[jira] [Commented] (GIRAPH-47) Export Worker's Context/State to
vertices through pre/post/Application/Superstep
[ https://issues.apache.org/jira/browse/GIRAPH-47?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13120815#comment-13120815 ]
Claudio Martella commented on GIRAPH-47:
----------------------------------------
I'm very much in need for this feature. I'm willing to implement this with a little guidance (mostly a decision about what to store into this object).
What I'd do would be one of the two:
a) pass directly Mapper.Context (greedy approach, that's exactly what I need)
b) our own Context class to be defined. In that case we should discuss the interface.

> 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.
