GraphListener (JGraphT : a free Java graph library)

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Superinterfaces:

java.util.EventListener, VertexSetListener<V>

All Known Implementing Classes:

ConnectivityInspector, NeighborCache
```
public interface GraphListener<V,E>
extends VertexSetListener<V>
```
A listener that is notified when the graph changes.
If only notifications on vertex set changes are required it is more efficient to use the VertexSetListener.
