all parameters in this class are optional :-)
Can you add javadocs to the new methods, like in the methods above?
> Vertex-centric iteration extensions

> Key: FLINK-1523
> URL: https://issues.apache.org/jira/browse/FLINK-1523
> Project: Flink
> Issue Type: Improvement
> Components: Gelly
> Reporter: Vasia Kalavri
> Assignee: Andra Lungu
>
> We would like to make the following extensions to the vertex-centric
> iterations of Gelly:
> - allow vertices to access their in/out degrees and the total number of
> vertices of the graph, inside the iteration.
> - allow choosing the neighborhood type (in/out/all) over which to run the
> vertex-centric iteration. Now, the model uses the updates of the in-neighbors
> to calculate state and send messages to out-neighbors. We could add a
> parameter with value "in/out/all" to the {{VertexUpdateFunction}} and
> {{MessagingFunction}}, that would indicate the type of neighborhood.
