> Key: SANDBOX-372

> Project: Commons Sandbox
> Issue Type: Improvement
> Components: Graph
> Reporter: Simone Tripodi
> Assignee: Simone Tripodi
>
> Graph visit could produce output objects, taking inspiration form DbUtil's
> [ResultSetHandler|http://commons.apache.org/dbutils/apidocs/org/apache/commons/dbutils/ResultSetHandler.html]
> and AsyncHttpClient's
> [AsyncHandler|http://sonatype.github.com/async-http-client/apidocs/com/ning/http/client/AsyncHandler.html]
> it would be possible invoke:
> {code}
> final List<V> visited = visit( inputGraph ).from( startVertex
> ).applyingDepthFirstSearch( new MyHandler() );
> {code}
> just adding a callback method in {{GraphVisitHandler}}, something like:
> {code}
> public interface GraphVisitHandler<V extends Vertex, E extends Edge, G
> extends Graph<V, E>, O>
> {
> [...]
> O onCompleted();
> }
> {code}
