Interface SmartInstantiationAwareBeanPostProcessor

All Superinterfaces:

BeanPostProcessor, InstantiationAwareBeanPostProcessor

All Known Implementing Classes:

AutowiredAnnotationBeanPostProcessor, InstantiationAwareBeanPostProcessorAdapter, RequiredAnnotationBeanPostProcessor, ScriptFactoryPostProcessor

public interface SmartInstantiationAwareBeanPostProcessor
extends InstantiationAwareBeanPostProcessor

Extension of the InstantiationAwareBeanPostProcessor interface, adding a callback for predicting the eventual type of a processed bean.

NOTE: This interface is a special purpose interface, mainly for internal use within the framework. In general, application-provided post-processors should simply implement the plain BeanPostProcessor interface or derive from the InstantiationAwareBeanPostProcessorAdapter class. New methods might be added to this interface even in point releases.

Since:

2.0.3

Method Detail

predictBeanType

Class predictBeanType(Class beanClass,
                      String beanName)
                      throws BeansException

Predict the type of the bean to be eventually returned from this processor's InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class, java.lang.String) callback.

Parameters:

beanClass - the raw class of the bean

beanName - the name of the bean

Returns:

the type of the bean, or null if not predictable

Throws:

BeansException - in case of errors

determineCandidateConstructors

Constructor[] determineCandidateConstructors(Class beanClass,
                                             String beanName)
                                             throws BeansException

Determine the candidate constructors to use for the given bean.

Parameters:

beanClass - the raw class of the bean

beanName - the name of the bean

Returns:

the candidate constructors, or null if none specified

Throws:

BeansException - in case of errors
