Class PackageAdminResolver

java.lang.Object

org.eclipse.gemini.blueprint.io.internal.resolver.PackageAdminResolver

All Implemented Interfaces:

DependencyResolver

public class PackageAdminResolver
extends Object
implements DependencyResolver

PackageAdmin based dependency resolver.

This implementation uses the OSGi PackageAdmin service to determine dependencies between bundles. Since it's highly dependent on an external service, it might be better to use a listener based implementation for poor performing environments.

This implementation does consider required bundles.

getImportedBundles

public ImportedBundle[] getImportedBundles(org.osgi.framework.Bundle bundle)

Description copied from interface: DependencyResolver

Returns the bundles imported by the given bundle. It's up to the implementation to consider required bundles, bundle class-path and dynamic imports.

The returned array should not contain duplicates (each imported bundle should be present exactly once).

In general it is not expected to have knowledge about runtime loading (such as dynamic imports).

Specified by:

getImportedBundles in interface DependencyResolver

Parameters:

bundle - OSGi bundle for which imported bundles will be determined

Returns:

a not-null array of importing bundles
