> a feature can have requirements and capabilities, we use the OSGi interfaces
> for this. However, there is currently no easy way to match requirements and
> capabilities as these interfaces do not provide a method for it.
> For example, if you want to know whether a requirement is met by the
> available capabilities, that's not possible. While the OSGi specs provide a
> resolver that approach is way too heavy and not really suited for simple use
> cases. The resolver is used by the framework for bundle wiring.
> Therefore I propose we add a simple interface like
> MatchingRequirement extends Requirement {
> boolean match(Capability cap);
> }
> and this allows to match requirements and capabilities. As we're using Apache
> Felix utils for our reqs/caps, this method is already available there, so we
> don't have to implement this ourselves. Its just making it available
