VertexUpdateFunction

[rostami]

Hi,

I want to write an iterative algorithm using Gelly (spargel), like:
https://ci.apache.org/projects/flink/flink-docs-release-0.8/spargel_guide.html

My question is how I can access the actual vertex information like the  
vertex degree (in- or outdegree)
under the subclass of VertexUpdateFunction. A way is maybe to send an  
instance of graph to the constructor.
However, getting the degree for a vertex in each instance of this  
subclass would be really inefficient.

Thanks,
Ali
