Streams 168
There's quite a bit going on in this PR, so here's a summary:
To date, modules in streams-contrib have implemented interfaces from
streams-core. Code re-use has been intra-contrib-module, or occasionally
cross-contrib-module, with a few helper classes in streams-pojo playing a
supporting role.
This PR introduces a new top-level sub-module, streams-components, where
I've placed streams-http. streams-http contains a provider and a processor,
both of which can be employed in a stream to collect json documents from remote
REST endpoints. The config properties of streams-http were chosen to align
with camel's http support module, anticipating compatibility will be desirable
at some point in the future.
In addition, the PR contains new processors (in streams-provider-twitter
and streams-processor-peoplepattern) which employ streams-http to collect data
from specific data supplier endpoints, with a high degree of code reuse from
streams-http. Essentially they just override a few methods but do not need to
introduce their configuration or alter any aspect of the REST call other than
parameters and headers. I've built code that uses the provider as well.
The JSON responses from the REST calls in these reference processors are
then appended to specific extensions fields (activity.extensions.X,
activity.actor.extensions.X, activity.object.extensions.X, etc.. for arbitrary
X, sited on the activity or below (on any sub-node whose field extends
ActivityObject.) Utility classes supporting extensions are under
streams-pojo-extensions. Modules that were importing these classes from
streams-pojo would need to update to import streams-pojo-extensions as well.
Philosophically, future modules containing providers, processors, and
persisters which are both useful as standalone components in streams, and which
are designed to simplify/harden channel/API/database-specific components that
extend them, would be placed under streams-components. This gives us a
dedicated sub-partitioned module for valuable utility features (outside of
core), and will drastically curtail tendancies for one contrib module to
explicitly require another.
Lastly, I've built streams-example modules utilizing each of these
processors, which are pushed to w2ogroup/streams-examples under the STREAMS-168
branch.
I look forward to your feedback on this proposed reorg.
