Hummm... :-\
I was about to create a kind of extender provider tracking on the
subsystem capabilities... will need to rethink it then...
thanks BJ.

I doubt it. The region bundles don't provide or require the
capabilities themselves.
You will probably need to use the subsystem service to get the
subsystem manifest and parse the headers yourself.

Subject: [osgi-dev] How to get the custom capabilities provided by
a scoped subsystem ?
Date: Tue, May 16, 2017 4:46 PM
Hello OSGi experts,
In a subsystem manifest we can declare provided capabilities using the
header "Provide-Capability:".
I'm trying to get them using the bundle context from the subsystem
service (injected by DS):
> List<Capability> caps = pScopeSubsystem.getBundleContext()
> .getBundle().adapt(BundleRevision.class)
> .getCapabilities(null);
> for (Capability capability : caps) {
> System.out.println("Cap: " + capability.toString());
> }
Also tried BundleWiring:
> BundleWiring bw = pKernelSubsystem.getBundleContext().getBundle()
> .adapt(BundleWiring.class);
> List<BundleCapability> capabilities = bw.getCapabilities(null);
But the only capabilities that I was able to get are those:
> Cap: osgi.wiring.bundle; bundle-version:Version="1.0.0";
> osgi.wiring.bundle="org.osgi.service.subsystem.region.context.1"
> Cap: osgi.wiring.host; bundle-version:Version="1.0.0";
> osgi.wiring.host="org.osgi.service.subsystem.region.context.1"
> Cap: osgi.identity;
> osgi.identity="org.osgi.service.subsystem.region.context.1";
> type="osgi.bundle"; version:Version="1.0.0"
So, what is the way to get the custom capabilities declared for a
scope
subsystem?
many thanks,
Cristiano
