[equinox-dev] Provide capability question
|
Hi,
I have two question about Provide capability and Require-Capability.
Background: you declare that you provide ds in version 1.2 via the
following snippet in your MANIFEST.MF
Provide-Capability: osgi.extender;
osgi.extender="osgi.component";
version:Version="1.2";
uses:="org.osgi.service.
A plug-in which requires his capablitiy defines the following:
Require-Capability: osgi.extender;
filter:="(&(osgi.extender=osgi.component)(version>=1.2)(!(version>=2.0)))"
The first question is: Where is this defined that these are the
correct entries? I use
http://git.eclipse.org/c/equinox/rt.equinox.bundles.git/commit/?id=cff4c8e643032ce870dfc9e8279cd5fb16218f4e
to "remember" the correct way to define it, but I guess there is a
more general way.
The second question is. What is the correct way to use
Provide-Capability and Provide-Capability for my customer code? In my
example, I provide a service via DS and want to ensure that the
consumer is only started if the service is available. I think
Require-Capability is the correct way, but I have not seen an example
for a customer capability yet.
Best regards, Lars
