Examples of EdgeIterable

org.gephi.graph.api.EdgeIterable
Proxy iterable for iterating edges, users can either get EdgeIterator or directly getting an Edge array.
This iterable has an additionnal feature, it automatically lock the graph when the iterator is called and unlock it when iterator terminates. That means calling break before the iterator terminates won't unlock the graph. The doBreak() method will properly unlock the graph. Note that calling toArray() avoid this issue.
If you're not sure if the graph is properly unlocked, for instance when exception are thrown within the loop, use {@link Graph#readUnlockAll()}. @author Mathieu Bastian @see Graph#readLock()

                //Get the next Node and add it to the component list
                Node u = Q.removeFirst();
                component.add(u);


                //Iterate over all of u's neighbors
                EdgeIterable edgeIter = hgraph.getEdgesAndMetaEdges(u);


                //For each neighbor
                for (Edge edge : edgeIter) {
                    Node reachable = hgraph.getOpposite(u, edge);
                    int id = indicies.get(reachable);
