Avery Ching commented on GIRAPH-47:
-----------------------------------
I was thinking about the later approach that you mentioned
((MyEmitterWorkerContext)this.getWorkerContext()).emit(mydata). I doubt the
cast is that expensive, it's not boxing/unboxing. If there is a cleaner way to
do it that would allow users to do pretty much anything with their
WorkerContext, I'm open to it. But this should work.
> Export Worker's Context/State to vertices through
> pre/post/Application/Superstep

> It would be quite useful for vertices to reach some worker-related
> information stored i.e. in the GraphState class.
> This information could be exported as a parameter to
> pre/post/Application/Superstep like this:
> public void preApplication(Configurable workerObject);
> public void postApplication(Configurable workerObject);
> public void preSuperstep(Configurable workerObject);
> public void postSuperstep(Configurable workerObject);
> public Configurable getWorkerObject();
> Another possibility is to add a Context inner class to BasicVertex to store
> this information.
