Constructor Detail

BeanInjectionTarget

public BeanInjectionTarget(EnhancedAnnotatedType<T> type,
                   Bean<T> bean,
                   BeanManagerImpl beanManager)

Method Detail

initInjector

protected Injector<T> initInjector(EnhancedAnnotatedType<T> type,
                       Bean<T> bean,
                       BeanManagerImpl beanManager)

Overrides:

initInjector in class BasicInjectionTarget<T>

postConstruct

public void postConstruct(T instance)

Description copied from interface: InjectionTarget

Calls the PostConstruct callback, if it exists, according to the semantics required by the Java EE platform specification.

Specified by:

postConstruct in interface InjectionTarget<T>

Overrides:

postConstruct in class BasicInjectionTarget<T>

Parameters:

instance - The instance on which to invoke the PostConstruct method

preDestroy

public void preDestroy(T instance)

Description copied from interface: InjectionTarget

Calls the PreDestroy callback, if it exists, according to the semantics required by the Java EE platform specification.

Specified by:

preDestroy in interface InjectionTarget<T>

Overrides:

preDestroy in class BasicInjectionTarget<T>

Parameters:

instance - The instance on which to invoke the PreDestroy method

dispose

public void dispose(T instance)

Description copied from interface: Producer

Destroys the instance.

If the Producer represents a class, then this operation does nothing.

If the Producer represents a producer field or method, this calls the disposer method, if any, on a contextual instance of the bean that declares the disposer method or performs any additional required cleanup, if any, to destroy state associated with a resource.

Specified by:

dispose in interface Producer<T>

Overrides:

dispose in class BasicInjectionTarget<T>

Parameters:

instance - The instance to dispose

isInterceptor

protected boolean isInterceptor()

isDecorator

protected boolean isDecorator()

isInterceptionCandidate

protected boolean isInterceptionCandidate()

initializeInterceptionModel

protected void initializeInterceptionModel(EnhancedAnnotatedType<T> annotatedType)

initializeAfterBeanDiscovery

public void initializeAfterBeanDiscovery(EnhancedAnnotatedType<T> annotatedType)

Overrides:

initializeAfterBeanDiscovery in class BasicInjectionTarget<T>

setupConstructorInterceptionInstantiator

protected void setupConstructorInterceptionInstantiator(InterceptionModel<ClassMetadata<?>> interceptionModel)

checkNoArgsConstructor

protected void checkNoArgsConstructor(EnhancedAnnotatedType<T> type)

checkDecoratedMethods

protected void checkDecoratedMethods(EnhancedAnnotatedType<T> type,
                         List<Decorator<?>> decorators)

produce

public T produce(CreationalContext<T> ctx)

Description copied from interface: Producer

Causes an instance to be produced via the Producer.

If the Producer represents a class, this will invoke the constructor annotated Inject if it exists, or the constructor with no parameters otherwise. If the class has interceptors, produce() is responsible for building the interceptors and decorators of the instance.

If the Producer represents a producer field or method, this will invoke the producer method on, or access the producer field of, a contextual instance of the bean that declares the producer.

Specified by:

produce in interface Producer<T>

Overrides:

produce in class BasicInjectionTarget<T>

Parameters:

ctx - The CreationalContext to use for the produced object

Returns:

the instance produced

initInvoker

protected LifecycleCallbackInvoker<T> initInvoker(EnhancedAnnotatedType<T> type)

Overrides:

initInvoker in class BasicInjectionTarget<T>

getBean

public Bean<T> getBean()

Description copied from class: AbstractProducer

Returns a Bean this producer is associated with or null if no such bean exists.

Overrides:

getBean in class BasicInjectionTarget<T>
