Class AbstractOSGIAnnotationBeanPostProcessor<A extends Annotation>

java.lang.Object

org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessorAdapter

org.apache.james.container.spring.lifecycle.osgi.AbstractOSGIAnnotationBeanPostProcessor<A>

Type Parameters:

A -

All Implemented Interfaces:

org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessor, org.springframework.beans.factory.config.SmartInstantiationAwareBeanPostProcessor, org.springframework.osgi.context.BundleContextAware

Direct Known Subclasses:

OSGIPersistenceUnitAnnotationBeanPostProcessor, OSGIResourceAnnotationBeanPostProcessor

public abstract class AbstractOSGIAnnotationBeanPostProcessor<A extends Annotation>
extends org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessorAdapter
implements org.springframework.osgi.context.BundleContextAware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware

Abstract base class for BeanPostProcessor implementations which need to wire stuff via annotations and need to be functional via OSGI. Many of this code is borrowed from the spring-dm's class org.springframework.osgi.extensions.annotation.ServiceReferenceInjectionBeanPostProcessor. *
