[cdi-dev] [JBoss JIRA] (CDI-729) Async event not CompletionStage friendly
[
https://issues.jboss.org/browse/CDI-729?page=com.atlassian.jira.plugin.sy...
]
Romain Manni-Bucau commented on CDI-729:
----------------------------------------
[~mkouba] how do you embrace the rich semantic without the stage as a param? If you drop
it then it means you just use thenCompose which is a very small portion of the API. No
acceptEither etc...
If they are notified in parallel you get N stages and can replace the
"submitted" stage by the returned one to notify the completion to the caller.
This is the goal of the returned instance.
In summary: param = rich compose API with fallback support etc, returned type = enrichment
of the "wait" logic of the returned instance to the caller to give caller the
guarantee all is execpted (= same guarantee than in sync mode but reactive style)
Async event not CompletionStage friendly

Key: CDI-729
URL: https://issues.jboss.org/browse/CDI-729
Project: CDI Specification Issues
Issue Type: Feature Request
Reporter: Romain Manni-Bucau
The goal of this ticket is to enable user to get injected the completion future instead
of the raw event and return another completion stage (generic type ignored) to enable the
"chain" to be synched.
Here is a sample:
1. fireAsync(persistEvent)
2. observer implementation does: return future.thenCompose(db::doAsyncPersist)
3. when the user gets back the result of the fireAsync the doAsyncPersist is completed.
