Examples of org.gephi.graph.api.Edge

org.gephi.graph.api.Edge
Edge interface. An edge connects two nodes and can be directed or not.
If working with several {@link GraphView}, note that source and target are always nodes in the main view. To obtain nodes in other views, do:
```
 GraphView view = ...; Node node = node.getNodeData().getNode(view.getViewId()); 
```
