Interface SmartInstantiationAwareBeanPostProcessor

All Superinterfaces:

BeanPostProcessor, InstantiationAwareBeanPostProcessor

All Known Implementing Classes:

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 InstantiationAwareBeanPostProcessor interface or derive from the InstantiationAwareBeanPostProcessorAdapter class. New methods might be added to this interface even in point releases.

Since:

2.0.3
