Interface AfterBeanDiscovery

public interface AfterBeanDiscovery

The event type of the second event fired by the container when it has fully completed the bean discovery process, validated that there are no definition errors relating to the discovered beans, and registered Bean and ObserverMethod objects for the discovered beans, but before detecting deployment problems.

A portable extension may take advantage of this event to register beans, interceptors, decorators, observer methods and custom context objects with the container.

     void afterBeanDiscovery(@Observes AfterBeanDiscovery event, BeanManager manager) { ... }
 

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

Method Summary

Modifier and Type	Method and Description
<T> BeanConfigurator<T>	addBean() Obtains a new BeanConfigurator to configure a new Bean and add it at the end of the observer invocation.
void	addBean(Bean<?> bean) Fires an event of type ProcessBean containing the given Bean and then registers the Bean with the container, thereby making a bean which is not an interceptor nor a decorator available for injection into other beans.
void	addContext(Context context) Registers a custom Context object with the container.
void	addDefinitionError(Throwable t) Registers a definition error with the container, causing the container to abort deployment after all observers have been notified.
<T> ObserverMethodConfigurator<T>	addObserverMethod() obtains a new ObserverMethodConfigurator to configure a new ObserverMethod and add it at the end of the observer invocation.
void	addObserverMethod(ObserverMethod<?> observerMethod) Fires an event of type ProcessObserverMethod containing the given ObserverMethod and then registers the ObserverMethod with the container, thereby making it available for event notifications.
<T> AnnotatedType<T>	getAnnotatedType(Class<T> type, String id) Obtain the AnnotatedType that may be used to read the annotations of the given class or interface as defined during container initialization.
<T> Iterable<AnnotatedType<T>>	getAnnotatedTypes(Class<T> type) Obtain the AnnotatedTypes that may be used to read the annotations of the given class or interface as defined during container initialization.

Method Detail

addDefinitionError

void addDefinitionError(Throwable t)

Registers a definition error with the container, causing the container to abort deployment after all observers have been notified.

Parameters:

t - The definition error as a Throwable

Throws:

IllegalStateException - if called outside of the observer method invocation

addBean

void addBean(Bean<?> bean)

Fires an event of type ProcessBean containing the given Bean and then registers the Bean with the container, thereby making a bean which is not an interceptor nor a decorator available for injection into other beans. The given Bean may implement Interceptor or Decorator.

Parameters:

bean - The bean to add to the deployment

Throws:

IllegalStateException - if called outside of the observer method invocation

addBean

<T> BeanConfigurator<T> addBean()

Obtains a new BeanConfigurator to configure a new Bean and add it at the end of the observer invocation. It will then fire an event of type ProcessBean containing the built Bean from this configuration and then register it with the container, thereby making it available for injection into other beans. Each call returns a new BeanConfigurator.

Returns:

a non reusable BeanConfigurator to configure the bean to add

Throws:

IllegalStateException - if called outside of the observer method invocation

Since:

2.0

addObserverMethod

void addObserverMethod(ObserverMethod<?> observerMethod)

Fires an event of type ProcessObserverMethod containing the given ObserverMethod and then registers the ObserverMethod with the container, thereby making it available for event notifications.

Parameters:

observerMethod - The custom observer method to add to the deployment

Throws:

IllegalStateException - if called outside of the observer method invocation

addObserverMethod

<T> ObserverMethodConfigurator<T> addObserverMethod()

obtains a new ObserverMethodConfigurator to configure a new ObserverMethod and add it at the end of the observer invocation. It will then fire an event of type ProcessObserverMethod containing the built ObserverMethod from this configuration and then registers the ObserverMethod with the container, thereby making it available for event notifications. Each call returns a new ObserverMethodConfigurator.

Returns:

a non reusable ObserverMethodConfigurator instance

Throws:

IllegalStateException - if called outside of the observer method invocation

Since:

2.0

addContext

void addContext(Context context)

Registers a custom Context object with the container.

Parameters:

context - The custom context to add to the deployment

Throws:

IllegalStateException - if called outside of the observer method invocation

getAnnotatedType

<T> AnnotatedType<T> getAnnotatedType(Class<T> type,
                                      String id)

Obtain the AnnotatedType that may be used to read the annotations of the given class or interface as defined during container initialization.

Type Parameters:

T - the class or interface

Parameters:

type - the Class object

id - the type identifier. If null, the fully qualifier class name of type is used

Returns:

the AnnotatedType

Throws:

IllegalStateException - if called outside of the observer method invocation

Since:

1.1

getAnnotatedTypes

<T> Iterable<AnnotatedType<T>> getAnnotatedTypes(Class<T> type)

Obtain the AnnotatedTypes that may be used to read the annotations of the given class or interface as defined during container initialization.

Type Parameters:

T - the class or interface

Parameters:

type - the Class object

Returns:

the AnnotatedTypes

Throws:

IllegalStateException - if called outside of the observer method invocation

Since:

1.1
