Example 21 with BundleCapability

use of org.osgi.framework.wiring.BundleCapability in project aries by apache.

the class SubsystemResolverHook method filterMatches.

public void filterMatches(BundleRequirement requirement, Collection<BundleCapability> candidates) {
    // Filter out candidates that don't come from preferred providers when
    // there is at least one preferred provider.

    // (2) For each candidate, ask each subsystem if the candidate or any of
    // the candidate's containing subsystems is a preferred provider. If at
    // least one preferred provider exists, filter out all other candidates
    // that are not also preferred providers.
    Collection<BundleCapability> preferredProviders = new ArrayList<BundleCapability>(candidates.size());
