Class LocalBundleContext

java.lang.Object

org.eclipse.gemini.blueprint.service.importer.support.LocalBundleContext

public abstract class LocalBundleContext
extends java.lang.Object

Class containing static methods used to obtain information about the current OSGi service invocation.

The getInvokerBundleContext() method offers access to the BundleContext of the entity accessing an OSGi service. The invoked entity can thus discover information about the caller context.

The functionality in this class might be used by a target object that needed access to resources on the invocation. However, this approach should not be used when there is a reasonable alternative, as it makes application code dependent on usage under AOP and the Spring Dynamic Modules and AOP framework in particular.
