Class BasicInjectionTarget<T>

java.lang.Object

org.jboss.weld.injection.producer.AbstractProducer<T>

org.jboss.weld.injection.producer.BasicInjectionTarget<T>

All Implemented Interfaces:

javax.enterprise.inject.spi.InjectionTarget<T>, javax.enterprise.inject.spi.Producer<T>

Direct Known Subclasses:

BeanInjectionTarget, NonProducibleInjectionTarget

public class BasicInjectionTarget<T>
extends AbstractProducer<T>
implements javax.enterprise.inject.spi.InjectionTarget<T>

Basic InjectionTarget implementation. The implementation supports:

• @Inject injection + initializers
• @PostConstruct/@PreDestroy callbacks

Interception and decoration is not supported but can be added using extension points.

BasicInjectionTarget

public BasicInjectionTarget(EnhancedAnnotatedType<T> type,
                    javax.enterprise.inject.spi.Bean<T> bean,
                    BeanManagerImpl beanManager)

Method Detail

checkType

protected void checkType(EnhancedAnnotatedType<T> type)

produce

public T produce(javax.enterprise.context.spi.CreationalContext<T> ctx)

Specified by:

produce in interface javax.enterprise.inject.spi.Producer<T>

inject

public void inject(T instance,
          javax.enterprise.context.spi.CreationalContext<T> ctx)

Specified by:

inject in interface javax.enterprise.inject.spi.InjectionTarget<T>

postConstruct

public void postConstruct(T instance)

Specified by:

postConstruct in interface javax.enterprise.inject.spi.InjectionTarget<T>

preDestroy

public void preDestroy(T instance)

Specified by:

preDestroy in interface javax.enterprise.inject.spi.InjectionTarget<T>

dispose

public void dispose(T instance)

Specified by:

dispose in interface javax.enterprise.inject.spi.Producer<T>

getInjectionPoints

public Set<javax.enterprise.inject.spi.InjectionPoint> getInjectionPoints()

Specified by:

getInjectionPoints in interface javax.enterprise.inject.spi.Producer<T>

getType

protected javax.enterprise.inject.spi.AnnotatedType<T> getType()

getBeanManager

protected BeanManagerImpl getBeanManager()

getInstantiator

public Instantiator<T> getInstantiator()

setInstantiator

public void setInstantiator(Instantiator<T> instantiator)

hasInterceptors

public boolean hasInterceptors()

hasDecorators

public boolean hasDecorators()

initializeAfterBeanDiscovery

protected void initializeAfterBeanDiscovery(EnhancedAnnotatedType<T> annotatedType)

initInstantiator

protected Instantiator<T> initInstantiator(EnhancedAnnotatedType<T> type,
                               javax.enterprise.inject.spi.Bean<T> bean,
                               BeanManagerImpl beanManager,
                               Set<javax.enterprise.inject.spi.InjectionPoint> injectionPoints)

Returns an instantiator that will be used to create a new instance of a given component. If the instantiator uses a constructor with injection points, the implementation of the initInstantiator(EnhancedAnnotatedType, Bean, BeanManagerImpl, Set) method is supposed to register all these injection points within the injectionPoints set passed in as a parameter.

initInjector

protected Injector<T> initInjector(EnhancedAnnotatedType<T> type,
                       javax.enterprise.inject.spi.Bean<T> bean,
                       BeanManagerImpl beanManager)

initInvoker

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

getAnnotated

public javax.enterprise.inject.spi.AnnotatedType<T> getAnnotated()

Specified by:

getAnnotated in class AbstractProducer<T>

getInjector

public Injector<T> getInjector()

getLifecycleCallbackInvoker

public LifecycleCallbackInvoker<T> getLifecycleCallbackInvoker()

toString

public String toString()

Overrides:

toString in class Object

getBean

public javax.enterprise.inject.spi.Bean<T> getBean()

Description copied from class: AbstractProducer

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

Specified by:

getBean in class AbstractProducer<T>
