Interface ProcessBeanAttributes<T>

Type Parameters:

T - The class of the bean

public interface ProcessBeanAttributes<T>

The container fires an event of this type for each enabled bean, interceptor or decorator deployed in a bean archive before registering the Bean object.

No event is fired for New qualified beans.

Any observer of this event is permitted to wrap and/or replace the BeanAttributes by calling either setBeanAttributes(BeanAttributes) or configureBeanAttributes(). If both methods are called within an observer notification an IllegalStateException is thrown. The container must use the final value of this property, after all observers have been called, to manage instances of the bean.

If any observer method of a ProcessBeanAttributes event throws an exception, the exception is treated as a definition error by the container.

1.1

Method Summary

Modifier and Type	Method and Description
void	addDefinitionError(Throwable t) Registers a definition error with the container, causing the container to abort deployment after bean discovery is complete.
BeanAttributesConfigurator<T>	configureBeanAttributes() returns a BeanAttributesConfigurator initialized with the BeanAttributes processed by this event to configure a new BeanAttributes that will replace the original one at the end of the observer invocation.
Annotated	getAnnotated()
BeanAttributes<T>	getBeanAttributes()
void	ignoreFinalMethods() Instructs the container to ignore all non-static, final methods with public, protected or default visibility declared on any bean type of the specific bean during validation of injection points that require proxyable bean type.
void	setBeanAttributes(BeanAttributes<T> beanAttributes) Replaces the BeanAttributes.
void	veto() Forces the container to ignore the bean.

Method Detail

getAnnotated

Annotated getAnnotated()

Returns:

the AnnotatedType representing the managed bean class or session bean class, the AnnotatedMethod representing the producer field, or the AnnotatedField representing the producer field

Throws:

IllegalStateException - if called outside of the observer method invocation

getBeanAttributes

BeanAttributes<T> getBeanAttributes()

Returns:

the BeanAttributes object that will be used by the container to manage instances of the bean

Throws:

IllegalStateException - if called outside of the observer method invocation

setBeanAttributes

void setBeanAttributes(BeanAttributes<T> beanAttributes)

Replaces the BeanAttributes.

Parameters:

beanAttributes - the new BeanAttributes to use

Throws:

IllegalStateException - if called outside of the observer method invocation

configureBeanAttributes

BeanAttributesConfigurator<T> configureBeanAttributes()

returns a BeanAttributesConfigurator initialized with the BeanAttributes processed by this event to configure a new BeanAttributes that will replace the original one at the end of the observer invocation. Each call returns the same BeanAttributesConfigurator.

Returns:

a non reusable BeanAttributesConfigurator to configure the replacing BeanAttributes

Throws:

IllegalStateException - if called outside of the observer method invocation

Since:

2.0

addDefinitionError

void addDefinitionError(Throwable t)

Registers a definition error with the container, causing the container to abort deployment after bean discovery is complete.

Parameters:

t - the error to add

Throws:

IllegalStateException - if called outside of the observer method invocation

veto

void veto()

Forces the container to ignore the bean.

Throws:

IllegalStateException - if called outside of the observer method invocation

ignoreFinalMethods

void ignoreFinalMethods()

Instructs the container to ignore all non-static, final methods with public, protected or default visibility declared on any bean type of the specific bean during validation of injection points that require proxyable bean type.

These method should never be invoked upon bean instances. Otherwise, unpredictable behavior results.

Throws:

IllegalStateException - if called outside of the observer method invocation

2.0
