Tuomas Kiviaho updated FELIX-3949:
----------------------------------
Attachment: ComponentImpl.patch
> ServiceDependency declaration without service name
> --------------------------------------------------
>
> Key: FELIX-3949
> URL: https://issues.apache.org/jira/browse/FELIX-3949
> Project: Felix
> Issue Type: Improvement
> Components: Dependency Manager
> Reporter: Tuomas Kiviaho
> Priority: Minor
> Attachments: ComponentImpl.patch, ServiceDependencyImpl.patch
>
>
> I'd like to track 'org.apache.ace.identification.Identification' instances in
> order to pull out properties from respective service references. Problem is
> that in order to do this I'd have to import the ACE specific package even
> when I'm only interested in the service reference properties.
> I tried to be clever and use only filter to achieve the this but noticed that
> service name is always required although service tracker could function
> happily only with service name.
> ServiceDependencyImpl has this restriction only in start(DependencyService)
> and for this reason setService() method forces the service name to be
> Object.class when I only declare the service filter. This causes the actual
> filter to be padded with (OBJECTCLASS=java.langObject) which is the reason
> why my attempt did not work.
> By fixing these two places, the service name could be made optional.
> TemporalServiceDependencyImpl should also verify that the service name has
> actually been declared and ComponentImpl.configureImplementation should allow
> field injection even when service name hasn't been declared.
