Interface BundleClassLoaderHelper

All Known Implementing Classes:
DefaultBundleClassLoaderHelper
public interface BundleClassLoaderHelper
BundleClassLoaderHelper

Provides a ClassLoader for an OSGi Bundle.

The default implementation uses a specification-compliant approach that delegates to the standard OSGi Bundle API methods (Bundle.loadClass, Bundle.getResource, Bundle.getResources) instead of using reflection to access container-specific internal classloaders.

Custom implementations can be provided via OSGi fragments by implementing a class with the name specified by CLASS_NAME.
