Subject [jira] [Commented] (S4-5) Prototype app builder
Date Thu, 16 Feb 2012 01:37:00 GMT

    [ https://issues.apache.org/jira/browse/S4-5?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13209055#comment-13209055

Matthieu Morel commented on S4-5:
---------------------------------

I ported a simple example to this API and it seems to work nicely.

Notes:
- "onField" should rather be named "onStream" no?
- for dispatching to several types of PEs, you currently need to write .to("1").to("2") right?
would it be possible to write .to("1", "2") ?
- the "stream" component has now disappeared from the API. Shouldn't it be included? It may
be nicer to define streams as first class entities and include the key finder in their definition
(instead of writing "emit.onField.withKeyFinder")
- edsl depends on core, that makes it impossible to write app-level tests in core that would
use the fluent API. Not sure it's an issue though.

> Extend Guice AbstractModule to create a simple application builder layer. The idea is
to evaluate if we can use Guice to do all the wiring including PEs and Streams and Apps.
