Avery Ching commented on GIRAPH-47:
-----------------------------------
Sorry if I wasn't clear, but we could do away with the Configurable
workerObject and instead have a method in BasicVertex:
WorkerContext getWorkerContext();
While you may be blocked by GIRAPH-36 for your test, you can still try this out
on the unittests as they do use the pre/post/application/superstep methods
(i.e. SimplePageRankVertex). I've modified the interface slightly to give the
Context at the beginning.
{code}
public interface WorkerContext {
void initialize(Context context); // Called before anything done on this
worker
void close(); // Called when worker is done
void preSuperstep(); // Called before compute() on any vertex
void postSuperstep(); // Called after all vertices have run compute()
}
{code}
> Export Worker's Context/State to vertices through
> pre/post/Application/Superstep

> Project: Giraph
> Issue Type: Improvement
> Components: graph
> Affects Versions: 0.70.0
> Reporter: Claudio Martella
>
> 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.
