format("<%s -> %s>", graph.source(edge), graph.target(edge));
        }
      };
    }

      @Override
      public String apply(Object edge) {
        return graph.incidentNodes(edge).toString();
