Activator
public Activator()
init
public void init(BundleContext context,
DependencyManager dm)
throws Exception
- Initialize our DependencyManager Runtime service.
We depend on the OSGi LogService, and we track all started bundles which do have a
"DependencyManager-Component" Manifest header.
If the "dm.runtime.log=true" parameter is configured in the Felix config.properties
then we'll use a required/temporal service dependency over the log service.
This temporal dependency avoids us to be restarted if the log service is temporarily
unavailable (that is: when the log service is updating).
if the "dm.runtime.log" is not configured or it it is set to false, then we'll use
an optional dependency over the log service, in order to use a NullObject in case
the log service is not available.
