Integrate SCR with Felix
------------------------
Key: FELIX-132
URL: http://issues.apache.org/jira/browse/FELIX-132
Project: Felix
Issue Type: Improvement
Components: Declarative Services
Affects Versions: 0.8.0
Environment: org.apache.felix.scr project, Rev. 427625
Reporter: Felix Meschberger
Attachments: SCR_Activator_fm20060830.diff
Currently any bundle wanting to contribute components has to implement an
Activator extending the GenericActivator (or refer to the GenericActivator in
the Manifest.MF. Additionally start/stop semantics of the SCR bundle are not
implemented.
Attached is a patch, which enhances the current Activator class as follows:
* On start load components of active bundles
* On stop unload all loaded components
* listen for bundle state changes to load/unload components:
* on BundleEvent.STARTED: Components are loaded
* on BundleEvent.STOPPING: Components are unloaded
The BundleContext instance needed to load the Components is retrieved using the
BundleImpl.getContext() method, which is accessed through reflection on the
bundle instance.
As a consequence of this patch, the GenericActivator class may be rebuilt into
a proper component loader and need not be used as an activator for component
bundles.
