Class Generics

java.lang.Object
  y.util.Generics

public final class Generics
extends Object

Utility class with static methods that can be used to conveniently iterate over a graph's structure using Java 5's enhanced for loop. E.g.:

  for (Node node : nodes(graph)) {
    for (Edge edge : outEdges(node)) {
      System.out.println(edge);
    }
  }
 

This can be achieved by statically importing the utility methods of this class into your source file.
