Subject [jira] [Commented] (GIRAPH-47) Export Worker's Context/State to vertices through pre/post/Application/Superstep
Date Wed, 05 Oct 2011 19:46:29 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-47?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13121399#comment-13121399

Claudio Martella commented on GIRAPH-47:
----------------------------------------

Sounds very reasonable. We would then remove those methods from BasicVertex API I guess. I'll
work on this. Unfortunately I can't test it on my application as it's blocked by GIRAPH-36,
so I'll think about a toy-example to test this out.

One question: what would be this Configurable workerObject you'd pass to the WorkerContext
implementation?

> 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.
