Class OsgiBundleScope

java.lang.Object

org.eclipse.gemini.blueprint.context.support.internal.scope.OsgiBundleScope

All Implemented Interfaces:

org.springframework.beans.factory.config.Scope, org.springframework.beans.factory.DisposableBean

public class OsgiBundleScope
extends java.lang.Object
implements org.springframework.beans.factory.config.Scope, org.springframework.beans.factory.DisposableBean

OSGi bundle Scope implementation. Will allow per--calling-bundle object instance, thus this scope becomes useful when enabled on localBeans exposed as OSGi services.
