Jakob Homan commented on GIRAPH-192:
------------------------------------
(also, it's not necessary to delete the previous version of the patch when
attaching a new one. JIRA will go ahead and grey out the older versions and
it's good to keep them around to avoid confusion.)
> Move aggregators to a seperate sub-package

> Since aggregators will be re-used throughout many projects and algorithms, it
> makes sense to implement the most common ones in a separate sub-package. This
> will reduce the time required for users when they implement their projects
> based on Giraph, because the required aggregators are already in place. I
> implemented the following ones:
> for int/long/float/double: min, max, product, sum, overwrite
> for boolean: and, or, overwrite
> Most of them speak for themselves, except for the overwrite one. This
> aggregator simply overwrites the stored value when a new value is aggregated.
> This is useful when one node is in some way a master node (for example a
> source node in an routing algorithm), and this node wants to broadcast a
> value to all other nodes.
> Attached is a patch against trunk implementing the aggregators and patching
> some existing files so they use the .aggregators package instead of the
> .examples one.
