Interface AfterTypeDiscovery

public interface AfterTypeDiscovery

This event type is thrown by the container after type discovery is complete. If any observer method of the AfterTypeDiscovery event throws an exception, the exception is treated as a definition error by the container.

Any observer of this event is permitted to add classes to, or remove classes from, the list of alternatives, list of interceptors or list of decorators. The container will use the final values of these lists, after all observers have been called, to determine the enabled alternatives, interceptors, and decorators for application. Changes made to these lists after the invocation of the last observer method of the AfterTypeDiscovery are ignored.

1.1

Method Summary

Modifier and Type	Method and Description
void	addAnnotatedType(AnnotatedType<?> type, String id) Adds a given AnnotatedType to the set of types which will be scanned during bean discovery.
<T> AnnotatedTypeConfigurator<T>	addAnnotatedType(Class<T> type, String id) Obtains a new AnnotatedTypeConfigurator to configure a new AnnotatedType and add it to the set of types which will be scanned during bean discovery at the end of the observer invocation.

List<Class<?>>	getDecorators()
List<Class<?>>	getInterceptors()

Method Detail

getAlternatives

List<Class<?>> getAlternatives()

Returns:

the list of enabled alternatives for the application, sorted by priority in ascending order. Alternatives enabled for a bean archive are not included.

Throws:

IllegalStateException - if called outside of the observer method invocation

getInterceptors

List<Class<?>> getInterceptors()

Returns:

the list of enabled interceptors for the application, sorted by priority in ascending order. Interceptors enabled for a bean archive are not included.

Throws:

IllegalStateException - if called outside of the observer method invocation

getDecorators

List<Class<?>> getDecorators()

Returns:

the list of enabled decorators for the application, sorted by priority in ascending order. Decorators enabled for a bean archive are not included.

Throws:

IllegalStateException - if called outside of the observer method invocation

addAnnotatedType

void addAnnotatedType(AnnotatedType<?> type,
                      String id)

Adds a given AnnotatedType to the set of types which will be scanned during bean discovery.

Thanks to the id parameter, this method allows multiple annotated types, based on the same underlying type, to be defined. AnnotatedTypes discovered by the container use the fully qualified class name of AnnotatedType.getJavaClass() to identify the type.

AfterBeanDiscovery.getAnnotatedType(Class, String) and AfterBeanDiscovery.getAnnotatedTypes(Class) allows annotated types to be obtained by identifier.

Parameters:

type - The AnnotatedType to add for later scanning

id - the identifier used to distinguish this AnnotatedType from an other one based on the same underlying type

Throws:

IllegalStateException - if called outside of the observer method invocation

addAnnotatedType

<T> AnnotatedTypeConfigurator<T> addAnnotatedType(Class<T> type,
                                                  String id)

Obtains a new AnnotatedTypeConfigurator to configure a new AnnotatedType and add it to the set of types which will be scanned during bean discovery at the end of the observer invocation. Calling this method multiple times will return a new AnnotatedTypeConfigurator.

Thanks to the id parameter, this method allows multiple annotated types, based on the same underlying type, to be defined. AnnotatedTypes discovered by the container use the fully qualified class name of AnnotatedType.getJavaClass() to identify the type.

AfterBeanDiscovery.getAnnotatedType(Class, String) and AfterBeanDiscovery.getAnnotatedTypes(Class) allows annotated types to be obtained by identifier.

Each call returns a new AnnotatedTypeConfigurator.

Parameters:

type - class used to initialized the type and annotations on the AnnotatedTypeConfigurator

id - the identifier used to distinguish this AnnotatedType from an other one based on the same underlying type

Returns:

a non reusable AnnotatedTypeConfigurator to configure the new AnnotatedType

Throws:

IllegalStateException - if called outside of the observer method invocation
