[jira] [Commented] (GIRAPH-509) Factor out AggregatorUsage

["Nitay Joffe (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GIRAPH-509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13573176#comment-13573176 ] 

Nitay Joffe commented on GIRAPH-509:
------------------------------------

+1.

Just curious, we have:
<A extends Writable> A getAggregatedValue(String name);

When it could just return Writable?


I take it to mean we prefer doing:
foo.<LongWritable>getAggregatedValue("a")

over:
(LongWritable)getAggregatedValue("a")

Why?
