Interface BeanPostProcessorService

All Known Subinterfaces:

All Known Implementing Classes:

public interface BeanPostProcessorService

BeanPostProcessor service that allows bundles to contribute to the programming model of WLEvS. This avoids runtime and build-time dependencies between providers and the programming model. The API differs from regular BeanPostProcessors in that it is stateless with all the required state information passed in.

Method Summary

void	afterPropertiesSet(BundleContext context) Initialization callback for this context
void	destroy(BundleContext context) Destruction callback for this context
java.lang.Object	postProcessAfterInitialization(BundleContext context, ConfigurableListableBeanFactory factory, java.lang.Object bean, java.lang.String beanName) Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).
void	postProcessBeforeDestruction(BundleContext context, ConfigurableListableBeanFactory factory, java.lang.Object bean, java.lang.String beanName) Apply this BeanPostProcessor to the given bean instance before its destruction.
java.lang.Object	postProcessBeforeInitialization(BundleContext context, ConfigurableListableBeanFactory factory, java.lang.Object bean, java.lang.String beanName) Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).

Method Detail

postProcessBeforeInitialization

public java.lang.Object postProcessBeforeInitialization(BundleContext context,
                                                        ConfigurableListableBeanFactory factory,
                                                        java.lang.Object bean,
                                                        java.lang.String beanName)
                                                 throws BeansException

Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

Parameters:

context - bundle

factory - the bean factory used by the application context

bean - the new bean instance

beanName - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one

Throws:

org.springframework.beans.BeansException - in case of errors

org.springframework.beans.factory.InitializingBean#afterPropertiesSet

postProcessAfterInitialization

public java.lang.Object postProcessAfterInitialization(BundleContext context,
                                                       ConfigurableListableBeanFactory factory,
                                                       java.lang.Object bean,
                                                       java.lang.String beanName)
                                                throws BeansException

Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding bean instanceof FactoryBean checks.

This callback will also be invoked after a short-circuiting triggered by a org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessor#postProcessBeforeInstantiation method, in contrast to all other BeanPostProcessor callbacks.

Parameters:

context - bundle

factory - the bean factory used by the application context

bean - the new bean instance

beanName - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one

Throws:

org.springframework.beans.BeansException - in case of errors

See Also:

org.springframework.beans.factory.InitializingBean#afterPropertiesSet, org.springframework.beans.factory.FactoryBean

postProcessBeforeDestruction

public void postProcessBeforeDestruction(BundleContext context,
                                         ConfigurableListableBeanFactory factory,
                                         java.lang.Object bean,
                                         java.lang.String beanName)
                                  throws BeansException

Apply this BeanPostProcessor to the given bean instance before its destruction. Can invoke custom destruction callbacks.

Like DisposableBean's destroy and a custom destroy method, this callback just applies to singleton beans in the factory (including inner beans).

Parameters:

context - bundle

factory - the bean factory used by the application context

bean - the bean instance to be destroyed

beanName - the name of the bean

Throws:

org.springframework.beans.BeansException - in case of errors

org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.support.AbstractBeanDefinition#setDestroyMethodName

afterPropertiesSet

public void afterPropertiesSet(BundleContext context)
                        throws java.lang.Exception

Initialization callback for this context

Parameters:

context -

Throws:

java.lang.Exception -

destroy

public void destroy(BundleContext context)
             throws java.lang.Exception

Destruction callback for this context

Parameters:

context -

Throws:

java.lang.Exception -
