[cdi-dev] [JBoss JIRA] (CDI-650) Introduce asynchronous event notification options

Introduce asynchronous event notification options ------------------------------------------------- Key: CDI-650 URL: https://issues.jboss.org/browse/CDI-650 Project: CDI Specification Issues Issue Type: Feature Request Reporter: Martin Kouba Assignee: Martin Kouba Fix For: 2.0 .Final Currently, it's only possible to provide a custom executor when firing an event asynchronously - see also {{javax.enterprise.event.Event.fireAsync(U, Executor)}}. It might be useful to provide other implementation-specific options, e.g. notification timeout. Therefore, I suggest to introduce {{NotificationOptions}} interface: {code:java} public interface NotificationOptions { Executor getExecutor(); // Implementation-specific options Object get(String optionName); } {code} and change the method signature to: {code:java} <U extends T> CompletionStage<U> fireAsync(U event, NotificationOptions options); {code} In the future, if any implementation-specific configuration proves to be useful and worth standardizing, we may simply add a new method to {{NotificationOptions}}, e.g. {code:java} Duration getTimeout(); {code} instead of adding more and more params to {{Event.fireAsync()}}. We could also introduce some convenient static methods on {{NotificationOptions}}, e.g.: {code:java} void fireEvents(Event event, Executor executor) { event.fireAsync(new Foo(), NotificationOptions.ofExecutor(executor)); } {code}
