-------------------------------------
Summary: Support for static field injections and callback
invocations
Key: FELIX-3912
URL: https://issues.apache.org/jira/browse/FELIX-3912
Project: Felix
Issue Type: Improvement
Components: Dependency Manager
Reporter: Tuomas Kiviaho
I've got a case (JUnit tests) where static field injections and callback
invocation would be more than welcome. I'm succesfully using DependencyManager
in the same manner as Sonatype Sisu for my integration tests, but test
execution times become quite high when using @TestRule instead of @ClassRule.
The codebase seems to be crafted statics in mind since there are only handful
of locations which prevent this. The biggest blocker is
Component.setImplementation that would need an information preventing
instantiation. The same information would be used to determine at callbacks and
field injections whether to perform these or not.
I guess that the most pain would come from annotation api where possibility of
method overloading should be taken into account, but that could get static
support later on.
I could provide a patch if this idea gets wind under it. Personally I dislike
the idea of using statics anywhere else that within unit/integration tests.
