STREAMS-388
> ActivityObjectConverter
> -----------------------
>
> Key: STREAMS-385
> URL: https://issues.apache.org/jira/browse/STREAMS-385
> Project: Streams
> Issue Type: New Feature
> Reporter: Steve Blackmon
> Assignee: Steve Blackmon
>
> The ActivityConverter interface and ActivityConverter{Util, Processor}
> classes in streams-converter allow modules to register classes to assist in
> conversion of non-activity event streams to activity event streams.
> This framework could also be applied to convert streams of external entities
> to/from ActivityObject.
> Add this interface, implement helper classes, and update at least one module
> to use it.
