public abstract class InstantiationAwareBeanPostProcessorAdapter extends Object implements SmartInstantiationAwareBeanPostProcessor
SmartInstantiationAwareBeanPostProcessor
as no-ops, which will not change normal processing of each bean instantiated
by the container. Subclasses may override merely those methods that they are
actually interested in.
Note that this base class is only recommendable if you actually require
InstantiationAwareBeanPostProcessor functionality. If all you need
is plain BeanPostProcessor functionality, prefer a straight
implementation of that (simpler) interface.

determineCandidateConstructors(Class<?> beanClass,
String beanName)
Determine the candidate constructors to use for the given bean.

Object |
getEarlyBeanReference(Object bean,
String beanName)
Obtain a reference for early access to the specified bean,
typically for the purpose of resolving a circular reference.
|
Object |
postProcessAfterInitialization(Object bean,

Apply this BeanPostProcessor to the given new bean instance after any bean
initialization callbacks (like InitializingBean's
afterPropertiesSet
or a custom init-method). |
boolean |
postProcessAfterInstantiation(Object bean,
String beanName)
Perform operations after the bean has been instantiated, via a constructor or factory method,
but before Spring property population (from explicit properties or autowiring) occurs.
|
Object |
postProcessBeforeInitialization(Object bean,
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). |
Object |
postProcessBeforeInstantiation(Class<?> beanClass,
String beanName)
Apply this BeanPostProcessor before the target bean gets instantiated.
|
PropertyValues |
postProcessProperties(PropertyValues pvs,
Object bean,
String beanName)
Post-process the given property values before the factory applies them
to the given bean, without any need for property descriptors.

Deprecated.

Class<?> |
predictBeanType(Class<?> beanClass,

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

SmartInstantiationAwareBeanPostProcessorThis callback gives post-processors a chance to expose a wrapper
early - that is, before the target bean instance is fully initialized.
The exposed object should be equivalent to the what
BeanPostProcessor.postProcessBeforeInitialization(java.lang.Object, java.lang.String) / BeanPostProcessor.postProcessAfterInitialization(java.lang.Object, java.lang.String)
would expose otherwise. Note that the object returned by this method will
be used as bean reference unless the post-processor returns a different
wrapper from said post-process callbacks. In other words: Those post-process
callbacks may either eventually expose the same reference or alternatively
return the raw bean instance from those subsequent callbacks (if the wrapper
for the affected bean has been built for a call to this method already,
it will be exposes as final bean reference by default).
The default implementation returns the given bean as-is.

InstantiationAwareBeanPostProcessorIf a non-null object is returned by this method, the bean creation process
will be short-circuited. The only further processing applied is the
BeanPostProcessor.postProcessAfterInitialization(java.lang.Object, java.lang.String) callback from the configured
BeanPostProcessors.
This callback will be applied to bean definitions with their bean class, as well as to factory-method definitions in which case the returned bean type will be passed in here.
Post-processors may implement the extended
SmartInstantiationAwareBeanPostProcessor interface in order
to predict the type of the bean object that they are going to return here.
The default implementation returns null.

InstantiationAwareBeanPostProcessorImplementations should return null (the default) if they provide a custom
InstantiationAwareBeanPostProcessor.postProcessPropertyValues(org.springframework.beans.PropertyValues, java.beans.PropertyDescriptor[], java.lang.Object, java.lang.String) implementation, and pvs otherwise.
In a future version of this interface (with InstantiationAwareBeanPostProcessor.postProcessPropertyValues(org.springframework.beans.PropertyValues, java.beans.PropertyDescriptor[], java.lang.Object, java.lang.String) removed),
the default implementation will return the given pvs as-is directly.

InstantiationAwareBeanPostProcessorAlso allows for replacing the property values to apply, typically through creating a new MutablePropertyValues instance based on the original PropertyValues, adding or removing specific values.

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
InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) method,
in contrast to all other BeanPostProcessor callbacks.
