Description

Graph visit could produce output objects, taking inspiration form DbUtil's ResultSetHandler and AsyncHttpClient's AsyncHandler it would be possible invoke:

final List<V> visited = visit( inputGraph ).from( startVertex ).applyingDepthFirstSearch( new MyHandler() );

just adding a callback method in GraphVisitHandler, something like:

public interface GraphVisitHandler<V extends Vertex, E extends Edge, G extends Graph<V, E>, O>
{

    [...]

    O onCompleted();

}
